FOREWORD

The most recent work dedicated to presenting actuarial experience of the Social Security Disability Insurance (DI) 

program is Actuarial Study #118, Social Security Disabiity Insurance Program Worker Experience (June 2005). The 

study examined historical data with regard to disability incidence and benefit termination through calendar year 2004. 

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 1996-2000. The overall content of Actuarial Study #122, 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 2009, and a comprehensive analysis of termination activity is presented for the 

5-year period 2001-05. Details of the underlying methodology for table construction are outlined in the appendix.

This study does not present projections of actuarial cost estimates for the DI program. For this information, the reader 

is referred to Actuarial Study #121, Short-Range Actuarial Projections of the Old-Age, Survivors, and Disability 

Insurance Program, which was developed to provide a detailed description of the methodology and assumptions used 

in projecting the costs associated with the entire OASDI program.

The study is also available on the Social Security Administration’s website at www.socialsecurity.gov/OACT/

pubs.html. Additional copies of the study are available upon request. Please refer to the inside cover for details. 

Finally, readers are welcome to provide comments or suggestions regarding any of the material contained within.

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 recency-of-work 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 2010, a worker receives one credit (up to a maximum of four) for each 

$1,120 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 is immaterial whether such work 

exists in the claimant’s immediate area, or whether a specific 

job vacancy exists, or whether the claimant would be hired if 

he or she applied for work.

When an individual applies for benefits under title II of the 

Act, a five-step sequential evaluation process is used to decide 

whether disability exists. Claim processing stops as soon as a 

favorable or unfavorable determination can be reached.

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

claimant is working and the work is SGA, then he or she is not 

disabled for Social Security purposes. Otherwise, the adjudicator continues with claim processing.

Step 2—Determine if impairment is “severe”. If the impairment or combination of impairments do not significantly limit 

the claimant’s physical or mental ability to do basic work activities, then he or she is found to be not disabled. Otherwise, the 

adjudicator continues with claim processing.

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

or medically equals a set of criteria in the Listing of Impairments. 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, then claimant is disabled. Otherwise, the 

adjudicator continues with claim processing.

Step 4—Determine if the claimant has the residual functional 

capacity (RFC) to do his or her past relevant work. An assessment is made of what the claimant is still able to do despite any 

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

cannot be accomplished, then the adjudicator continues with 

claim processing.

Step 5—Determine if the impairment prevents claimant from 

engaging in any other work that exists in significant numbers 

in the national economy. 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, then claimant 

is disabled. Otherwise, he or she is found to be not disabled for 

Social Security purposes.

The same definition of disability is applied to each of the following types of 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).

Special provisions exist 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 

Applications for worker disability benefits are taken by SSA 

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).

Once the technical aspects of the determination process are satisfied, 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 will 

consider things such as the nature of the claimant’s work, how 

well the work is performed, whether work is done under special conditions or uses special equipment, the amount of time 

spent at work, and, of course, 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, duties, 

and responsibilities.

Certain earnings criteria have been established as reasonable 

indications of whether an individual is engaging in SGA. The 

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, sufficient evidence is required of the 

claimant’s medical condition(s) 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 the determination of disability among workers age 50 or older.

C. Residual Functional Capacity (RFC)

Impairment(s) and any related symptoms, such as pain, may 

limit the ability to work. Residual functional capacity measures 

the most an individual can do despite 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 2010, a blind individual earning over $1,640 per month (net of impairment-related work expenses) is ordinarily considered to be engaging in SGA. 

The comparable amount for non-blind individuals is $1,000 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 is responsible for developing medical evidence and 

rendering the initial determination of whether the claimant is 

disabled or blind under the law. If dissatisfied with the initial 

DDS decision, the claimant has the right to 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 has the opportunity to submit new 

material evidence supporting the claim during any step of the 

review process. The information may be presented by the 

claimant or a representative, such as an attorney. 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 (un)employment in the U.S. economy;

• Relative size (attractiveness) of DI benefits versus loss of 

income;

• Changes in 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 claims for DI disability benefits across the various stages of review, for calendar 

years 1998-2009. The data are tabulated by year of filing, with 

an additional categorization by program involvement—showing claims for DI benefits only or concurrent entitlement to DI 

and SSI benefits. As mentioned earlier, both programs use the 

same definition of disability for adults. However, eligibility for 

SSI benefits is further dependent upon the claimant’s countable 

assets and income, which may include DI benefits.

