INTRODUCTION

The Social Security Old-Age, Survivors, and Disability Insurance (OASDI) program makes monthly income

available to insured workers and their families at retirement, death, or disability. The OASDI program consists of two

parts. Retired workers, their families, and survivors of deceased workers receive monthly benefits under the Old-Age

and Survivors Insurance (OASI) program. Disabled workers and their families receive monthly benefits under the

Disability Insurance (DI) program.

The most recent work dedicated to analyzing the experience of worker beneficiaries under the DI program is

Actuarial Study #122, Social Security Disability Insurance Program Worker Experience (May 2011). That earlier

study examined historical data with regard to disability incidence and benefit termination through calendar year 2009.

A comprehensive analysis of termination activity of the DI rolls was also presented based on 100 percent worker data

collected for the 5-year period 2001-05. The overall content of Actuarial Study #123, and the methods used to prepare

those results, are consistent with those of the prior study; namely, disability incidence and benefit termination is

examined through calendar year 2013, and a comprehensive analysis of termination activity is presented for the

5-year period 2006-10. Details of the underlying methodology for table construction are outlined in the appendix of

this study.

While this study provides extensive information on recent actual DI disabled worker experience, it does not report on

the projected future operations of the DI Trust Fund, nor does it provide information on other types of disability

benefits administered by the Social Security Administration. Much information on these other topics is available in

various publications on our website at http://www.ssa.gov/OACT. In particular, projections of the future actuarial

status and financial operations of the OASI or DI Trust Funds are presented in the Annual Report of the Board of

Trustees of the Federal Old-Age and Survivors Insurance and Federal Disability Insurance Trust Funds (see http://

www.ssa.gov/OACT/TR/2015/index.html for the detailed information on the 2015 edition of that report).

SOCIAL SECURITY DISABILITY INSURANCE PROGRAM

WORKER EXPERIENCE

I. ENTITLEMENT TO DISABILITY INSURANCE BENEFITS

The Social Security Old-Age, Survivors, and Disability Insurance (OASDI) program provides for monthly disability insurance benefits after the onset of a severe physical or mental

impairment. To become entitled to such benefits a worker

must:

• Be insured for disability under the Social Security Act; 

• File a claim for disability insurance benefits; 

• Meet the definition of disability set forth in the Act;

• Complete a 5-month waiting period; and

• Have not attained normal retirement age (see table below).

A worker’s cash benefit is classified as an award at the time of

initial payment. Additional auxiliary benefits may also be payable to other family members based on the earnings record of

the entitled worker. This study analyzes the experience of disabled workers of the Social Security Disability Insurance (DI)

program as described under title II of the Social Security Act.

A. Disability Insured Status

To qualify for Social Security benefits for themselves and their

dependents, individuals must work in employment covered by

Social Security or be self-employed for a certain period of

time. Credit for this work is based on the amount of wages or

self-employment income earned and is measured in quarters of

coverage (QCs), or credits.

1

Entitlement to any benefit depends on whether the number of

credits earned by a worker is sufficient to meet various insured

status requirements. To be considered for disability benefits, a

worker must be disability insured. This requires having

obtained a specific number of credits in recent quarters, as well

as enough total credits to be fully insured—at least 6 and no

more than 40 credits are required for this insured status.2 The

recency-of-work test is satisfied if the worker has earned at

least 20 credits during a 40-quarter period that ends with the

quarter in which the disability begins.

A special recency-of-work test for younger workers provides

an alternative to the 20/40 requirement. A worker who

becomes disabled before the quarter in which he or she attains

age 31 satisfies the special test requirement if credits have been

earned for at least one-half of the quarters during the period

beginning with the quarter after the quarter the worker attained

age 21, and ending with the quarter in which the disability

began. If this period contains 12 or fewer quarters—that is, if

the disability begins in the quarter the worker attains age 24 or

earlier—then a minimum of six credits must be earned in the

12-quarter period ending with the quarter in which the disability began.

Note that an individual who is disabled because of statutory

blindness is not required to satisfy the recency-of-work test.

Disability insured status is granted if the worker is fully

insured only.

B. Filing an Application

An individual must file an application to become entitled to

benefits. In general, a claimant may file for DI benefits at any

time after onset of disability. A claimant who files after the first

month he could have been entitled to benefits may receive retroactive benefits for up to 12 months immediately prior to the

month of filing.

Retroactive benefits are also payable for any month of entitlement beginning with the month of filing and leading up to the

month of award. The number of months of retroactive benefits

paid in these instances ultimately depends on how long it takes

to receive a favorable determination of disability.

1 In 2015, a worker receives one credit (up to a maximum of four) for each 

$1,220 of annual covered earnings. This amount is indexed each year by the 

increase in average wages. For determining QCs, different rules apply to earnings before 1978, and a simplified method applies for the 1937-50 period.

2 A fully insured worker has at least one credit (whenever acquired) for each 

year starting with the year the worker attains age 22 and ending with the year 

before the year the worker attains age 62, becomes disabled, or dies (whichever occurs earliest)—credits are not required for years that are partially or 

fully within a period of disability.

A claimant may also file for benefits no later than 12 months

after the month in which the disability ends. In these instances,

retroactive benefits are payable only for those months of entitlement within the 12-month period immediately prior to the

month of filing. For purposes of establishing a closed period of

disability freeze3

, there are exceptions where the claimant is

allowed to file no later than 36 months after the month in

which disability ends.

C. Definition of Disability

For purposes of entitlement to DI benefits, disability is defined

as the inability to engage in any substantial gainful activity

(SGA) by reason of any medically determinable physical or

mental impairment. The impairment must be expected to result

in death or to last for a continuous period of at least 12

months—called the duration requirement. Specifically, the disability must prevent the claimant from performing previous

work, or engaging in any other kind of work in which a significant number of jobs exist. It doesn’t matter whether or not such

work is available in the claimant’s immediate area, or whether

the claimant would be hired upon applying for work.

SSA uses a five-step sequential evaluation process to decide

whether disability exists. Claim processing for title II benefits

of the Act stops as soon as a determination—favorable or unfavorable—can be reached.

Step 1—Determine if claimant is engaging in SGA. If the

claimant is working and the work is SGA, then the claimant is

not disabled for Social Security purposes. Otherwise, the adjudicator continues with claim processing.

Step 2—Determine if impairment is “severe”. The adjudicator

will rule against a claim of disability if the impairment or combination of impairments do not significantly limit the claimant’s physical or mental ability to do basic work activities.

Otherwise claim processing continues.

Step 3—Determine if the severity of the impairment(s) meets

or medically equals a set of criteria in the Listing of Impairments. The adjudicator will rule in favor of a disability if the

impairment is counted among examples of impairments that

the agency considers severe enough to prevent the claimant

from engaging in SGA, and the duration requirement is met.

Otherwise claim processing continues.

Step 4—Determine if the claimant has the residual functional

capacity (RFC) to do his or her past relevant work. The adjudicator will assess what the claimant is still able to do despite

any limitations imposed by the impairment(s). If past work

duties cannot be accomplished, then claim processing continues.

Step 5—Determine if the impairment prevents claimant from

engaging in any other work that exists in significant numbers

in the national economy. The adjudicator will rule in favor of

a disability if the claimant is unable to perform any other work

given his or her RFC, age, education, and work experience, and

the duration requirement is met. Otherwise the claimant is

found to be not disabled for Social Security purposes.

The same definition of disability is applied to each of the following types of adult claimants:

• Disabled worker;

• Disabled child age 18 or over based on a disability which

occurred before age 22;

• Disabled widow(er) or surviving divorced spouse, age 50-

59, of a person who died fully insured—for benefits

payable after December 1990;

• Disabled adult under the Supplemental Security Income

(SSI) program as described under title XVI of the Social

Security Act—this means-tested cash benefits program is

also administered by the Social Security Administration

(SSA).

SSA uses special provisions for the evaluation of disability in

cases of statutory blindness, and widow(er) or surviving

divorced spouse benefits payable before January 1991.

D. Waiting Period

The waiting period for DI benefits consists of 5 consecutive

full calendar months beginning with the earliest full calendar

month throughout which the worker satisfied both the disability insured requirements and definition of disability. Benefits

are not payable during the waiting period. However, the waiting period is waived for individuals who had a prior period of

disability which ended within 5 years of the current period of

disability. In contrast, there is no waiting period for disability

benefits under the SSI program.

3 Freeze provisions were enacted to preserve the rights of individuals who are 

under a disability. Under these provisions, a worker’s earnings record can be 

“frozen” at a time he or she qualifies for a period of disability, thereby preserving insured status and preventing loss of future disability or retirement benefits 

which are computed without considering periods of disability.

II. EXPERIENCE OF DISABILITY DETERMINATIONS 

SSA takes applications for worker disability benefits through

field staff over the phone, in person in one of 1,300 local field

offices, or over the internet. State agencies make disability and

blindness determinations under regulations containing performance standards and other administrative requirements. Prior

to a medical determination of disability, a claim may be denied

for technical reasons, if the claimant:

• Is not disability insured;

• Is engaging in SGA;

• Dies before being disabled for 5 full months;

• Is not under normal retirement age (NRA).

Upon satisfying the technical aspects of the determination process, claims are forwarded to the state Disability Determination

Services for medical determination. The subsections below discuss in greater detail the following items: SGA, the impairment

listings, residual functional capacity, the determination and

appeals process, and the determination experience of the DI

program.

A. Substantial Gainful Activity (SGA)

Substantial work activity involves doing significant physical or

mental activities; gainful work activity is done for pay or profit.

In determining whether work is SGA, the state agencies consider things such as the nature and quality of the claimant’s

work, whether special conditions or equipment are needed to

do the work, the amount of time spent at work, and earnings.

Special evaluation guidelines exist for self-employed persons—agencies must measure the value of the claimant’s services to the operation of the business, number of hours worked,

skills, efficiency, and responsibilities.

SSA establishes certain earnings criteria to indicate whether an

individual is engaging in SGA. The monthly dollar amount

associated with defining SGA is specified in Federal regulations, and was originally set at $100 at the inception of the DI

program. This amount was updated on an ad hoc basis until

January 2001, at which time the regulations were revised to

provide for annual indexing of the SGA level based on the

increase in average wages. From 1990 through 2000, the SGA

level actually consisted of a primary amount and a lower secondary amount. Earnings above the primary amount ordinarily

demonstrated SGA, whereas earnings less than the secondary

amount demonstrated lack of SGA; earnings between the two

amounts required consideration of all circumstances related to

work activity. This tier structure was discontinued beginning in

2001. Since 1977, blind persons have been subject to a separate

SGA amount.4 Figure 1 shows a history of these SGA

amounts.

B. Listing of Impairments

To establish a disability, claimants must provide sufficient evidence of any medical condition in the form of symptoms, clinical signs, and laboratory findings. As mentioned in the

description of step 3 of the sequential evaluation process outlined in section I, SSA’s Listing of Impairments is used to

determine the severity of the disability. The listings are a set of

medical evaluation criteria in the Federal regulations that

describe physical and mental conditions which are so severe

that it is presumed that individuals whose medical conditions

meet or equal these criteria are disabled regardless of their age,

education, or work experience. The listings are arranged by

body system (musculoskeletal, cardiovascular, mental, etc.)

and include both diagnostic and severity criteria.

Many individuals are found to be disabled even though impairments fail to meet the level of severity detailed in the listings.

In these cases, an individual’s medical condition is evaluated in

conjunction with age, education, and job skills. These vocational factors are given increasing weight with the advancing

age of the worker, and are particularly significant in determining disability among workers age 50 or older.

C. Residual Functional Capacity (RFC)

Impairments and related symptoms, such as pain, may limit the

ability to work. Residual functional capacity measures the

most an individual can do given the physical and mental limitations. Careful assessment of RFC is the foundation of steps 4

and 5 of the sequential evaluation process. Limited ability to

4 As of 2015, a blind individual earning over $1,820 per month (net of impairment-related work expenses) is ordinarily considered to be engaging in SGA. 

The comparable amount for non-blind individuals is $1,090 per month.

perform certain physical demands such as sitting, standing,

walking, lifting, carrying, pushing, pulling, reaching, handling,

or stooping may reduce the ability to do work. Similarly, a limited ability to carry out certain mental activities like understanding, remembering, following instructions, or responding

appropriately to supervision may reduce the ability to do work.

Along with RFC, age and education play a vital role in step 5

of the evaluation process. When it comes to age, it is generally

considered that younger persons (under 50) will be able to

adjust to other work. Greater consideration is given to age and

education for those approaching advanced age (50-54); and it

is assumed that persons of advanced age (55 or older) are significantly hindered by vocational factors in their ability to

adjust to other work.

D. Determination and Appeals Process

Regulations describe the process of administrative review performed by the Disability Determination Services (DDS) and

the Office of Disability Adjudication and Review (ODAR).

The DDS develops medical evidence and renders the initial

determination of whether the claimant is disabled or blind

under the law. If dissatisfied with the initial DDS decision, the

claimant may request further administrative review by the

DDS, ODAR, and beyond to the federal courts. The review

process consists of several steps, which must be requested

within specified time intervals, and in the following order:

• Initial determination. This is the original determination

made by the DDS regarding entitlement to benefits.

• Reconsideration. If dissatisfied with an initial

determination, the claimant may ask the DDS to

reconsider it.

• Hearing before an administrative law judge (ALJ). If

dissatisfied with the reconsideration determination, the

claimant may appeal to ODAR and request a hearing

before an ALJ.

• Appeals Council (AC) review. If dissatisfied with the

decision of the ALJ, the claimant may request that the AC

review the decision. This constitutes the administration’s

final decision.

• Federal court review. If dissatisfied with the

administration’s final decision, the claimant may request

judicial review by filing an action in a Federal district

court.