5 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).
5

The number of claims forwarded to the DDS for DI disabled 

worker benefits grew to 1.53 million in 2004 from 1.04 million 

in 1998—nearly a 50 percent increase, with roughly a 10 percent increase occurring in each of 2001 and 2002. General reasons for the increase are the aging of the baby-boom, and 

higher levels of unemployment resulting from the economic 

contraction which began in the second quarter of 2001. In addition, the late 1990s exhibited marked increases in the number 

of disability insured workers, increasing the pool of those that 

may become eligible for benefits.

The number of disability claims remained steady throughout 

2005-08 at roughly 1.4 million per year. Although the babyboom continues to progress through the peak ages of disability, 

the level pattern likely reflects the stable demographic and economic conditions of the period—low unemployment, stable 

labor force participation (ages 16-64), and strong wage growth. 

In addition, there were no major legislative initiatives which 

might provide incentives to seek benefits. More recently, the 

number of claims spiked almost 20 percent to 1.8 million in 

2009, triggered by the severe economic recession that began in 

2008.

Initial Determinations

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

39.7 percent in 2001 from 33.7 percent in 1997. The growth 

during this period was likely due to a confluence of factors. 

The leading edge of the baby-boom began entering their late 

40s and early 50s; these are prime ages for musculoskeletal, 

circulatory, and neoplastic impairments—all high-allowance 

disorders. Another possible factor was an ad hoc increase in 

the dollar amount associated with defining SGA. The monthly 

level for non-blind workers was increased to $700 in 1999. 

This amount had not been changed since 1990, when it was set 

at $500. The higher level may have increased the potential of 

meeting the definition of disability for some claimants.

It is worth noting that 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.

Also note that for years with pending workloads, it is likely 

that the allowance rates will ultimately be lower than those 

shown in table 1. This is due to the fact that, on average, the 

processing time involved in an unfavorable decision is longer 

than that in making a favorable decision.

Reconsideration

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 seldom overturned at reconsideration.

Appeals Beyond Reconsideration

The subjectiveness in assessing disability leaves considerable 

room for differences in the interpretation of evidence. As a 

result, overturned decisions at ODAR and beyond remain relatively high. 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, there are several items that should be mentioned to assist the reader in interpreting 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.

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

to the initial decision.

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;

• 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.

As the DI program grows and disability claims become more 

complex to adjudicate, SSA is challenged to improve the accuracy, consistency, and fairness of decisions. To this end, other 

developments in the disability area deserve mention. The electronic disability (eDIB) process has substantially streamlined 

the collection and storage of claim data. Beginning in August 

2002, claimants have been able to apply for disability benefits 

online; as of January 2006, all state DDSs had begun using 

electronic disability folders.

Electronic filing facilitates initiatives such as quick disability 

determination (QDD). Under the QDD process, a predictive 

model identifies 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 within a 20-day 

time limit.

The compassionate allowance (CAL) initiative is designed to 

quickly identify diseases and conditions that are highly likely 

to qualify under the Listing of Impairments based on minimal 

medical information. For the rollout of the initiative, 50 conditions were chosen which meet the CAL guidelines. The list has 

since been expanded to include roughly 90 conditions such as 

early-onset Alzheimer’s disease, Lou Gehrig’s disease, and 

various cancers.

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 effectuating an initially favorable determination.

7 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.

Other events shaping the experience of disability incidence in 

more recent years include: the elimination of obesity from the 

listings in 1999 and the issuance of a new musculoskeletal listing in 2002; a correction to the disability rolls made by awarding benefits to disabled persons who were found to have an 

inaccurate record of insured status; the legislated increase in 

NRA beginning with those attaining age 65 in 2003; and the 

severe economic recession which began in the first quarter of 

2008.

B. Diagnostic Group Experience

Table 2 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 is now the largest single category of impairment. Over the 5-year period 2005-09, 29.3 percent of all 

awards were attributable to this category—a trend that is 

largely explained by demographics. As the baby-boom generation ages, arthritic, back, and bone disorders become more 

prevalent.

The 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 23.0 percent of all awards 

over 2005-09. A slight jump in mental disorders occurred over 

2003-05 due, in part, to the processing of the special disability 

workload (SDW). In 2001, SSA began reviewing a group of 

several hundred thousand SSI recipients who potentially 

became disability insured because of earnings while receiving 

SSI, making them eligible for DI benefits. Many of the resulting awards from this misplaced cohort were for individuals 

diagnosed with a mental disorder.
9

Among males, circulatory disorders have always been a leading cause of disability, accounting for roughly 13-16 percent of 

total awards over the last 10 years. Neoplasms account for 

roughly 9-11 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.

Awards based on neoplastic and metabolic impairments rank 

higher among females than males, whereas awards based on 

circulatory impairments rank lower. 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.

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 1986-2009. 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. Note, however, that the year of award may 

actually be different from the year of disability onset or entitlement. This is due to factors such as the waiting period, the 

nature of the determination process, and claims processing 

times in general. Consequently, the incidence rates shown are 

not necessarily representative of true morbidity rates for the 

stated calendar years.

The incidence of disability increases considerably as individuals age. The chance of suffering an impairment increases naturally with advancing age, but also education and job skills are 

factored into the determination decision. Note that the rates 

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

the true incidence of impairment in the insured population 

since, beginning at age 62, a disabled worker may elect to 

forgo disability benefits, opting instead to receive reduced oldage benefits. A number of factors influence this decision, 

including: potentially higher maximum family benefits under 

old-age as compared to disability; the potential for disability 

benefit reduction because of Federal or State workers’ compensation offset8

; and the potentially arduous application process and possibility of benefit denial.

Age-specific disability incidence among female workers is typically lower than males. However in 1997, female incidence 

began to exceed that for males at ages 35-54. Although both 

genders experienced a general decline in incidence in this age 

range over the following 5 years, 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. It is also interesting to note that the decline in incidence rates among females did not come from a decline in the 

number of benefits awarded, but from an increase in the exposure. 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 2001-04 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 be an incentive to seek disability benefits for older workers facing higher actuarial reductions for early retirement.

The period 2005-07 saw a small downward trend in awards, 

whereas 2008-09 saw a significant jump likely due to the 

severe recession that began in the first quarter of 2008.

Table 5 presents historical 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 1986-2009. 

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. Through 2009, 

the rolls increased an additional 60 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

The three main reasons for termination of DI disabled worker 

benefits are the following:

• Conversion. 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.9 The last month of 

disability entitlement would be the prior month. 

Conversions accounted for 54 percent of total disabled 

worker terminations in 2009.

• Death. The last month of disability entitlement would be 

the month prior to the month of death. Beneficiary death 

accounted for 36 percent of total disabled worker 

terminations in 2009.

• 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. 10 Recoveries accounted for 7 percent 

of total disabled worker terminations in 2009.

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. Such receipt 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.

An important caveat bears mention in 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 example, changes in the way medical impairments are adjudicated, the elimination of DA&A from the listings, and an increase in 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 

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 

9 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.

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

rehabilitation program, or has entered an extended period of eligibility.

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 2010, a service month is counted towards the TWP if earnings for that 

month exceed $720. A self-employed worker is charged with a service month 

if work activity exceeds 80 hours.
12

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

C. Recent Experience

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 disability reviews, the agency reduced the resources 

it committed to reviews. Beginning in 1994, the number of initial claims began to level-off and the agency wished to increase 

its review activity. 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 eliminate DI review backlogs by the 

end of 2000, and SSI backlogs by the end of 2002. However, 

the agency has not received full funding in recent years and has 

not been able to process all CDRs coming due.