In general, appeals must be filed within 60 days after the date

the claimant receives notice of the previous determination or

decision. The claimant or a representative, such as an attorney,

may submit new material evidence supporting the claim during

any step of the review process. Failure to appeal a determination or decision within the stated time period will result in loss

of the right to any further administrative or judicial review.

Many factors exist that affect the number of disability claims

filed as well as the rate at which these claims are allowed or

denied. However, the impact of any one factor is difficult to

gauge. In general, economic, demographic, and administrative

factors all have a direct effect on the size and scope of the DI

program. Below is a list of determinants which can significantly influence the number of claims filed and/or the rate of

favorable determinations5

:

• The rate of unemployment in the U.S. economy;

• The level or “attractiveness” of DI benefits vis-a-vis loss

of income;

• Level of the SGA amount;

• Changes in labor force participation or shifts in part-time

work which can affect insured status;

• Population growth and demographic shifts such as the

aging of the baby-boom generation;

• Technology to enhance the ability to work;

• Medical advancements or breakthroughs in the treatment

of specific disorders;

• Changes in regulations, standards, or methods used to

determine medical eligibility;

• Revisions to disability guidelines or impairment listings;

• Amount of administrative funding to process caseloads

and backlogs;

• Level of ODAR and Federal court involvement in the

appeals process;

• Results of appeals and class action suits challenging SSA’s

interpretation of the law;

• Actions by Federal, State, and local governments to

increase program awareness or encourage enrollment.

E. Determination Experience of DI Program

Table 1 presents data on the disposition of DI claims across the

various stages of medical review, for calendar years 2002-

2013. The data are tabulated by year of filing and level of

review, as well as program involvement—showing claims for

DI benefits only or concurrent entitlement to DI and SSI benefits. Although both programs use the same definition of disability for adults, eligibility for SSI benefits is further

dependent upon the claimant’s countable assets and income,

which may include DI benefits.

The number of claims forwarded to the DDS for DI disabled

worker benefits grew nearly 30 percent from 1.43 million in

2006 to 1.84 million in 2010. More than two-thirds of this

growth occurred in the years following the Great Recession of

2008, as high levels of unemployment combined with the gen5 For discussions on these topics, the reader is referred to Trends in the Social 

Security and SSI Disability Programs (Muller et al., August 2006), and The 

Social Security Disability Insurance Program—an Analysis (Department of 

Health and Human Services, December 1992).

eral effect of the aging of the baby-boom generation. Since

2010, the number of claims has fallen by roughly 10 percent to

1.64 million in 2013, even though the baby-boom continues to

progress through the peak ages of disability. Opposing economic factors appear to be having a greater effect on applications after 2010. Clearly the number of claims decreases as

people go back to work, but additionally labor force participation rates—which have reached their lowest levels since the

late 1970s as those unable to find work stop looking and drop

out of the labor force—indicate potential claimants may no

longer satisfy the recency-of-work test for DI insured status.

DDS Initial Determinations

As shown in table 1, the number of favorable initial determinations as a percentage of total claims processed steadily

decreased from 37.1% in 2002 to 34.4% in 2006 before rising

back to 37.1% in 2009 then dropping again through 2011.

Determination experience for 2012-13 is still largely incomplete. The baby-boom continues to pass through their 50s

incurring high incidence of musculoskeletal, circulatory, and

neoplastic disorders. The appeal rate of initial denials fluctuates around 55%.

Allowance rates tend to be much lower among those concurrently filing for DI and SSI benefits than those filing for DI

benefits only. This may be due to differences in the composition and economic status of the filers. Concurrent filers tend to

be of lesser means (reflective of the nature of the SSI program)

and are thus more likely affected by changes in the economy.

Often the only alternative to unemployment is to seek aid from

Federal, State, or local programs. Therefore, concurrent filers

may have less severe disabilities, may provide less evidence of

impairment, or are less likely to afford legal representation.

The result is a lower proportion of allowances.

For years with pending workloads at the initial and reconsideration levels, it is likely that the allowance rates will ultimately

be higher than those shown in table 1. This is due to the fact

that denials are processed more quickly than allowances at

these stages, leaving more allowances in pending workloads.

As the workloads are processed and the allowances are realized, the allowance rate rises. The opposite is true at the ODAR

level where favorable decisions are processed more quickly

than unfavorable decisions, leaving more denials in pending

workloads. So it is likely that the ODAR allowance rates will

ultimately be lower than those shown.

DDS Reconsideration

After a less than fully favorable initial determination, a claimant may appeal for a reconsideration at the DDS in all but 10

States (see Miscellaneous Items below for details). Allowance

rates at the reconsideration level have been very consistent.

Although the reconsideration stage is de novo6

 in concept, it is

similar to the initial stage in that disability determination is

mostly a “paper review” process where claimants are rarely

observed by the decision-maker. Assuming some uniformity

among the initial decision-makers, it follows that initial denials

are overturned at reconsideration in only a relatively small proportion of cases appealed.

Appeals Beyond DDS

Claimants wishing to appeal a reconsideration determination—

or initial determination for States without a reconsideration

level—may request a hearing before an ALJ. Since the interpretation of evidence in assessing disability can be highly subjective, overturned decisions at ODAR and beyond occur

frequently. Factors that contribute to the high reversal rate

include:

• A group of decision-makers different from those at the

initial and reconsideration stages;

• Changes in the nature and degree of the claimant’s

impairment over time;

• Use of legal representation and the opportunity to submit

new material evidence supporting the claim; and

• Initial face-to-face contact with decision-makers.

Miscellaneous Items

Because the way in which the disability process operates has

changed over time, we provide some background information

to help interpret the data presented in table 1. First, beginning

in the late 1990s SSA undertook the testing of a variety of

alternative approaches to the disability determination process

with the goal of streamlining the process while still providing

accurate decisions as early in the process as possible. One of

the largest such tests has been referred to as the Prototype

Model. Major features of this model include providing additional authority for the DDS examiners in making initial disability determinations, and the elimination of the

reconsideration step in the appeals process. This test continues

to be run in 10 States representing roughly 25 percent of the

initial disability determination workload. The results shown in

table 1 reflect a mixture of experience combining the standard

decision process with the prototype process, as well as other

smaller test processes.

In the past, public pressure has surfaced in controversial areas.

Changes in regulations, standards, and methods used to determine the severity of a disability—sometimes in response to

legislation or legal suits—have shaped DDS determinations,

ODAR decisions, and SSA policy in general. Major topics for

deliberation have included:

• Mental impairment issues and obesity;

• The amount of leverage given to allegations of pain;

6 That is, a case is reviewed in its entirety and a new decision is made unrelated 

to the initial decision.
6

• Evaluation of musculoskeletal and circulatory disorders;

• Statements by treating physicians in the absence of clinical

evidence; and

• The use of vocational factors in the absence of a single

debilitating impairment.

Other developments in the disability area deserve mention. The

electronic disability (eDIB) process has substantially streamlined the storage and processing of claim data. As of January

2006, all state DDSs had begun using electronic disability folders. Furthermore, beginning in August 2002, claimants have

been able to apply for disability benefits online.

The electronic environment allowed SSA to develop two fasttrack processes to allow expeditious determinations of certain

claims. The quick disability determination (QDD) process uses

a predictive model to identify claims that have a high potential

of allowance, and for which medical evidence can be easily

obtained. Claims are automatically referred from the field

office to the DDS whose aim is to complete the determination

expeditiously.

Similar to QDD but having a slightly less complex “scoring”

criteria is the compassionate allowance (CAL) initiative, which

is designed to quickly identify diseases and conditions that are

highly likely to qualify under the Listing of Impairments even

with minimal, but sufficient, medical information. If the condition does not strictly meet these criteria, it is not designated as

a CAL case. For the rollout of the initiative in the fall of 2008,

fifty conditions were selected to meet the CAL guidelines. The

list has since been expanded to include roughly 225 conditions

such as early-onset Alzheimer’s disease, spinal cord injuries,

and various cancers. A CAL case is identified solely on the

claimant’s allegation of a disease or other medical condition

that appears on the CAL list.

The fast-track initiatives represent a small but growing proportion of total DI worker claims filed. SSA identified 176,200

initial-stage QDD claims in fiscal year 2013, up from 163,600

in FY 2012. CAL claims totaled 10,800 in FY 2013 and 8,200

in FY 2012. Together, fast-track claims made up roughly 11

percent of total DI worker claims in FY 2013.

III. EXPERIENCE OF DISABILITY INCIDENCE AND AWARDS

A. History

Since the payment of the first disability cash benefits in July

1957, the characteristics of the DI program have been shaped

by congressional action, public opinion, and court rulings. Program fundamentals such as the definition of disability, the entitlement process, the level of benefits, and the review process

for current beneficiaries ultimately determine program cost.7

Prior to 1960, the DI program applied only to workers age 50

or older. Prior to 1965, a claimant needed to be permanently

disabled to qualify for benefits. The Social Security Amendments of 1967 (Public Law 90-248) eased the insured status

requirements for persons under age 31, allowing a substantial

number of young beneficiaries to enter the rolls. Then beginning in 1970, program growth began to accelerate for a number

of reasons (see table).

The introduction of the Black Lung program (1970) and the

SSI program (1974), and a severe economic recession

(1974-75) led to hundreds of thousands of new DI claims. In

particular, the SSI program requires applicants to apply for

benefits from other programs—including DI—which may offset SSI benefits. As expediency in processing applications was

naturally given high priority, the fraction of preeffectuation

reviews of DDS initial allowances by the central office fell to

roughly 5 percent in 1972 from 70 percent before 1972. This

resulted in far more effectuations of allowances than would

have otherwise occurred under the more stringent quality control efforts.

The automatic indexing of benefits by the cost-of-living adjustment (COLA) legislated in 1972 contributed to a dramatic

increase in replacement rates. The ratio of annual benefits to

past earnings rose from 50 percent to roughly 70 percent by the

end of the decade. Not only was the agency paying out more in

benefits, but it was thought that high replacement rates made

benefits more “attractive”, thus providing incentive to file

among individuals with a possible qualifying disability. And to

those already on the DI rolls, high replacement rates may have

created disincentive to leave the program and return to work.

Another trend seen in the early 1970s was the greater tendency

of applicants to appeal an unfavorable decision. This significantly increased the number of awards made at the reconsideration and hearings levels, and further contributed to the sharp

increase in awards from 1972-76.

In an effort to bring the cost of disability benefits under control

and stabilize replacement rates, the Social Security Amendments of 1977 (Public Law 95-216) revised the formula for

determining benefits awarded in 1979 and later. Under the new

calculation, the replacement rate for the average earner was

projected to remain stable at around 40 percent. The Social

Security Disability Amendments of 1980 (Public Law 96-265)

also had a significant impact on the DI program. The 1980

amendments introduced a more restrictive limit on the total

monthly amount of Social Security benefits payable on a disabled worker’s account—allowing for higher total family benefits under the old-age program as compared to disability. For

those eligible, this provided incentive to apply for or switch to

old-age benefits in lieu of disability benefits.

In addition, the amendments mandated DDS performance standards and a preeffectuation review of 65 percent initial DDS

allowances. This led the DDSs to give more careful consideration to allowances, and increased the chances of not effectuat7 ing an initially favorable determination. For further discussions on the history of the DI program, the reader is referred 

to the 50th Anniversary of the Social Security Disability Insurance Program 

(Social Security Bulletin Vol. 66, No.3 2005/2006).

The most controversial provision of the 1980 amendments was

the requirement that SSA conduct a continuing disability

review at least every 3 years for beneficiaries whose disability

may not be permanent. The termination of a large number of

beneficiaries (particularly among the mentally impaired) was

met with intense public outcry. A temporary moratorium was

placed on the review of the disability rolls pending a thorough

review of the standards for evaluating certain mental impairments. Although many of those terminated were returned to the

rolls through the appeals process, awards continued to decline

steadily from 1977-82 prompting SSA’s disability determination policies to come under fire through court appeals and class

action suits.

By 1984, DI program policy had undergone another reversal.

In response to the clamor over certain provisions of the 1980

amendments, Congress passed the Social Security Disability

Benefits Reform Act of 1984 (Public Law 98-460). Provisions

of the Act include: revised mental impairment standards;

increased emphasis on treating physician opinion; emphasis

given to the combined effects of multiple impairments in the

absence of a single severe impairment; required proof of medical improvement prior to termination of benefits; and standards

to evaluate pain.

One significant pattern that emerged following the 1984

amendments involved beneficiaries with mental impairments.

The revised listings reduced the weight given to medical factors and put greater emphasis on functional capabilities. By

1988, the proportion of awards for mental impairments had

exceeded 20 percent, roughly twice the proportion experienced

in 1982.

The early 1990s brought a period of rapid growth. The number

of awards to disabled workers over 1991-95 were roughly 48

percent higher than the previous 5-year period (1986-90).

Amidst a recession during which the unemployment rate rose

above 7 percent, mental disorders continued to grow, comprising more than one-quarter of new awards by 1992. In partial

response to this rapid growth, Congress enacted the Contract

with America Advancement Act of 1996 (Public Law 104-121),

which provided for dedicated funding to conduct continuing

disability reviews, and a change in policy for drug addiction

and alcoholism to exclude from eligibility individuals for

whom DA&A is a materially contributing factor in disability.

The Ticket to Work and Work Incentives Improvement Act of

1999 (Public Law 106-170) established the Ticket-to-Work

program, expedited reinstatement provisions for beneficiaries

terminated for returning to work, and increased the period of

extended Medicare coverage for disabled beneficiaries.

There were other notable events that shaped the experience of

disability incidence. In 1999, obesity disorders were eliminated

from the listings. In 2001, SSA discovered several hundred

thousand SSI recipients who, due to incorrect determination of

insured status, potentially became disability insured because of

earnings while receiving SSI, making them eligible for DI benefits. SSA completed processing of this special disability

workload (SDW) in 2011, which on average added roughly

20,000 disabled worker awards per year over the 2003-10

period. In 2002, SSA issued a new musculoskeletal listing. In

2003, the legislated increase in the normal retirement age

began with those attaining age 65 in that year with corresponding increases in DI worker awards at ages greater than 64.

Finally, the large spike in awards in 2008-10 followed by the

decline in 2011-14 reflects the severe economic recession

which began in the first quarter of 2008 and the gradual recovery over the last several years.

B. Diagnostic Group Experience

Table 2A shows the distribution by impairment for awards to

DI disabled workers. The leading diagnostic categories for disability entitlement vary by gender and year of award. The share

of musculoskeletal disorders has increased steadily every year

since 1995 and has been the largest single category of impairment since 2002. Over the 5-year period 2009-13, 33.8 percent

of all awards were attributable to this category—a trend that is

largely explained by demographics. As the baby-boom generation ages through their most disability-prone years, arthritic,

back, and bone disorders become more prevalent.

The apparent jump in the percentage of musculoskeletal

impairments in 1995 can be explained by a change in reporting

method. Prior to 1995, SSA reported the diagnosis of awards

based on the distribution of allowances at the initial level.

Allowances at the appeals level were then assumed to have the

same diagnostic groupings as those at the initial level. Beginning in 1995, the information used to tabulate awards by diagnostic group was expanded to include diagnostic information

from the reconsideration step of the appeals process. In addition, diagnosis information from reconsideration denials was

used to infer a distribution of awards made at the ALJ level and

beyond. These changes revealed a significantly higher proportion of musculoskeletal impairments at the appeals level as can

be observed by the sudden jump in the number of musculoskeletal awards in 1995. The accompanying drop in the percentage

of mental impairments in that year suggests that at least some

of the awards in this category were among those misclassified

under the old reporting method. Beginning in 2003, SSA

developed a more direct way of assigning diagnoses for all

awards regardless of decision level.

Mental impairments rank second in overall percentage of

awards, but have been on a slight downtrend since 2002. Mental disorders were the leading cause of disability among each

sex until 1996 and accounted for 19.5 percent of all awards

over 2009-13. A slight jump in mental disorders occurred over
9

2003-05 due, in part, to the processing of the SDW. Many of

the resulting awards from this misplaced cohort were for individuals diagnosed with a mental disorder.

Among males, circulatory disorders have always been a leading cause of disability, accounting for over 13 percent of

awards over the last 10 years. Neoplastic disorders account for

roughly 10 percent of total awards. Though not shown in the

table, there are nearly four times as many circulatory impairments among those age 50 or older as among those age 35-49;

and three times as many neoplastic disorders for the same age

comparison. Although medical advancements continue against

these impairments, their concentration at the older ages suggests they will continue to significantly impact the DI rolls as

the population ages.

Neoplastic, nervous, and respiratory disorders rank higher

among females, whereas circulatory disorders and injuries rank

higher among males. The impairment listings were changed in

1999 to eliminate awards based solely on obesity, accounting

for the large decline in the percentage of nutritional and metabolic impairments beginning in 2000.

Table 2B shows the distribution by impairment for DI disabled

workers in current-payment status. Similar to table 2A, categories are rank-ordered by average percentage of impairments on

the DI rolls over the 5-year period 2009-13. Due to differences

in mortality and recovery rates among the different types of

impairments, the current pay ranking can be quite different

than the award ranking. Notably, mental disorders maintain the

highest ranking among current pay but were less than one percentage point above musculoskeletal in 2013. And overall,

impairments of the nervous system which are ranked 5th in

awards are 3rd in current pay; and neoplastic impairments

which are 4th in awards drop to 7th in current pay.

C. Award and Incidence Experience

Table 3 shows the number of DI disabled workers awarded

benefits by sex and calendar age—the age attained on the

birthday in the year the individual is awarded benefits—at time

of award, for calendar years 1991-2014. This historical series

is also illustrated in figure 2.

Table 4 shows the associated disabled worker incidence rates,

which are expressed as annual awards per thousand disability

insured not already receiving benefits. Adjusted figures are

based on the age and sex distributions of the exposed population as of 2000.

Tables 3 and 4 are tabulated as of the year the beneficiary is

added to the rolls. However, the year of award may actually be

different from the year of disability onset or entitlement. Factors such as the waiting period, disability determination, and

the claims and appeals process can delay payments for months

or possibly years. So the incidence rates shown are not exactly

representative of true morbidity rates for the stated calendar

years.

The chance of suffering a disability impairment naturally

increases with advancing age. Furthermore, in the disability

determination decision, SSA must consider education, work

experience, and the ability to adjust to other work given the

claimant’s age when the impairment does not meet or equal a

listing. For claimants under age 50, SSA generally does not

consider age to seriously affect the ability to adjust to other

work. For claimants ages 50 to 54, SSA will generally consider

that age will somewhat affect the ability to adjust, while claimants age 55 or older are considered to be significantly affected

in their ability to adjust to other work.

Rates shown in table 4 for ages 60 and older are likely to

understate the true incidence of impairment in the insured population because beginning at age 62, a disabled worker may

elect to receive old-age benefits instead of disability benefits.

This decision is influenced by a number of factors: the chance

for higher maximum family benefits under old-age as compared to disability; avoidance of disability benefit reduction

because of Federal or State workers’ compensation offset8; or

desire to avoid the potentially arduous application process and

possibility of benefit denial.

Age-specific disability incidence among female workers is typically lower than males. However beginning in the late 1990s,

female incidence began to exceed that for males at ages 30-54.

Although both genders were experiencing a general decline in

incidence beginning in the mid-90s, the decline is more pronounced among males. This is likely due to the elimination of

DA&A as a disabling impairment and a sharp decline in HIV

impairments, both of which are predominantly male incidence

categories. Note that the decline in incidence rates among

females did not come from a decline in the number of awards,

but rather from an increase in the exposed population. Over the

10-year period ending in 1996, female labor force participation

among ages 35-54 increased between 3.5-10.0 percentage

points. This contributed significantly to the additional 10.7

million females that became disability insured in that period;

for the same age range, male labor force participation

decreased by roughly 2.0-2.5 percentage points.

Some of the same factors that affect the number of DI applicants can also affect incidence rates. In general, a decline in

incidence between 1975-82 (not shown) is attributable, in part,

to stricter program administration. Following a generally

declining period in incidence from 1983-89, the program experienced a surge in claims beginning in 1990, and incidence

rates rose significantly and remained relatively high through

1995. The economic and political environment of the late

1990s featured robust economic expansion, low unemployment, and restrictions on DA&A and obesity impairments. In

addition, continuing advancements in medical treatment,

employer-sponsored healthcare, and an opportunity to build

wealth in booming investment markets provided incentive to

remain in the labor force and contributed to the decline in

applications and awards during this period.

The sharp increase in incidence rates over 2001-05 represents a

departure from the experience of the late 1990s, which generally showed modest annual declines in the age-sex-adjusted

rate. While the aging of the baby-boom is always recognized as

a factor in program growth, the increase in incidence in 2001 is

likely due in large part to the severe economic contraction

experienced in that year. It is also likely that the special administrative activity previously mentioned also had an impact—

namely, the disability redesign initiatives (late 1990s) and the

identification and processing of the special disability workload

(beginning in 2001).

The legislated increase in NRA beginning with those born in

1938 had an obvious and significant effect on the number of

disability awards to individuals age 65 or older starting in

2003. The increase in NRA may have become an incentive to

seek disability benefits for older workers facing higher actuarial reductions for early retirement.

After a substantial increase over 2008-10—thought to be

attributable to the recession—incidence rates have subsided

over the last few years as the economy recovered. The drop in

incidence over 2011-14 is due to the combination of fewer

awards and a slight uptick in the insured population which put

downward pressure on disability incidence rates. The decline,

however, may have been slightly constrained since many did

not return to work and eventually dropped out of the labor

force. This left the insured population slightly lower than it

otherwise would have been.

Table 5 presents historical conversion and termination data for

disabled workers. Termination experience is discussed in detail

in the next section.

Table 6 shows the number of disabled workers in the currentpayment population, at the end of calendar years 1991-2014.

Other DI beneficiaries may have their benefits suspended for

reasons such as engagement in SGA following completion of a

trial work period, refusal of vocational rehabilitation services,

and imprisonment. Because of the increase in NRA beginning

with individuals born in 1938, DI beneficiaries age 65 or older

appear for the first time in 2003.

As shown in the table below, the number of beneficiaries in

current-payment status and in force (current-pay plus suspensions) began to grow rapidly beginning in the latter half of the

1980s. The expansion continued throughout the 1990s as the

current-pay population increased 68.5 percent. The 2000s saw

a slightly smaller increase of 59.9 percent. The growth in the

in-force population is the difference between awards and terminations, as shown in the table.

IV. EXPERIENCE OF DISABILITY BENEFIT TERMINATION 

A. Background

DI disabled worker beneficiaries stop receiving worker benefits when they die, recover from their disabling condition, or

return to work (disabled workers who remain on the DI rolls

until NRA—currently age 66—are converted to retired worker

status):

• Death. The last month of disability entitlement would be

the month prior to the month of death. Beneficiary death

accounted for 76 percent of total disabled worker

terminations in 2014.

• Recovery. Beneficiaries who have had a medical recovery

or successful, sustained re-entry to the workforce are

removed from the DI rolls. Typically the last month of

disability entitlement would be the second month after the

month of recovery.9

 Recoveries accounted for 22 percent

of total disabled worker terminations in 2014.

Under the Old-Age and Survivors Insurance program (OASI),

a disabled worker benefit is automatically converted to a

retired worker benefit in the month the beneficiary attains

NRA.10 Since conversions are simply a transfer of beneficiaries from the DI Trust Fund, the “conversion” rate is 100 percent for disabled workers reaching NRA. After conversion,

recovery from disability is no longer relevant, and the last

month of DI entitlement is the prior month.

Beginning at age 62, a disabled worker may elect to receive

old-age benefits in lieu of disability benefits. Although most

disabled beneficiaries stay in the DI program until NRA, some

choose to switch. One of the most common reasons is the

receipt of workers’ compensation benefits. WC benefits may

partially or totally offset a DI benefit, but would not affect an

OASI benefit. Another factor is the difference between the

less-generous maximum family benefit payable under the DI

program and the maximum payable under the OASI program.

Recovery from disability occurs when the beneficiary is judged

to no longer meet the definition of disability either because

there is medical improvement, or the individual demonstrates

the ability to engage in SGA. The DDS or the central office

will conduct a continuing disability review (CDR) upon, for

example:

• Coming due of a scheduled CDR;

• Posting of substantial earnings;11 or

• Receipt of vocational rehabilitation reports of medical

improvement.

We mention an important caveat with regard to interpreting termination rates: Absent any changes in the underlying rate of

medical improvement, certain outside factors can impact the

level of CDR activity and, in turn, the disability recovery rates.

These factors include the size of disability backlogs, budget

restrictions, and legislation. Clearly, CDRs can be pursued vigorously only with adequate funding. Less obviously, these factors can affect the composition of the disabled worker

population by influencing the nature of allowances and the

likelihood of recovery.

Exogenous variables can also impact the overall mortality of

the DI rolls. For instance, changes in the way medical impairments are adjudicated, the elimination of DA&A and obesity

from the listings, and a greater number of allowances based on

vocational factors may artificially lower overall disability mortality.

The Social Security Act contains several provisions to encourage beneficiaries to return to work despite their impairment:

• Trial work period; 

• Extended period of eligibility; 

• Extension of Medicare coverage;

• Expedited reinstatement; and

• Waiver of the waiting period.

Trial Work Period (TWP)

The trial work period provision allows the disabled beneficiary

to do substantial work for 9 months—not necessarily consecutive—without losing any benefits. A month is not counted as a

trial work month (“service month”) unless the beneficiary

earns above a specified amount, or for self-employment, works

a specified number of hours.12 Earnings during the service

months are not counted toward SGA, and benefits will continue as long as the beneficiary has not medically recovered.

Note that work performed during a TWP cannot be used as the

basis for determining that disability has ceased.

Extended Period of Eligibility (EPE)

Following the TWP and a 3-month grace period, beneficiaries

who work at the SGA level in any month lose their benefit for

that month. For continued incentive to work, the extended

period of eligibility provision allows the disabled beneficiary

to have benefits reinstated for any month in which work activity falls below the SGA level. The reentitlement period begins

with the month immediately following completion of the TWP

9 Benefits may continue if the individual is currently enrolled in a vocational 

rehabilitation program, or has entered an extended period of eligibility. 10 Switching to old-age benefits prior to normal retirement age is not normally 

considered a conversion. This type of benefit termination would fall in the miscellaneous category.

11 The Ticket to Work Act of 1999 prohibits initiation of a CDR during the 

period that a beneficiary is using a ticket; and under certain circumstances, prohibits the use of work activity as a reason for review. These provisions became 

effective January 1, 2002.

12 In 2014, a service month is counted towards the TWP if earnings for that 

month exceed $770. A self-employed worker can also be charged with a service month if work activity exceeds 80 hours.
12

and ends 36 months later. However, if the beneficiary is not

engaging in SGA when the reentitlement period ends, the provision allows benefits to continue until SGA is performed. Of

course, at any time during the TWP or EPE, if the beneficiary

is found to have medically recovered then all benefits are terminated.

Medicare Coverage

After 24 months of disability entitlement, a beneficiary

becomes eligible for Medicare coverage—regardless of age—

and receives services as long as DI entitlement continues. In

the case of an individual engaging in SGA, coverage is provided throughout the TWP and EPE. Medicare benefits were

further extended through a provision of the Ticket to Work Act

of 1999: effective October 1, 2000, coverage for beneficiaries

who return to work will generally continue for an additional 57

months beyond the EPE.