Table 5 shows a historical series of the number of terminations 

and gross termination rates (defined as the ratio of the number 

of terminations to the average number of beneficiaries during 

the year) for disabled workers, by reason for termination. Most 

terminations occur as a result of conversion to retirement benefits or death. With the exception of a sharp decrease in conversions in 2003,15 the year-to-year changes in both categories are 

relatively small. In contrast, 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 mostly of beneficiaries who switch to old-age benefits prior to NRA.16

Figure 3 shows the distribution of DI disabled worker terminations by reason. Figure 4 shows the distribution of DI disabled 

worker terminations divided by the average number of disabled 

worker beneficiaries by reason. Until recently, these ratios 

have been declining mostly because of two somewhat-correlated trends that have developed over the years, namely, the 

reduction in the average age of beneficiaries and the increased 

share of mental disability.

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 

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 2009, the average male disabled worker in current-payment status was 52.8 years old, and 

the proportion of beneficiaries aged 35-49 declined to 24 percent, while the proportion of those aged 50-65 grew to 69 percent. Again, similar trends were experienced among females.

by Reason, Calendar Years 1986-2009

(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 spike in conversions in 2009.

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 (2001-05)

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

female DI disabled workers, by select age at entitlement to disability benefits; and duration—measured in years since selection. Data reflect the actual experience of the DI rolls from 

January 1, 2001 through December 31, 2005. The methods 

used in table construction and graduation are detailed in the 

appendix.

Mortality among disabled workers generally increases with 

select age, albeit this trend can be heavily influenced by the 

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

select 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 select 

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 2009, 

the top disorders for male awards under age 35 are mental 

(57%), musculoskeletal (10%), and nervous (9%). Following 

the predominant mental and musculoskeletal categories (combined 55%), ages 35-49 show a mix of circulatory (9%), nervous (8%), and neoplastic (7%) impairments. Ages 50 or older 

show the highest concentration of musculoskeletal (34%),

along with considerable increases in circulatory (17%) and 

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

the prevalence of mental impairments (10%) 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 2009, disabled females under age 35 show the highest concentration of mental (53%), musculoskeletal (14%), and 

nervous (11%) disorders. Ages 35-49 continue to show high 

incidence of mental and nervous impairments, along with large 

increases in musculoskeletal (30%) and neoplastic (9%) disorders. Ages 50 or older show the highest prevalence of musculoskeletal (40%), mental (14%), and neoplastic (12%) awards.

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

(2001-05) is lower than in the previous 5-year period for about 

three-quarters of sex-age categories.17 Among males, mortality 

in the more recent period is generally 5 to 20 percent lower 

than mortality in the earlier period, with dramatic reductions of 

35-40 percent at some younger select ages. Mortality among 

females is generally 5 to 15 percent lower than in the earlier 

period, but is sometimes as much as 25-30 percent lower. The 

improvements are likely due to both medical progress (for 

example, in the treatment of HIV) and the changing impairment mix. For example, there is a greater proportion of mental 

and musculoskeletal disorders in the later period (51 percent 

versus 45 percent) and disability where drug addiction and 

alcoholism are material to impairment are not grounds for entitlement in the later period.

Tables 8A-8C show the number of survivors remaining over 

time from cohorts becoming entitled at various ages. These 

tables are based on the probabilities of death shown in tables 

7A-7C. Survival tables make it easy to calculate the probabilities of surviving a given number of years. See the appendix for 

details on table construction and usage.

Tables 9A-9C show the expected future lifetime of disabled 

workers, which reflects the survivorship experience shown in 

tables 8A-8C. Similar to the general population, disabled 

females have a longer future lifetime than males. Life expectancy is often greater in the second year of entitlement than in 

the first year of entitlement, because of the high mortality during the first year on the rolls.

Tables 10A-10A 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 provides further details.

Tables 11 and 12 show the aggregate probability of death and 

expected future lifetime, by select and attained age. Probabilities are based on aggregate counts of exposure and deaths 

across all durations. They represent the average probability of 

death in the next year for beneficiaries originally entitled at a 

particular select age (table 11), or who have attained a particular age (table 12). Similarly, expected future lifetime represents 

the average life expectancy of beneficiaries who share a particular select or attained age. Values are exposure-weighted averages of the select-and-ultimate future lifetimes shown in tables 

9A-9C and may be used as a generally indication of the overall 

average lifetime of a particular entitlement cohort or a group of 

beneficiaries from various entitlement cohorts who have 

attained a particular age.