Expedited Reinstatement (EXR)

The Ticket to Work Act also allows certain previously terminated beneficiaries to request expedited reinstatement of disability benefits in the event of impairment-related cessation of

SGA. The provision provides a safety net for those who successfully return to work and, consequently, lose entitlement to

disability benefits, but then find themselves unable to sustain

the work effort. EXR allows an individual to request reinstatement without filing a new application, and provides up to six

months of provisional (temporary) cash benefits while SSA

conducts a medical review to determine whether the individual

can be reinstated.13 The request for reinstatement must be filed

within 5 years of the termination of disability benefits. EXR

became effective January 1, 2001.

Waiting Period Provisions

Special provisions apply to persons disabled more than once.

Individuals who become disabled within 5 years of the end of a

previous period of disability are not required to satisfy the 5-

month waiting period. In addition, the 24-month waiting period

for Medicare coverage need not be consecutive months and

may be satisfied by combining multiple periods of disability.

B. History

Many variables can affect the rate at which beneficiaries are

terminated from the disability rolls, including:

• Changes in normal retirement age;

• Overall disability mortality;

• CDR activity;

• Technology to enhance the ability to work;

• Advancements in medical treatment;

• Changes in legislation and in regulations.

The Social Security Amendments of 1965 (Public Law 89-97)

modified the definition of disability by replacing the requirement of permanent disability with the requirement that the disability be expected to last at least 12 months. This led to the

entitlement of less seriously impaired claimants and, therefore,

lower mortality rates among the disabled. The 1967 amendments eased the insured status requirements for claimants

under age 31. A growing presence of younger and relatively

healthier beneficiaries on the DI rolls further contributed to the

decline in DI mortality rates.

While mortality rates fell in the early years of the program, the

rates of termination due to recovery generally increased,

largely for the same reasons. With the introduction of government-funded rehabilitation programs, the elimination of the

“permanently disabled” requirement, and the extension of benefits to younger claimants, the recovery rate among beneficiaries rose substantially through the late 1960s and remained

high through the early 1970s. The recovery rate then decreased

rapidly through 1975, due in large part to changes in the

administration of the program. With the introduction of the

Black Lung and SSI programs in the early 1970s, workload

pressures resulted in the suspension or curtailment of some

administrative review procedures. For example, by 1972 the

central office reviewed only 10 percent of the cases in which

expected medical recovery had not been found. By 1976, the

recovery rate started to rise again due, in part, to the return to

pre-1972 levels of 100 percent review of expected medical

recoveries.

The substantial DI program growth in the 1970s created pressure for a more thorough review of the rolls. Under then-current policy, reviews were performed only when the

beneficiary’s condition was expected to improve, or voluntary

reports or posted earnings indicated work activity. As previously discussed, a significant provision of the 1980 amendments required that beneficiaries with non-permanent

impairments be reviewed every 3 years, and permanently disabled beneficiaries be reviewed at intervals determined by the

Commissioner. Using that legislative mandate, the Administration initiated a major review of the disability rolls that resulted

in many terminations because it was determined that recovery

had occurred.

After much public clamor over the new rules, a temporary

moratorium was placed on the review of the rolls.14 This

caused the pendulum to swing the other way. Many persons

were reinstated upon appeal, and legislation in 1984 imposed a

medical improvement standard on the CDR process. The result

was a sharp drop in recoveries through the rest of the decade.

13 The claimant must be under a disability using the medical improvement 

review standards (MIRS) normally used in a CDR. The MIRS requires a 

sequence of evaluation different from that used in intial claims.

14 The moratorium applied to all cases on which an administrative or judicial 

appeal was pending on or after June 7, 1983. All persons claiming benefits 

based on mental impairment disability who received an unfavorable decision 

after March 1, 1981 were permitted to reapply within time constraints, as mandated in 1984 by Public Law 98-460.
13

In the latter part of the 1980s, the agency experienced reductions in both its work force and in administrative funding. By

the early 1990s, without enough staff to handle both new

claims and continuing disability reviews, the agency reduced

the resources it committed to CDRs. Beginning in 1994, the

number of initial claims began to level off and Congress

enacted the Contract With America Advancement Act of 1996

(Public Law 104-121) which included a provision authorizing

the appropriation of funds to be used exclusively to conduct

additional CDRs. The special funding helped the agency complete large numbers of backlogged periodic CDRs and become

current with DI reviews by the end of 2000 and SSI reviews by

the end of 2002. Since 2002, yearly funding constraints have

hampered the timely review of all CDRs coming due based on

matured medical diaries. As a result, SSA again faces a significant CDR backlog without sustained adequate funding.

C. Recent Experience

Table 5 shows a historical series of the number of disabled

worker conversions and terminations, as well as conversion

and termination ratios. Ratios are defined as the number of

conversions or terminations to the average number of beneficiaries during the year. Most terminations occur as a result of

death. With regard to conversions, there is a sharp decrease in

2003, which is the result of the increase in NRA.15 The number

of recoveries can vary considerably. This is sometimes the

result of special circumstances, and may not indicate a change

in the actual rate of recovery. As an example, the spike in

recoveries in 1997 is the result of a provision which eliminated

drug or alcohol addiction as a basis for disability entitlement.

Although categorized in administrative records as “recoveries”, this group of beneficiaries was terminated from the rolls

due to a change in law.

Other is a relatively small category comprised of beneficiaries

terminated for various other reasons such as switching to oldage benefits prior to NRA.16 Reasons for the switch are to

avoid DI benefits that offset WC benefits, or to become entitled

to an OASI family benefit. Notably, the size of this category

was elevated throughout the 2000s due to the “termination” of

a number of past-due-only awards which came out of the SDW

workload. In many instances, only past due DI benefits were

payable because the beneficiary had either died, recovered, or

switched to old-age benefits by the time the case was processed. This type of SDW award was simultaneously counted

as an “other” termination.

Figure 3 shows the distribution of DI disabled worker terminations and conversions, while figure 4 shows these categories

divided by the average number of disabled worker beneficiaries. These ratios have been in a general decline since the early

1980s mostly because of two correlated trends that have developed over the years, namely, the reduction in the average age

of beneficiaries and the increased share of mental and musculoskeletal disorders. Footnote 15 explains the sharp increase in

conversions in 2009; and the leading edge of the baby-boom

(1946-47 birth cohorts) began attaining NRA (66) causing an

uptick in conversions over the last several years.

As shown in the table below, the average age of male disabled

workers in current-payment status steadily declined from 52.8

in 1980 to 49.8 in 1995; over the same period, the proportion of

Figure 3.—Disabled Worker Terminations and 

Conversions, (1990-2014)

(In thousands)

15 This decrease is attributable to the increase in normal retirement age for the 

cohort born in 1938, resulting in the deferral of a portion of old-age conversions from 2003 to 2004. This pattern of deferral continues until NRA is 66 

beginning with those born in 1943 resulting in a sharp increase conversions in 

2009.

the DI rolls made up of beneficiaries aged 35-49 grew from 20

percent to 34 percent, while the proportion of those aged 50-65

fell from 71 percent to 55 percent. Similar trends were experienced among female disabled workers. A higher incidence of

mental disorders led to a decrease in termination rates for mortality and conversion since these beneficiaries are younger and

(physically) healthier on average.

Because of the post-war baby boom, the age pattern was

reversed beginning in 1995. By 2014, the average male disabled worker in current-payment status was 53.7 years old; the

proportion of beneficiaries aged 35-49 declined to 21%; the

proportion of those aged 50-65 grew to 74%. Similar trends

were experienced among females.

As the baby-boom population ages, the DI rolls can be

expected to have greater proportions of beneficiaries with musculoskeletal, circulatory, and neoplastic disorders. Just as progress in medicine has significantly contributed to longer life

expectancy among the general population, it is likely to also

have a considerable impact on some segments of the disability

population.

..

Mortality rates continued to decline in the 1990s particularly

after 1995. Contributing to the decline were the diminishing

impact of HIV-related impairments and the new policy regarding DA&A. Other significant factors include: (1) a shift in the

impairment mix to more musculoskeletal and mental disorders,

which tend to be less life-threatening than circulatory or neoplastic disorders; (2) advancements in cancer treatments; and

(3) a shift in the age mix to older disabled workers, whose

determinations are often based on vocational factors rather

than meeting a listing severity. Over the decade of the 2000s

the gross death rate continued to decline to roughly 33 deaths

per thousand males and 24 deaths per thousand females.

D. Actuarial Analysis—Death (2006-10)

Tables 7A-7C show the probability of death for male and

female DI disabled workers by age at entitlement to disability

benefits, and duration—measured in completed years of disability entitlement. Data reflect the actual experience of the DI

rolls from January 1, 2006 through December 31, 2010. The

methods used in table construction and graduation are detailed

in the appendix.

Mortality among disabled workers generally increases with

entitlement age, albeit this trend can be heavily influenced by

the severity-mix of disorders at different ages. Also, for any

given entitlement age, the probability of death is greatest

during the first year of entitlement, then decreases dramatically

during the second and third years of entitlement. Death probabilities tend to level off sometime around the fifth or sixth

duration for males, and the third or fourth duration for females.

For older entitlement ages, mortality trends upward in the later

durations because of the effect of age. The sex differential in

mortality in the disabled worker population is similar to that of

the general population: mortality rates among male disabled

workers are higher than female disabled workers for most

attained ages. In the appendix we discuss how certain provisions in the law—such as the waiting period and the conversion to old-age benefits—affect the tabulation of mortality.

An analysis of broad age categories may explain some of the

trends and characteristics of disability mortality. As of 2012,

the top disorders for male awards under age 35 are mental

(52%), musculoskeletal (13%), and nervous (10%). Following

the predominant mental and musculoskeletal categories (combined 53%), ages 35-49 show a mix of circulatory (9%), nervous (9%), and neoplastic (7%) impairments. Ages 50 or older

show the highest concentration of musculoskeletal (38%),

along with considerable increases in circulatory (17%) and

neoplastic (11%) disorders; though still an important category,

the prevalence of mental impairments (9%) has declined considerably since the younger age groups.

Female trends are comparable to those of disabled males

except for several differences in leading impairment categories. As of 2012, disabled females under age 35 show the highest concentration of mental (46%), musculoskeletal (16%), and

nervous (12%) disorders. Ages 35-49 continue to show high

incidence of mental and nervous impairments, along with large

increases in musculoskeletal (31%) and neoplastic (9%) disorders. Ages 50 or older show the highest prevalence of musculoskeletal (44%), mental (12%), and neoplastic (11%) awards.

Disability mortality in the 5-year period covered by this study

(2006-10) is lower than the previous 5-year period for 90 percent of all age-sex categories.17 Among males, mortality in the

more recent period is, on average, 8% lower—most attained

ages experienced 5-15% reductions from the earlier period,

while some younger entitlement ages may have experienced

20-30% reductions. Interestingly, the largest mortality

improvements were in the first year of disability—duration 0

in the tables—where there was an average reduction of over

12%. Males at entitlement ages 40-49 experienced 10% reduction in mortality and ages 50-59 experienced 12% reduction in

mortality. Disabled females experienced similar reductions—

mortality in the more recent period is, on average, 10% lower,

and there were average reductions of 10% at duration 0, 9% at

ages 40-49, and 13% at ages 50-59.

The improvements are likely due to medical progress as well as

the changing impairment mix of the rolls. The proportion of

musculoskeletal disorders continues to increase while mental

disorders are down slightly; together they make up 60 percent

of total beneficiaries in current pay status over 2006-10 versus

58 percent for the prior 5-year period. Current pay beneficiaries with circulatory disorders fell to 9.0 percent from 9.9 percent. On average, musculoskeletal and mental disorders exhibit

lower mortality than most other diagnostic groups, whereas circulatory disorders rank among the highest.

Tables 8A-8C show an assumed number of beneficiaries with

benefit continuance over time for cohorts becoming entitled at

various ages. These tables are based on the probabilities of

death shown in tables 7A-7C. Continuance tables simplify the

process of calculating the probability of continuing on the rolls

for a given number of years. See the appendix for details on

table construction and usage. In this context, continuance

refers to beneficiaries who have not died and remain on the DI

rolls.

Tables 9A-9C show the expected future time on the combined

DI and OASI rolls—excluding the possibility of recovery—for

disabled workers who have not yet died. Similar to the retired

population, disabled females have a longer experience of continuance than males. Expected time on the rolls has a tendency

to be higher in the second year of entitlement than in the first

year of entitlement for older entitlement ages because of higher

mortality during the first year on the rolls.

Tables 10A-10C show the absolute rate of death per thousand

entitled disabled workers. These rates are derived from the

probabilities of death shown in tables 7A-7C. In general, absolute rates consider only the effect of a single decrement in a

multiple-decrement environment. For example, the absolute

rate of death is disaggregated from the rate of recovery and

reflects the rate of survival and ultimate termination under

death only. The appendix gives further details.

Tables 11 and 12 show the aggregate probability of death and

expected future time on the combined DI and OASI rolls

(excluding the possibility of recovery), by entitlement and

attained age. Probabilities are based on aggregate counts of

exposure and deaths across all durations. They represent the

average probability of death within the next year for disability

beneficiaries who became entitled at a particular age (table 11),

or who have attained a particular age (table 12). Similarly,

expected future time represents the average number of years a

beneficiary will remain alive and on the rolls, as of a particular

entitlement age or attained age. Values are exposure-weighted

averages of the select-and-ultimate future times shown in

tables 9A-9C and may be used as a general indication of the

overall average lifetime of groups of disabled beneficiaries

who share a particular entitlement or attained age. 17 Findings are based on comparisons with disability mortality tabulated for the 

period 2001-05 in Actuarial Study No. 122 Social Security Disability Insurance 

Program Worker Experience (Zayatz, May 2011).

Table 13 shows the aggregate probability of death and

expected future time on the combined DI and OASI rolls

(excluding the possibility of recovery), as of a particular duration. Probabilities are based on aggregate counts of exposure

and deaths across all entitlement ages, and represent the average probability of death within the next year. Similarly,

expected future time represents the average number of years a

beneficiary will remain alive and on the rolls, given the completed number of years of disability entitlement.

E. Actuarial Analysis—Recovery (2006-10)

Tables 14A-14B show the probability of recovery for male and

female DI disabled workers by age at entitlement to disability

benefits, and duration. In general, annual probabilities of

recovery decline with advancing entitlement age. For any particular entitlement age, the probability of recovery exhibits a

bimodal distribution that tends to peak during the second year

of entitlement and then peaks again—frequently at a higher

level—in the fifth year of entitlement. This pattern likely

reflects the scheduling of Continuing Disability Reviews.

Where medical improvement is expected (MIE), the review is

scheduled for 6 to 24 months following the most recent disability decision. Where medical improvement is possible (MIP) but

less likely to occur within the first 2 years, the review is scheduled for 36 months later. Where medical improvement is not

expected (MINE), the review is scheduled between 5 and 7

years later.

According to data for title 2 disabled workers over the period

2006-10:

• Roughly 18% of full medical reviews fall in the MIE

category and roughly 7.6% of these reviews ultimately

result in cessation of benefits. This helps explain the first

peak in recoveries.

• Roughly 75% of full medical reviews fall in the MIP

category and roughly 5.5% of these reviews ultimately

result in cessation of benefits. This helps explain the

second peak in recoveries.

• The remaining 7 percent of full medical reviews fall in the

MINE category and roughly 3.3% of these reviews

ultimately result in cessation of benefits.

The probability of recovery for females is lower than males for

almost 2/3 of attained ages (and 3/4 of attained ages less than

50). This is due, in part, to differences in the mix of impairments among men and women. Over the period 2006-10, 38%

of awards to females under age 50 were for mental disorders,

while awards to females over age 50 included 39% musculoskeletal and 21% circulatory and neoplastic. By comparison,

36% of awards to males under age 50 were for mental disorders, while awards to males over age 50 included 33% musculoskeletal and 29% circulatory and neoplastic. We think that

these types of impairments result in lower-than-average recovery rates—and longer expected times on the DI rolls—among

females as compared to males.

The probability of recovery in the 5-year period covered by

this study (2006-10) is lower than the previous 5-year period

for almost 90 percent of all age-sex categories.18 Among

males, the chance of recovery in the more recent period is, on

average, 28% lower—most attained ages experienced 15-40%

percent reductions from the earlier period, while some younger

entitlement ages experienced 50% reductions or more. The

largest declines in the rate of recovery occurred in the fourth

year of disability—duration 3 in the tables—which saw an

average reduction of over 55%. Entitlement ages 30-39 experienced 28% reduction and 40-49 experienced 22% reduction in

recovery rates. Disabled females experienced similar reductions in recovery compared with the earlier period—overall

female recovery rates are 26% lower, and there were average

reductions of 54% at duration 3, 24% at ages 30-39, and 23%

at ages 40-49.

Presumably the main reason for the decline in recovery rates is

the reduction in funding for CDRs from the first half of the

decade to the second half. In fact there were 1.39 million initial

DDS decisions of medical CDRs conducted in the 2001-05

period, but only 567,000 in the 2006-10 period.19

Tables 15A-15B show an assumed number of beneficiaries

with benefit continuance over time for cohorts becoming entitled at various ages. These tables are based on the probabilities

of recovery shown in tables 14A-14B. In this context, continuance refers to beneficiaries who have not recovered and remain

on the DI rolls.

Tables 16A-16B show the expected future time on the DI

rolls—excluding the possibility of death—for disabled workers

who have not yet recovered. The tables are discontinued at

NRA since recovery is no longer tracked.

Tables 17A-17B show the absolute rate of recovery per thousand entitled disabled workers. These rates are derived from

the probabilities of recovery shown in tables 14A-14B. The

appendix gives details on the derivation of these rates.

Tables 18 and 19 show the aggregate probability of recovery

and expected future time on the DI rolls (excluding the possibility of death), by entitlement and attained age. Probabilities

are based on aggregate counts of exposure and recoveries

across all durations. They represent the average probability of

18 Based on comparisons with disability recovery probabilities in Actuarial

Continuing Disability Reviews (2012).
17

recovery within the next year for disability beneficiaries who

became entitled at a particular age (table 18), or who have

attained a particular age (table 19). Similarly, expected future

time represents the average number of years a beneficiary will

remain on the DI rolls—up to NRA—for a particular entitlement age or attained age. These values are exposure-weighted

averages of the values shown in tables 16A-16B.

Table 20 shows the aggregate probability of recovery and

expected future time on the DI rolls (excluding the possibility

of death), as of a particular duration. Probabilities are based on

aggregate counts of exposure and recoveries across all entitlement ages, and represent the average probability of recovery

within the next year. Similarly, expected future time represents

the average number of years a beneficiary will remain on the

DI rolls—up to NRA—given the completed number of years of

disability entitlement.

F. Actuarial Analysis—Death or Recovery (2006-10)

Tables 21A-21B show the probability of death or recovery for

male and female disabled workers, by entitlement age and

duration. Values are the sum of the death probabilities shown

in tables 7A-7B and recovery probabilities shown in tables

14A-14B.

Tables 22A-22C show an assumed number of beneficiaries

with benefit continuance over time for cohorts becoming entitled at various ages. In this context, continuance refers to beneficiaries who have neither died nor recovered and remain on

the DI or OASI rolls. Beneficiaries continue to be followed

until death, even after their disability benefits are converted to

retirement benefits.

Tables 23A-23B show the expected future time on the combined DI and OASI rolls for disabled workers who have neither

died or recovered. Values are based on the continuance experience shown in tables 22A-22C.

Tables 24A-24B show the expected future time on the DI rolls

for disabled workers who have neither died or recovered. Values are based on the continuance experience shown in tables

22A-22B and do not reflect entitlement beyond conversion to

retirement benefits.

Tables 25 and 26 show the aggregate probability of death or

recovery and the expected future time on the beneficiary rolls,

by entitlement and attained age. The values represent the average probability of benefit termination due to death or recovery

within the next year for beneficiaries who became entitled at a

particular age (table 25), or who have attained a particular age

(table 26). Expected future time on the OASDI rolls represents

the average number of years of combined entitlement for those

originally entitled to disability benefits, and are exposureweighted averages of expected time on the rolls shown in

tables 23A-23B. Expected future time on the DI rolls represents the average number of years of disability entitlement,

and are exposure-weighted averages of expected time on the

DI rolls shown in tables 24A-24B.

Table 27 shows the aggregate probability of death or recovery

and the expected future time on the beneficiary rolls, as of a

particular duration. The values represent the average probability of benefit termination due to death or recovery within the

next year for beneficiaries who have neither died nor recovered

as of the stated number of years of entitlement. As in table 26,

aggregate expected times are shown for both OASDI combined

entitlement and DI entitlement only.

G. Annuity Tables

Tables 28A-31D show the present value of a stream of payments of $1 to a disabled worker, by entitlement age. The various scenarios are based on combinations of several parameters:

(a) the frequency of payments—annually or monthly; (b) the

timing of payments—beginning (annuity-due) or end (annuityimmediate) of each period; and (c) the duration of payments—

for life or up to age 66. Payments are discounted at various

annual effective interest rates. Tables 28A-29D recognize only

the risk of death and payments may continue beyond NRA,

thus they use continuance experience shown in tables 8A-8C.

Tables 30A-31D recognize the possibility of both death and

recovery and payments are made up until age 66 (NRA), thus

they use continuance experience shown in tables 22A-22B.

The appendix gives details of the table construction and its

usage.

Death Experience

by Entitlement Age and Duration

(2006-10)
.
27

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration t represents the probability of death—in a multiple-decrement environment—during the (t+1) year of entitlement for those

originally entitled to disability benefits at entl age [x] who have attained age [x]+t.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

table 7C for attained ages beyond age 75.

4. Results have been graduated using the Whittaker-Henderson Type B two-dimensional method.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration t represents the probability of death—in a multiple-decrement environment—during the (t+1) year of entitlement for those

originally entitled to disability benefits at entl age [x] who have attained age [x]+t.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

table 7C for attained ages beyond age 75.

4. Results have been graduated using the Whittaker-Henderson Type B two-dimensional method.

Notes:

1. The value at attained age x represents the probability of death within one year for those originally entitled

to disability benefits who have attained that particular age. Experience after NRA reflects workers who

remain on the DI rolls until NRA and then convert to the OASI rolls thereafter, as well as workers who

voluntarily switch from DI to OASI prior to NRA.

2. Results have been blended based on attributes from general population mortality for calendar year 2000.

Values are an extension of the ultimate column of tables 7A and 7B.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration 0 represents an assumed number of lives originally entitled to disability benefits at entl age [x]; the value at duration

t > 0 represents the number of lives from the original who have not died and remain on the rolls as of attained age [x]+t. Lives are decremented using

probabilities from table 7B. 

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

Notes:

1. The value at attained age x represents the number of lives remaining from those originally entitled to

disability benefits who have attained that particular age. Experience after NRA reflects workers who remain

on the DI rolls until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily

switch from DI to OASI prior to NRA.

2. Lives are decremented using probabilities from table 7C. Values are an extension of the ultimate column

of tables 8A and 8B.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration t represents the average number of future years a beneficiary will remain on the combined DI and OASI rolls for those originally

entitled to disability benefits at entl age [x] who have not died as of attained age [x]+t. Values are based on continuance experience from tables 8A and 8C.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

table 9C for attained ages beyond age 75.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration t represents the average number of future years a beneficiary will remain on the combined DI and OASI rolls for those originally

entitled to disability benefits at entl age [x] who have not died as of attained age [x]+t. Values are based on continuance experience from tables 8B and 8C.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

table 9C for attained ages beyond age 75.

Notes:

1. The value at attained age x represents the average number of future years a beneficiary will remain on the

OASI rolls for those originally entitled to disability benefits who have attained that particular age.

Experience after NRA reflects workers who remain on the DI rolls until NRA and then convert to the OASI

rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. Values are based on continuance experience from table 8C and are an extension of the ultimate column of

tables 9A and 9B.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration t represents the number of deaths per thousand during the (t+1) year of entitlement for those originally entitled to disability

benefits at entl age [x] who have not died as of attained age [x]+t. Rates are derived from death probabilities shown in table 7A and recovery probabilities shown

in table 14A. See appendix for details.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration t represents the number of deaths per thousand during the (t+1) year of entitlement for those originally entitled to disability

benefits at entl age [x] who have not died as of attained age [x]+t. Rates are derived from death probabilities shown in table 7B and recovery probabilities shown

in table 14B. See appendix for details.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

table 10C for attained ages beyond age 75.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits.

2. Probability of death at entl age [x] represents the average probability of death within one year for disability

beneficiaries who became entitled at that particular age. Values are based on aggregate counts of exposure and

deaths across all durations, and have been graduated using Whittaker-Henderson method.

3. Future time on OASDI rolls at entl age [x] represents the aggregate expected number of years on the

combined DI and OASI rolls for disability beneficiaries who became entitled at that particular age. Values are

exposure-weighted averages of expected future times across all durations from tables 9A, 9B, and 9C.

Experience reflects continuing entitlement after NRA.

Notes:

1. Attained age calculated as sum of entitlement age and duration.

2. Probability of death at attained age x represents the average probability of death within one year for

disability beneficiaries who have attained that particular age. Values are based on aggregate counts of exposure

and deaths across all durations, and have been graduated using Whittaker-Henderson method. See table 7C for

attained ages beyond age 75.

3. Future time on OASDI rolls at attained age x represents the aggregate expected number of years on the

combined DI and OASI rolls for disability beneficiaries who have attained that particular age. Values are

exposure-weighted averages of expected future times across all durations from tables 9A and 9B. See table 9C

for attained ages beyond age 75. Experience reflects continuing entitlement after NRA.

Notes:

1. Duration measured in years since entitlement.

2. Probability of death at duration t represents the average probability of death during the (t+1) year of

entitlement to benefits. Values are based on aggregate counts of exposure and deaths across all entitlement

ages. Results have been graduated using Whittaker-Henderson method, and blended to reflect mortality trends

established in table 7C.

3. Future time on OASDI rolls at duration t represents the aggregate expected number of years on the combined

DI and OASI rolls for disability beneficiaries who have not died after t years. Values are exposure-weighted

averages of expected future times across all ages from tables 9A, 9B, and 9C. Experience reflects continuing

entitlement after NRA.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Recovery is not considered beyond NRA.

2. The value at duration t represents the probability of recovery while on the DI rolls—in a multiple-decrement environment—during the (t+1) year of

entitlement for those originally entitled to disability benefits at entl age [x] who have attained age [x]+t.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement.

4. Results have been graduated using the Whittaker-Henderson Type B two-dimensional method.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Recovery is not considered beyond NRA.

2. The value at duration t represents the probability of recovery while on the DI rolls—in a multiple-decrement environment—during the (t+1) year of

entitlement for those originally entitled to disability benefits at entl age [x] who have attained age [x]+t.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement.

4. Results have been graduated using the Whittaker-Henderson Type B two-dimensional method.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Recovery is not considered beyond NRA.