Table 13 shows the aggregate probability of death and 

expected future lifetime, by duration. Probabilities are based 

on aggregate counts of exposure and deaths across all select 

ages, and represent the average probability of death within the 

next year. Aggregate future lifetime represents the average life 

expectancy of beneficiaries who have been entitled for the 

stated number of years.

E. Actuarial Analysis—Recovery (2001-05)

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

female disabled workers, by select age and duration. In general, annual probabilities of recovery decline with advancing 

select age. For any particular select age, the probability of 

recovery exhibits a bimodal distribution that tends to peak during the second year of entitlement and then peaks again 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 the period 1999-2002:

• Roughly 5-10 percent of all reviews fall in the MIE 

category and roughly 10 percent of these reviews result in 

an initial cessation of benefits—which can still be 

appealed. This could help explain the first peak in 

recoveries.

17 Findings are based on comparisons with disability mortality tabulated for the 

period 1996-2000 in Actuarial Study No. 118 Social Security Disability Insurance 

Program Worker Experience (Zayatz, June 2005).
16

• Roughly 65-70 percent of all reviews fall in the MIP 

category and roughly 8 percent of these reviews result in 

an initial cessation of benefits. This could help explain the 

second peak in recoveries.

• The remaining 25-30 percent of all reviews fall in the 

MINE category and roughly 4 percent of these reviews 

result in an initial cessation of benefits.

The probability of recovery for females is lower than that for 

males for almost two-thirds of attained ages. This is especially 

true for attained ages less than 50 and may be due to differences in the mix of impairments among men and women. For 

example, data show that during the observation period 2001-

05, 42 percent of new awards to females under age 50 were for 

mental disorders, compared to 37 percent for males. Although 

somewhat speculative, the nature of these types of impairments 

seems to contribute to slightly lower recovery rates among 

younger females and consequently slighty longer expected 

times on the DI rolls.

Probabilities of recovery during the 2001-05 period are generally lower than in the 1996-2000 period, and often much 

lower.18 For most ages, the probability of recovery dropped by 

10 to 50 percent. It is likely that the higher rates in the earlier 

period were the result of several transitory factors, so much of 

the decline is a return to more “normal” rates of recovery. High 

probabilities over 1996-2000 were due, in part, to eliminating 

DA&A from the listings. The large number of terminations that 

occurred among cases where drug addiction and alcoholism 

were material to impairment were classified as “recoveries”. 

Also, much of the CDR backlog was worked off with the special funding provided by Public Law 104-121 in 1996.

Tables 15A-15B show the number of persons not yet recovered 

at different attained ages, for given select ages. They reflect the 

probabilities of recovery shown in tables 14A-14B. In this 

case, “survival” refers to beneficiaries who remain on the DI 

rolls by not recovering.

Tables 16A-16B show the expected number of future years of 

not recovering—up to normal retirement age—for those who 

have not yet recovered. The values are based on the survivorship experience shown in tables 15A-15B.

Tables 17A-17B show the absolute rate of recovery per thousand entitled disabled workers, which are derived from the 

probabilities of recovery shown in tables 14A-14B. The appendix provides details on the derivation of these rates.

Tables 18 and 19 show the aggregate probability of recovery 

and the expected time on the DI rolls, by select and attained

age, respectively. The values are based on aggregate counts of 

exposure and recoveries across all durations and represent the 

average probability of recovery in the next year for beneficiaries entitled at a particular select age (table 18), or who have 

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

the DI rolls represents the average number of future years of 

entitlement—up to NRA—for those still on the rolls. These 

values are exposure-weighted averages of the values shown in 

tables 16A-16B.

Table 20 shows the aggregate probability of recovery and 

expected time on the DI rolls, by duration. The probabilities 

are based on aggregate counts of exposure and recoveries 

across all select ages, and represent the average probability of 

recovery within the next year. The expected time on the DI 

rolls represents the average number of future years of not 

recovering for those who have not yet recovered.