2. The value at duration 0 represents an assumed number of lives originally entitled to disability benefits at entl age [x]; the value at duration

t > 0 represents the number of lives from the original who have not recovered and remain on the rolls as of attained age [x]+t. Lives are decremented using

probabilities from table 14B. 

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Recovery is not considered beyond NRA.

2. The value at duration t represents the average number of future years a beneficiary will remain on the DI rolls for those originally entitled to disability

benefits at entl age [x] who have not recovered as of attained age [x]+t. Values are based on continuance experience from table 15A.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement.

The average future years on the DI rolls for attained ages 62 and older are adjusted to reflect less than a full year of DI exposure after attaining age 65 for birth

cohorts 1938-42 to account for the phased-in increase in NRA from 65 to 66.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Recovery is not considered beyond NRA.

2. The value at duration t represents the average number of future years a beneficiary will remain on the DI rolls for those originally entitled to disability

benefits at entl age [x] who have not recovered as of attained age [x]+t. Values are based on continuance experience from table 15B.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement.

The average future years on the DI rolls for attained ages 62 and older are adjusted to reflect less than a full year of DI exposure after attaining age 65 for birth

cohorts 1938-42 to account for the phased-in increase in NRA from 65 to 66.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Recovery is not considered beyond NRA.

2. The value at duration t represents the number of recoveries per thousand during the (t+1) year of entitlement for those originally entitled to disability

benefits at entl age [x] who have attained age [x]+t. Rates are derived from death probabilities shown in table 7A and recovery probabilities shown in table 14A.

See appendix for details.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Recovery is not considered beyond NRA.

2. The value at duration t represents the number of recoveries per thousand during the (t+1) year of entitlement for those originally entitled to disability

benefits at entl age [x] who have attained age [x]+t. Rates are derived from death probabilities shown in table 7B and recovery probabilities shown in table 14B.

See appendix for details.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits.

2. Probability of recovery at entl age [x] represents the average probability of recovery within one year for

disability beneficiaries who became entitled at that particular age. Values are based on aggregate counts of

exposure and recoveries across all durations, and have been graduated using Whittaker-Henderson method.

3. Future time on DI rolls at entl age [x] represents the aggregate expected number of years on the DI rolls for

disability beneficiaries who became entitled at that particular age. Values are exposure-weighted averages of

expected future times across all durations from tables 16A and 16B. Experience does not reflect continuing

entitlement after NRA.

Notes:

1. Attained age calculated as sum of entitlement age and duration.

2. Probability of recovery at attained age x represents the average probability of recovery within one year for

disability beneficiaries who have attained that particular age. Values are based on aggregate counts of exposure

and recoveries across all durations, and have been graduated using Whittaker-Henderson method.

3. Future time on DI rolls at attained age x represents the aggregate expected number of years on the DI rolls

for disability beneficiaries who have attained that particular age. Values are exposure-weighted averages of

expected future times across all durations from tables 16A and 16B. Experience does not reflect continuing

entitlement after NRA.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration t represents the probability of death or recovery from disability during the (t+1) year of entitlement for those originally entitled

to benefits at entl age [x] who have attained age [x]+t. Values are derived from death probabilities (table 7A) and recovery probabilities (table 14A).

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

table 7C for death probabilities beyond attained age 75.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration t represents the probability of death or recovery from disability during the (t+1) year of entitlement for those originally entitled

to benefits at entl age [x] who have attained age [x]+t. Values are derived from death probabilities (table 7B) and recovery probabilities (table 14B).

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

table 7C for death probabilities beyond attained age 75.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration 0 represents an assumed number of lives originally entitled to disability benefits at entl age [x]; the value at duration

t > 0 represents the number of lives from the original who have not died or recovered and remain on the rolls as of attained age [x]+t. Lives are decremented

using probabilities from table 21B.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

table 22C for attained ages beyond age 75.

Notes:

1. The value at attained age x represents the number of lives remaining from those originally entitled to

disability benefits who have attained that particular age. Experience after NRA reflects workers who remain

on the DI rolls until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily

switch from DI to OASI prior to NRA.

2. Lives are decremented using probabilities from table 7C. Values are an extension of the ultimate column

of tables 22A and 22B.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Experience after NRA reflects workers who remain on the DI rolls

until NRA and then convert to the OASI rolls thereafter, as well as workers who voluntarily switch from DI to OASI prior to NRA.

2. The value at duration t represents the average number of future years a beneficiary will remain on the combined DI and OASI rolls for those originally

entitled to disability benefits at entl age [x] who have not died or recovered as of attained age [x]+t. Values are based on continuance experience from tables 22A

and 22C.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement. See

table 9C for attained ages beyond age 75.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits. Duration measured in years since entitlement. Attained age calculated as sum of entl age

and duration. Results do not include auxiliary beneficiaries payable under the DI program. Death or recovery are not considered beyond NRA.

2. The value at duration t represents the average number of future years a beneficiary will remain on the DI rolls for those originally entitled to disability

benefits at entl age [x] who have not died or recovered as of attained age [x]+t. Values are based on continuance experience from table 22A, however, entitlement

is not considered after conversion to old-age benefits.

3. Select-and-ultimate table is read across the row for 0-10 years of entitlement, and down the last (ultimate) column for 10 or more years of entitlement.

The average future years on the DI rolls for attained ages 62 and older are adjusted to reflect less than a full year of DI exposure after attaining age 65 for birth

cohorts 1938-42 to account for the phased-in increase in NRA from 65 to 66.

Notes:

1. Entl age denotes age last birthday at entitlement to disability benefits.

2. Probability of death or recovery at entl age [x] represents the average probability of death or recovery within one year for disability

beneficiaries who became entitled at that particular age. Values are derived from the average death probabilities shown in table 11 and the

average recovery probabilities shown in table 18.

3. Future time on OASDI rolls at entl age [x] represents the aggregate expected number of years on the combined DI and OASI rolls for disability

beneficiaries who became entitled at that particular age. Values are exposure-weighted averages of expected future times across all durations

from tables 23A, 23B and 9C. Experience reflects continuing entitlement after NRA.

4. Future time on DI rolls at entl age [x] represents the aggregate expected number of years on the DI rolls for disability beneficiaries who

became entitled at that particular age. Values are exposure-weighted averages of expected future times across all durations from tables 24A and

24B. Experience does not reflect continuing entitlement after NRA.

Notes:

1. Duration measured in years since entitlement.

2. Probability of death or recovery at duration t represents the average probability of death or recovery during the (t+1) year of entitlement to

benefits. Values are derived from the average death probabilities shown in table 13 and the average recovery probabilities shown in table 20.

3. Future time on OASDI rolls at duration t represents the aggregate expected number of years on the combined DI and OASI rolls for disability

beneficiaries who have not died or recovered after t years. Values are exposure-weighted averages of expected future times across all ages from

tables 23A, 23B and 9C. Experience reflects continuing entitlement after NRA.

4. Future time on DI rolls at duration t represents the aggregate expected number of years on the DI rolls for disability beneficiaries who have not

died or recovered after t years. Values are exposure-weighted averages of expected future times across all ages from tables 24A and 24B.

Experience does not reflect continuing entitlement after NRA.

V. STUDY POPULATION AND METHODS

A. Overview

This study is based on over 14.5 million records of Social

Security Disability Insurance (DI) worker beneficiaries drawn

from the administration’s Master Beneficiary Record (MBR) in

February 2014. The 5-year observation period covers January

1, 2006 through December 31, 2010. These records provide

29.4 million life-years of exposure for males and 25.5 million

life-years of exposure for females. The primary variables of

interest are: the reason for termination of benefits, the age at

entitlement, the number of years since entitlement, and sex of

the beneficiary.

The main reasons that disabled workers stop receiving disability benefits are:

• Conversion to old-age benefits;

• Death of the beneficiary; and

• Recovery—includes medical recovery or return to SGA.

There are a small number of terminations due to other reasons

that are not explicitly examined. The table below provides the

number of deaths and recoveries observed during the observation period. To a certain extent, this study traverses the activity

of the OASI rolls by tracking deaths of former disabled workers who converted to old-age worker benefits either by choice

or upon attaining normal retirement age.

Source: MBR database as of February 2014. Refer to table 5 in section IV for

the number of conversions and terminations due to other reasons. The number

of deaths and recoveries shown above will differ from those found in table 5

due to differences in statistical methods used in tabulations. The number of

deaths will be dramatically different as they include a substantial number from

the OASI rolls.

B. Data Considerations

Mortality experience of the DI rolls is affected by several

unique circumstances. Since experience begins with entitlement, deaths that occur during the 5-month waiting period

prior to entitlement to DI benefits are outside the scope of this

study. It is also true that a claimant may die in the first month

of entitlement, or before final disposition of the disability

claim—in which case only retroactive disability benefits may

be payable. These cases are handled by counting the death, but

crediting no exposure on the record.

Participants in this study may have multiple periods of disability under examination. There are instances, however, where

very little time passes between periods of entitlement for reasons such as a failed work-attempt, an expedited reinstatement,

or a successful appeal of an unfavorable CDR. So although a

recovery has occurred, the beneficiary may be back on the rolls

shortly thereafter. Also, it is not uncommon for beneficiaries

with multiple periods of disability to become re-entitled under

the same or a similar impairment. Although re-entering the

rolls at a different entitlement age, such individuals may, in

essence, recover from the same disability more than once.

C. Data Selection

After various screenings and checks, data for up to five separate periods of disability were included for the following beneficiaries in the final overall sample:

• Workers entitled to disability benefits at some time during

the observation period;

• Workers entitled to old-age benefits at some time during

the observation period who are former disabled-worker

beneficiaries with no break between DI and OASI

entitlement.

Records of persons from the Special Disability Workload

(SDW) were excluded from this study. This group of SSI recipients who are potentially eligible for DI benefits due to previously unrecognized disability-insured status caused a

supplemental increase in awards over the period 2001-10. In

most instances, entitlement is retroactive to well before the

date of final review. However, due to the guidelines established

for processing the workload, completed SDW cases represent a

biased sample of records and were therefore eliminated.

D. Methods

The availability of complete data on each person in the study

(sex, date of birth, date of entitlement, date of decrement, and

cause of decrement) allows for direct estimation of the multiple-decrement probabilities , where represents the cause

of decrement. Each unit age interval represents one

life-year of potential exposure. For each interval that an individual is under observation, the person enters the interval at

age , and is scheduled to exit the interval at age

. Note that except for instances where

the beginning of the observation period falls within the age

interval. Similarly except for instances where the end of

the observation period falls within the interval. Clearly, is

the amount of time that the person is scheduled to be exposed

to the risks of decrement. The total scheduled exposure for an

interval is obtained by summing over all persons.20

As an example of the above method, consider a disabled

worker entering an interval at age . The scheduled ending

age, , is established for the interval under the expectation

that the person will either survive to the end , or exit the

study due to the end of the observation period . Scheduled exposure is then credited as follows: if the person survives

to the end of the interval, then exposure is credited from 

to ; if the person dies or recovers during the interval,

exposure is still credited from to ;21 if the observation period ends during the interval, then exposure is credited

from to . A modification is made to the way exposure is calculated for determining recovery probabilities. Since

recovery is no longer a consideration after converting to oldage benefits, exposure is credited only up until the month of

the switch.

Multiple-decrement probabilities are calculated by dividing the

observed number of deaths or recoveries in an interval by the

aggregate scheduled exposure for that interval. As will be discussed later, single-decrement (absolute) rates can be derived

from these probabilities by using a constant force assumption

for the distribution of decrement within the interval.22

E. Entitlement Age and Exposure

This is a select-and-ultimate study with a 10-year select period

implying that the risks of decrement for beneficiaries 10 or

more years beyond entitlement are no longer a function of entitlement age, but a function of attained age only.

Rarely does entitlement to disability benefits occur on a beneficiary’s birthday. To facilitate exposure calculations, insuring

age and the corresponding insuring date of birth may be substituted for the actual age at entitlement and the actual date of

birth, respectively. This study uses an insuring age that is set at

the beneficiary’s age last birthday as of entitlement. As an

example:

Date of entitlement: February 1, 2010

Date of birth: July 10, 1965

Actual age at entitlement: 44 years, 206 days

Insuring age: 44 years

Insuring date of birth: February 1, 1966

Use of the integral insuring age at entitlement ensures that subsequent durations begin on the beneficiary’s birthday. This is

true whether the participant enters the study during the observation period, or is already part of the entitlement group when

the observation period opens.

F. Duration and Graduation

The unit intervals for which a beneficiary is under observation

are called durations. For each entitlement age and duration

, the quantity represents the amount of exposure contributed to the observation interval . For

durations beyond the 10-year select period, exposure is credited to the appropriate attained age interval .

The select-and-ultimate multiple-decrement probabilities are

graduated using the two-dimensional Whittaker-Henderson

Type B method.23 The horizontal and vertical smoothing coefficients were chosen to obtain some degree of smoothness

within individual durations (columns) as well as within entitlement ages (rows), without deviating much from the original

estimates.

G. Continuance Tables

Continuance tables 8A-8C are constructed from select-andultimate death probabilities. The values are

first calculated for entitlement age , using a radix of

100,000. This step determines values for the ultimate period of

the table and attained ages greater than 75. Values for entitlement ages are then derived from the ultimate values

by working backwards. For example, is determined from

 using the survival probabilities of the select period for

the given entitlement age. The value for is the number of

lives remaining from the original who have attained age

. The number alive at any given entitlement or attained

age is not an actual count of disability beneficiaries, but is the

product of combining probabilities with an arbitrary radix.

Continuance tables for the decrement of recovery (15A-15B)

and the combined decrements of death and recovery (22A22C) are constructed in the same manner. Since recovery is no

longer considered after attaining normal retirement age, tables

15A-15B are truncated after attained age 65.24

The continuance tables are read across the row, or select

period, for 0-10 years since entitlement, then down the last column, or ultimate period for 10 or more years since entitlement.

The example below uses numbers from table 8A for male disabled beneficiaries becoming entitled at age 50.

21All persons are expected to survive to the end of the interval, even those who 

wind up dying or recovering at age . The important point is that 

decrement was not expected so the scheduled ending age is set at . 22For a complete discussion on multiple-decrement probabilities, the associated single-decrement rates, and construction of the select-and-ultimate multiple-decrement tables found in this study, the reader is referred to Actuarial 

Mathematics (Bowers et al. 1997).

age 66 (1944 birth cohort). See chart in section I.

H. Expected Future Time on Rolls

Tables showing expected future time on the rolls are derived

from the continuance functions described above using the basic

actuarial principles found in any standard actuarial text on life

contingencies. We also present in this study the results of

aggregating over duration, by entitlement age (see tables 11,

18, and 25) or attained age (see tables 12, 19, and 26).

Expected future time for a specific entitlement age is an exposure-weighted average of the expected future time at each

duration of that age. This differs from the expected future time

for a specific attained age, which is an exposure-weighted

average of the expected future time at various durations of various entitlement ages.

For example, expected future time for entitlement age 40 is a

weighted average of the expected times across the select row

and down the ultimate column. Each cell represents a different

attained age. In contrast, expected future time for attained age

40 is a weighted average of the expected times for a 40-yearold at duration 0, a 39-year-old at duration 1,...and a 16-yearold at duration 24—all of whom are attained age 40.

I. Probabilities and Absolute Rates

In this study we present probabilities of decrement for two of

the several decrements affecting the disabled population—

death and recovery. The symbol represents the probability

of death in the presence of the other decrements and is defined

as follows:

 = 

where is the probability of continuance under all decrements; and is the force of mortality. The probability of

recovery is similarly defined.

For each cause of decrement in a multiple-decrement model, it

is possible to associate a single-decrement rate that depends

only on a particular cause of decrement. For example, 

represents the single-decrement (absolute) rate of death and is

defined as follows:

= 

where is the probability of not dying. In this representation, beneficiaries who decrement for causes other than death

are “taken out” of the total number exposed. Observation stops

at the point of non-death decrement resulting in total exposure

which is somewhat less than that used in formulating death

probabilities.

For example, the multiple-decrement probability is calculated for each combination of entitlement age and duration by

dividing the observed number of deaths by the exposure for

that cell. Assuming a uniform distribution for each decrement

over the age interval , the absolute rate of death 

can be calculated by dividing the observed number of deaths

by the exposure for that cell reduced by one-half of the number

of recoveries observed for that cell. The absolute rate of recovery is similarly defined.

This study uses an alternative method to calculate absolute

rates. First, derive the total decrement probability:

Then derive the absolute rates using the assumption of constant

force for each decrement over the age interval :

Absolute rates are presented on a “per thousand” basis.

J. Annuity Tables

In general, a life annuity is a series of payments made at regular intervals (such as months or years) during the lifetime of the

annuitant. Payments may be limited to a given number of

years, or payable for the whole of life, and are made at the

beginning (due) or end (immediate) of each period. Any standard actuarial text on life contingencies will explain the present

value calculation of an annuity.

The table below illustrates the present value of lifetime combined DI and OASI benefits (considering only the possibility

of death), as well as DI benefits to age 66 (NRA) for a male

worker entitled to disability benefits at age 50. To simplify calculations, we assume no cost-of-living adjustments to benefits.

K. Adjusted Decrement Rates

Shifts in the age, gender, and impairment composition of the

DI rolls occur over time. To compare disability rates of death

and recovery between different observation periods, we need to

eliminate the distortions caused by these shifts. For this reason,

gross rates are adjusted to provide a measure of the rate at

which disabled individuals are dying or recovering that is independent of demographic and programmatic shifts.

As explained in section D of this appendix, gross decrement

rates are calculated by dividing the observed number of deaths

or recoveries in an interval by the aggregate exposure for that

interval. Adjusted decrement rates for a group of beneficiaries

in an particular observation period are calculated by dividing

the total number of adjusted deaths or recoveries by the aggregate exposure for that group in the standard DI beneficiary

population. “Adjusted” decrements represent the number that

would occur in a group if the exposure had the same age-sexduration-specific profile as the exposure of the standard population, and are computed by multiplying the age-sex-durationspecific decrement rates of the particular observation period by

the age-sex-duration-specific exposures of the standard population. The resulting adjusted decrements are summed across

durations (or over select ages) and divided by the corresponding exposure of the standard population to get durationadjusted (or age-adjusted) rates.

The following tables compare the adjusted death and recovery

rates for various age and duration groupings, over the 20-year

period 1991-2010. Results are split into four different 5-year

observation periods. The standard DI beneficiary exposure

population used in the calculations corresponds to the 2006-10

observation period. Note that data is not available (“n/a”) for

several age groups in the 1991-95 and 1996-00 periods due to

data limitations and methods particular to those studies.

Tables K1-K4 show adjusted death rates by various entitlement age, attained age, and duration groupings. In general, DI

disabled worker death rates have steadily declined over all

observation periods. The overall death rate of 45.8 deaths per

thousand as measured in 1991-95 has fallen 20% to 36.7 in

2006-10. Most of the decline (17%) occurred in the last 10

years. Over the period measured, male mortality rates were

down 21% compared to 18% for females. The reasons for mortality improvement among disabled workers have been discussed in detail in this and the prior three actuarial studies

dedicated to the specific observation periods. Main factors

include a greater proportion of mental and musculoskeletal

impairments, advancement in medical treatments, and broader

use of vocational factors in disability determinations.

Tables K5-K8 show adjusted recovery rates by various entitlement age, attained age, and duration groupings. Chance of

recovery is not applicable beyond normal retirement age, at

which time disabled workers are converted to old-age benefits.

As detailed throughout the prior studies, changes in recovery

experience can be less intuitive than changes in mortality experience since rates are largely affected by exogenous variables.

The overall recovery rate spiked to 8.5 recoveries per thousand

in 1996-00 before settling back to 6.8 in 2001-05. This was followed by a 22% drop to 5.3 in 2006-10. The erratic pattern is,

in part, due to a spike in recoveries from eliminating DA&A

impairments in the 1996-00 period, followed by constraints in

special funding needed to complete CDRs in the 2006-10

period.

VI. TUTORIAL

In this section, we explain probabilities, continuance tables, and the select-and-ultimate (S&U) structure of the data,

where entitlement age denotes age last birthday at entitlement to disability benefits, duration is the number of completed years of disability entitlement, and attained age is the sum of entitlement age and duration.

Probability of Death (Refer to Table 7A)

A male disabled worker who became entitled to DI benefits at age 50—denoted as male [50]—has probability

.047733 of dying in the first year on the rolls. The probability of not dying in the first year is (1 - .047733) = .952267.

Similarly, we find the following probabilities in table 7A by duration:

Male [50] after 5 years entitled has probability .028373 of death in year 6 after attaining age 55

Male [50] after 10 years entitled has probability .034318 of death in year 11 after attaining age 60

Male [50] after 15 years entitled has probability .041976 of death in year 16 after attaining age 65

We refer to the values in the last column of S&U tables as ultimate because at high durations we assume the chance

of dying is not affected by an incremental increase in duration. In the ultimate period, beneficiaries of the same

attained age will have the same probability of death within the next year:

Male [30] after 30 years entitled has probability .034318 of death in year 31 after attaining age 60

Male [40] after 20 years entitled has probability .034318 of death in year 21 after attaining age 60

Male [50] after 10 years entitled has probability .034318 of death in year 11 after attaining age 60

Before duration 10 however, the probability of dying within the next year does depend on the entitlement age and

duration, so we find the probability of death in the select part of the S&U table:

Male [54] after 6 years entitled has probability .034824 of death in year 7 after attaining age 60

Male [56] after 4 years entitled has probability .032278 of death in year 5 after attaining age 60

Male [58] after 2 years entitled has probability .037491 of death in year 3 after attaining age 60

Benefit Continuance Table (Refer to Table 8A)

We can also calculate the probability that a disabled beneficiary will remain entitled for a certain number of years

using table 7A. However, this calculation becomes tedious after several iterations:

Probability male [50] remains entitled 1 year = (1-.047733) = .952267

Probability male [50] remains entitled 3 years = (1-.047733) x (1-.034242) x (1-.029994) = .892075

Probability male [50] entitled for 5 years will remain entitled another 10 years =

(1-.028373) x (1-.029795) x (1-.031248) x (1-.030506) x (1-.033644) x (1-.034318) x

(1-.036444) x (1-.038363) x (1-.041034) x (1-.042186) = .703177

The values, however, are easily calculated using table 8A. Note that the numbers in this table are not actual counts of

beneficiaries, but rather an assumed number living at the beginning of each duration corresponding to the probabilities derived from table 7A and an initial arbitrary value of 100,000 (called the radix) at entitlement age 16, duration 0.

Differences in the precision of the following probabilities as compared with those derived directly from table 7A are

due to rounding the number of lives to integer values in constructing table 8A:

Probability male [50] remains entitled 1 year = 72,355 / 75,982 = .952265

Probability male [50] remains entitled 3 years = 67,781 / 75,982 = .892067

Probability male [50] entitled for 5 years will remain entitled another 10 years = 44,929 / 63,894 = .703180

_________________________________________________________________

In this section, we explain expectation and the differences in the interpretation of the numbers for death, recovery, and

combined experience.

Expected Future Time on Combined OASDI Rolls (Refer to Table 9A—Death Experience Only)

In table 9A, we measure how long a beneficiary may remain on the combined OASDI rolls before dying. We do not

consider recovery. In this context, we expect a male [50] who just became entitled to DI to remain entitled for 18.86

years if he does not die. If he lives 10 years and is on the DI rolls at attained age 60 then we expect him to remain entitled for another 14.46 years. If he lives 30 years and is on the OASI rolls at attained age 80 then we expect him to

remain entitled for another 5.98 years (table 9C). Note that table 9A only shows how long we expect a beneficiary to

live and remain entitled. It does not reflect the chance of recovering.

Expected Future Time on DI Rolls (Refer to Table 16A—Recovery Experience Only)

In table 16A, we measure how long a beneficiary may remain on the DI rolls before recovering or switching to oldage benefits. We do not consider death. In this context, we expect a male [50] who just became entitled to DI to

remain entitled for 15.62 years if he does not recover. If he has not recovered after 10 years and is on the DI rolls at

attained age 60 then we expect him to remain entitled for another 5.98 years. Note that similar to table 9A, table 16A

only shows how long we expect a beneficiary to not recover and remain entitled. It does not reflect the chance of

dying. In order to measure the total amount of time we expect a beneficiary to remain on the rolls, we must consider

both death and recovery.

Expected Future Time on Combined OASDI Rolls (Refer to Table 23A—Combined Experience)

In table 23A, we measure how long a beneficiary may remain on the combined OASDI rolls considering both death

and recovery. In this context, we expect a male [50] to remain entitled for 18.33 years. If after 10 years he is still on

the DI rolls at attained age 60 then we expect him to remain entitled for another 14.40 years. After a DI beneficiary

converts to OASI benefits at NRA, we no longer track the occurrence of recovery, however, we continue to track the

occurrence of death.

Expected Future Time on DI Rolls (Refer to Table 24A—Combined Experience)

In table 24A, we measure how long a beneficiary may remain on the DI rolls. Observation stops once the beneficiary

dies, recovers, or switches to OASI benefits. In this context, we expect a male [50] to remain on the DI rolls for 12.03

years. Similarly, we expect a male [60] who has been on the DI rolls for two years and is attained age 62 to remain on

the DI rolls for another 3.70 years.

_________________________________________________________________

In this section, we explain absolute rates and address the issue of designing a single decrement model that is

restricted to a particular cause of decrement in a multiple-decrement environment. In such a model, one decrement

does not “compete” with other decrements in the sense that all other decrements are “removed” once they are

observed. We will clarify this concept in the examples that follow. In table 10, we isolate death as a particular cause of

decrement. In table 17, we isolate recovery as a particular cause of decrement.

Absolute Death Rate per Thousand Entitled (Refer to Table 10A)

The probabilities in table 7A are calculated by dividing the total number of deaths observed in an entitlement-ageand-duration “cell” by the total exposure for that cell. In the single-decrement model, we subtract the exposure from

all the beneficiaries who recover in that same cell—if they recover then they are no longer exposed to the decrement

of death. Note that by reducing the amount of exposure for that cell, the probability of death is calculated to be

slightly higher.

In actuarial mathematics, we avoid calling this re-calculated value a “probability” because some of the persons providing exposure exit before the end of a duration for a different decrement. So we express this quantity as a rate per

thousand per year. Dividing the number of deaths by the reduced exposure and multiplying by 1000 gives us an absolute death rate. In the first year of entitlement, a male [50] has an absolute rate of 47.798 deaths per 1000 beneficiaries as found in table 10A, which is slightly higher than 1000 times the probability shown in table 7A.
101

Absolute Recovery Rate per Thousand Entitled (Refer to Table 17A)

Similarly, the probabilities in table 14A are calculated by dividing the total number of recoveries by the total exposure for a particular cell. In the single-decrement model, we adjust for the beneficiaries who die in a particular cell.

Dividing the number of recoveries by the reduced exposure and multiplying by 1000 gives us an absolute recovery

rate. In the first year of entitlement, a male [50] has an absolute rate of 2.756 recoveries per 1000 beneficiaries as

found in table 17A. Again, this is slightly higher than 1000 times the probability shown in table 14A.

_________________________________________________________________

In the next 3 sections, we explain the grouping methods used to aggregate data by entitlement age, attained age, and

duration.

Aggregate Probability of Death and Expected Future Time, by Entitlement Age (Refer to Table 11)

In this aggregation, we calculate the probability of death by summing the number of deaths across all durations for

each entitlement age and divide by the total exposure for that age. For example, tabulations show that for males entl

age 50 there are 45,750 total deaths and 1,112,892.90 total life-years of exposure in the observation period 2006-10:

The aggregate probability of death within the next year is:

45,750 / 1,112,892.90 = .041109

This value is calculated for each entitlement age 16-65. The series is then graduated—for example, the above value is

adjusted to be .041114—and the results are shown in table 11.

The aggregate future time is a weighted-average of all the individual expected future times found in table 9A. Each

expected time is weighted by the total life-years of exposure for that cell. For example:

Multiply (expected time) x (exposure) and sum to get total exposure-weighted future time 16,918,854.85 and the

aggregate expected future time for male entitlement age 50 is:

16,918,854.85 / 1,112,892.90 = 15.20

This value is calculated for each entitlement age 16-65. The results are shown in table 11. Similar calculations are

performed for table 18 and table 25.

Aggregate Probability of Death and Expected Future Lifetime, by Attained Age (Refer to Table 12)

In this aggregation, we calculate the probability of death by summing the number of deaths across all durations for

each attained age and divide by the total exposure for that age. For example, tabulations show that for males attained

age 50 there are 21,170 total deaths and 724,837.86 total life-years of exposure in the observation period 2006-10:

The aggregate probability of death within the next year is:

21,170 / 724,837.86 = .029206

This value is calculated for each attained age 16-75. The series is then graduated—for example, the above value is

adjusted to be .029207—and the results are shown in table 12.

The aggregate future time is a weighted-average of all the individual expected future times found in table 9A. Each

expected time is weighted by the total life-years of exposure for that cell. For example:

Multiply (expected time) x (exposure) and sum to get total exposure-weighted future time 14,126,387.70 and the

aggregate expected future time for male attained age 50 is:

14,126,387.70 / 724,837.86 = 19.49

This value is calculated for each attained age 16-75. The results are shown in table 12. Similar calculations are performed for table 19 and table 26.

Aggregate Probability of Death and Expected Future Lifetime, by Duration (Refer to Table 13)

In this aggregation, we calculate the probability of death by summing the number of deaths for each duration and

divide by the total exposure for that duration. For example, tabulations show that for males in the first year of entitlement (duration 0) there are 129,932 total deaths and 2,324,476.32 total life-years of exposure in the observation

period 2006-10:

The aggregate probability of death within the next year is:

129,932 / 2,324,476.32 = .055897

This value is calculated for each duration 0-40. The series is then graduated—for example, the above value is

adjusted to be .055896—and the results are shown in table 13.

The aggregate future time is a weighted-average of all the individual expected future times found in table 9A. Each

expected time is weighted by the total life-years of exposure for that cell. For example:

Multiply (expected time) x (exposure) and sum to get total exposure-weighted future time 45,606,117.37 and the

aggregate expected future time for male duration 0 is:

45,606,117.37 / 2,324,476.32 = 19.62

This value is calculated for each duration 0-40. The results are shown in table 13. Similar calculations are performed

for table 20 and table 27.

Annuity Values (Refer to Tables 28-31)

Once entitled to Social Security DI benefits, the beneficiary receives monthly cash payments as long as he remains

entitled. To calculate the present value of future benefits (PVFB), we discount a stream of future cash payments using

an assumed interest rate to account for the time-value of money. In addition, we discount for survivorship to account

for the condition that the beneficiary must remain entitled or “survive” to the next payment.

The following illustration shows the value of a disability benefit payable to age 66 (NRA). The value found in table

30B for a male entitled at age 58 assuming 3% annual interest rate and continuance experience shown in table 22A is

calculated as shown below. We simplify the mathematics by using a hypothetical annual payment (instead of

monthly), and annual interest and continuance factors. For example, instead of a monthly DI benefit of $1500, we

assume the beneficiary receives an annual benefit of $18,000 at the end of each duration up until he attains age 66:

The interest factor represents the amount of money that, if invested at 3% annual interest, will grow to $1 by the end

of the stated duration. Discounting for interest is the first part of the PVFB calculation—the present value of the

annual payment made at the end of duration 0 (discounting for interest only) is:

PV = $18,000 x (.970874)

 = $17,475.73

The continuance (survivorship) factor is derived from table 22A and represents the probability that the beneficiary

makes it to the next payment by neither dying nor recovering. For example, the probability of making it to the first

payment is:

21,946 / 23,541 = .932246

The present value of the annual payment made at the end of duration 0 (discounting for interest and survivorship) is

called the actuarial present value, and is calculated as:

APV = $18,000 x (.970874 x .932246)

 = $18,000 x (.905093)

 = $16,291.67 

This dollar amount is shown in the last column of the above table. The PVFB is the sum of the APV over all durations

= $102,960.82. Shown in the second-to-last column is the series of APV factors = (interest factor) x (survivorship

factor). Summing these factors over all durations gives the annuity value shown in table 30B, which is easily used to

calculate PVFB directly:

PVFB = $18,000 x 5.720

 = $102,960

Administrative Law Judge. An official of the Social Security Administration’s Office of Disability Adjudication and

Review (ODAR) who is specially qualified to hold hearings

and make independent decisions regarding eligibility for

SSA programs on the basis of all evidence and testimony.

ALJs conduct impartial hearings and issue decisions to

claimants who have appealed previous determinations by

SSA.

Allowance (or denial). A determination by the Disability

Determination Services, ODAR, or federal district court that

a claimant meets (or does not meet) the medical definition of

disability under the Social Security Act.

Appeals Council. The organization within ODAR that

makes the final decision in the administrative review process. The council is the last line of appeal within SSA for

partially favorable or unfavorable decisions. A claimant’s

next recourse would be the federal court system.

Auxiliary benefits. Monthly benefits payable to a spouse or

child of a retired or disabled worker, or to a survivor of a

deceased worker.

Award. An administrative determination that an individual

is entitled to receive a specified type of OASDI benefit.

Awards can represent not only new entrants to the benefit

rolls but also for persons already on the rolls who become

entitled to a different type of benefit. Awards usually result

in the immediate payment of benefits, although payments

may be deferred or withheld depending on the individual’s

particular circumstances.

Baby boom. The period from the end of World War II

(1946) through 1965 marked by unusually high birth rates.

Beneficiary. A person who has been awarded benefits on

the basis of his or her own or another’s earnings record. The

benefits may be either in current-payment status or withheld.

Code of Federal Regulations. A record of the general and

permanent rules published in the Federal Register by executive departments and agencies of the Federal government.

The second volume (parts 400-499) of this three-volume

publication includes sections under Title 20, Chapter III,

which cover OASDI, SSI, and all other regulations issued by

the Social Security Administration.

Concurrent claim/benefit. A claim for both Title II (Social

Security) and Title XVI (Supplemental Security Income)

benefits. Since SSI provides “assistance of last resort”—

taking into account all income and resources that an individual has—concurrent beneficiaries must include Title II cash

benefits as part of income when determining the amount of

Title XVI benefits to be received.

Continuing Disability Review. An evaluation to determine if a disability beneficiary is still eligible for cash benefits. Payment of benefits will end if medical or other

evidence shows the beneficiary is no longer disabled under

the standards set in the Social Security Act. The frequency

of reviews varies by the severity of impairment or can be

“triggered” by work activity.

Current-payment status. Status of a beneficiary to whom

a benefit is being paid for a given month.

Diagnostic group. Classification of impairments, by body

system, which identifies the medical condition(s) underlying

a disability. Before 1985, the coding of primary and secondary diagnoses for Social Security claimants was in accordance with the International Classification of Diseases: 9th

Revision using 4-digit ICD-9 codes. In 1985, SSA implemented a revised impairment coding system using 3 digits

followed by a zero. Although not identical, the new codes

closely parallel the major ICD-9 categories.

Disability conversion. Automatic conversion of a disabled

worker beneficiary to retired-worker status upon attainment

of normal retirement age.

Disability Determination Services. The state agency

responsible for developing medical evidence and rendering

the initial determination and reconsideration on whether a

claimant is disabled or a beneficiary continues to be disabled

within the meaning of the Social Security Act.

Disability incidence rate. The proportion of workers in a

given year, insured for but not receiving disability benefits,

which apply for and are awarded disability benefits. Gross

incidence rates are calculated as the ratio of the total number

of awards for a given year to the total exposure for that year.

Age-adjusted incidence rates are calculated as the ratio of

the total number of adjusted awards for a given year to the

total exposure for the standardizing year. For example, mul-
106

tiplying single-year-of-age incidence rates in 2010 by the

exposure for those same ages in, say, 2000 would give

adjusted awards. The age-adjusted incidence rate for 2010 is

then calculated as the total number of adjusted awards

divided by the total exposure for 2000.

Gross rates are not directly comparable over time because of

the year-to-year differences in the age and sex composition

of the underlying insured population. We adjust gross rates

to factor out these effects allowing for a “cleaner” comparison of rates from year to year.

Disability termination rate. The proportion of disabledworker beneficiaries in a given year whose disability benefits terminate because of the individual’s death or recovery.

Drug Addiction and Alcoholism. If shown to be material

to the determination of disability, drug addiction or alcoholism will prevent entitlement to benefits or cause removal

from the rolls.

Exposure. In general, exposure is a measure of the amount

of time that a cohort of individuals are exposed to the possibility of an event, such as disability, death, or recovery. The

quantity of measurement is called “life-years”. There are different methods of calculating life-years of exposure. With

regard to incidence of disability, we measure the amount of

time that a cohort of workers (who are not already disabled)

are exposed to the possibility of becoming disabled over the

course of a year. Alternatively, you can think of this quantity

as the average number of disability-insured workers for the

year who are not already receiving benefits.

With regard to the select-and-ultimate tables for death or

recovery probabilities presented in this study, exposure

depends on how long beneficiaries are “scheduled” to be on

the disability rolls during a specific period of time (called

the “observation period”). There are various ways to calculate this quantity as well and the reader is referred to the

appendix for details.

Federal court review. When an individual disagrees with

SSA’s final decision in the administrative review process,

they may request judicial review by filing a civil action in a

federal district court.

Hearing. The level following reconsideration in the administrative review process. The hearing is a de novo procedure

at which the claimant and/or representative may appear in

person, submit new evidence, give testimony, and present

witnesses.

Initial determination. The first decision made in determining entitlement to benefits. The field office makes the decision on nonmedical factors such as insured status or

substantial gainful activity. If nonmedical factors are met,

DDS adjudicators make the decision on the medical factors.

Listing of Impairments. Describes, for each major body

system, impairments which are considered severe enough to

prevent a person from doing any gainful activity. Most of the

listed impairments are permanent or expected to result in

death, or a specific statement of duration is made. For all

others, the evidence must show that the impairment is

expected to last at least 12 months.

Maximum family benefit . The maximum monthly amount

that can be paid on a worker’s earnings record. Whenever

the total of the individual monthly benefits payable to all

beneficiaries entitled on one earnings record exceeds the

maximum, each auxiliary benefit is proportionately reduced

to bring the total within the maximum.

Normal retirement age. The age at which a person may

first become entitled to unreduced retirement benefits (see

chart on page 1).

Pre-effectuation review. A comprehensive on-going program under which a prescribed percentage of determinations

involving the issue of disability are evaluated prior to their

effectuation, even though there is no request for review.

Recession. A period of adverse economic conditions; in

particular, two or more successive calendar quarters of negative growth in GDP.

Reconsideration. An independent reexamination of all evidence on record related to a case. It is based on the evidence

submitted for the initial determination and any further evidence or information that the claimant submits. Adjudicators

making a reconsideration determination are different from

those who made the initial determination.

Recovery. The termination of disability benefits because of

medical improvement or a successful reentry to the workforce.

Replacement rate. The ratio of the total amount of (annualized) cash benefits received during the first year of entitlement to the total earnings of the beneficiary in the

immediately preceding year. This ratio measures the fraction

of prior earnings that are replaced by current benefits.

Residual Functional Capacity. A measurement of the

amount of activity an individual can perform in spite of

physical or mental limitations. Disability adjudicators assess

the extent that the impairment(s) prevent the claimant from

performing particular work activities, and use RFC to determine the types of work that can be performed despite

impairments.

Retroactive benefits. Benefits that are paid for months that

have already passed. For disability cases, the retroactive

period can include up to 12 months prior to application for

benefits; and can also include any number of months

between application and award.

Social Security Act. Provisions of the law governing most

operations of the Social Security program. Title II of the Act

authorized the Old-Age, Survivors, and Disability Insurance

program. Title XVI of the Act authorized the Supplemental

Security Income (SSI) program.

107

Statutory blindness. Central visual acuity of 20/200 or less

in the better eye with the use of a correcting lens or tunnel

vision of 20 degrees or less.

Supplemental Security Income. A federal program for

low-income aged, blind, and disabled individuals who meet

income and resource requirements. SSI is funded by general

tax revenues, not Social Security taxes.

Vocational factors. When it is determined that a claimant

cannot perform past relevant work based on residual functional capacity alone, adjudicators further consider vocational factors of age, education, and work experience to

determine the claimant’s ability to adjust to other work that

exists in significant numbers in the economy.

Workers’ Compensation offset. A reduction in the

monthly benefits for a disabled-worker family when the

monthly DI cash benefit amount plus the State or Federal

workers’ compensation benefit amount or other Federal,

State, or local disability benefits (excluding VA or needsbased benefits or benefits based on Federal, State, or local

covered employment) exceeds 80 percent of the worker’s

average current earnings before the onset of disability. The

offset is imposed for any month in which individuals are

entitled to both DI benefits and other applicable benefits.