F. Actuarial Analysis—Death or Recovery (2001-05)

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

male and female disabled workers, by select 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 the number of persons remaining on the 

rolls at different attained ages, for given select ages. Beneficiaries continue to be followed until death, even after their disability benefits are converted to retirement benefits.

Tables 23A-23B show the expected number of future years on 

the combined DI and OASI rolls, by select age and duration. 

Values are based on survivorship experience shown in tables -

22C.

Tables 24A-24B show the expected number of future years on 

the DI rolls, by select age and duration. Values are based on 

survivorship experience shown in tables 22A-22B and do not 

reflect entitlement beyond conversion to old-age benefits.

Tables 25 and 26 show the aggregate probability of death or 

recovery and the expected time on the beneficiary rolls, by 

select and attained age, respectively. The values represent the 

average probability of terminating due to death or recovery in 

the next year for beneficiaries entitled at a particular select age 

(table 25), or who have attained a particular age (table 26). 

Expected time on the OASDI rolls represents the average number of future years of combined entitlement for those originally 

entitled to disability benefits, and are exposure-weighted averages of expected time on the rolls shown in tables 23A-23B. 

Aggregate expected time on the DI rolls represents the average

Actuarial Study No. 118 Social Security Disability Insurance Program Worker 

Experience (Zayatz, June 2005).
17

number of future 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 time on the beneficiary rolls, by duration. 

They represent the average probability of leaving the rolls by 

death or recovery in the next year. 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 select age at entitlement. 

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 (annuity-immediate) 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 29A-29D recognize only the risk of death and payments may continue 

beyond NRA, thus they use survivorship 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, thus they use survivorship experience shown in tables 22A22B. The appendix gives details of the table construction and 

its usage.

Death Experience

by Select Age and Duration

(2001-05)
.
27

Notes:

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

age and duration. Results do not include auxiliary beneficiaries payable under the DI program.

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 select age [x] who have attained age [x]+t.

3. Select-and-ultimate table is read across the row for 0-10 years since selection, and down the last (ultimate) column for 10 or more years since selection. 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. Select age denotes age last birthday at entitlement to disability benefits. Duration measured in years since selection. Attained age calculated as sum of select 

age and duration. Results do not include auxiliary beneficiaries payable under the DI program.

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 select age [x] who have attained age [x]+t.

3. Select-and-ultimate table is read across the row for 0-10 years since selection, and down the last (ultimate) column for 10 or more years since selection. 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. Select age denotes age last birthday at entitlement to disability benefits. Duration measured in years since selection. Attained age calculated as sum of select 

age and duration. Results do not include auxiliary beneficiaries payable under the DI program.

2. The value at duration t represents the average number of years of life remaining for those originally entitled to disability benefits at select age [x] who 

have attained age [x]+t. Values are based on survivorship experience from tables 8A and 8C.

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

table 9C for attained ages beyond age 75.

Notes:

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

age and duration. Results do not include auxiliary beneficiaries payable under the DI program.

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 select 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 since selection, and down the last (ultimate) column for 10 or more years since selection. See 

table 10C for attained ages beyond age 75.

Notes:

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

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

originally entitled to disability benefits 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 lifetime at select age [x] represents the aggregate life expectancy in years for those originally entitled 

to disability benefits at that particular age. Values are exposure-weighted averages of expected future lifetime 

across all durations from tables 9A, 9B and 9C.

Notes:

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

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

originally entitled to disability benefits 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 lifetime at attained age x represents the aggregate life expectancy in years for those originally entitled 

to disability benefits who have attained that particular age. Values are exposure-weighted averages of expected 

future lifetime across all durations from tables 9A and 9B. See table 9C for attained ages beyond age 75.

Notes:

1. Duration measured in years since selection.

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 select ages. 

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

established in table 7C.

3. Future lifetime at duration t represents the aggregate life expectancy in years for those originally entitled to 

disability benefits who have not died after t years. Values are exposure-weighted averages of expected future 

lifetime across all ages from tables 9A, 9B and 9C.

Notes:

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

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

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 select age [x] who have attained age [x]+t.

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

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

Notes:

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

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

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 select age [x] who have attained age [x]+t.

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

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

Notes:

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

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

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

t > 0 represents the number of lives from the original who have not recovered and remain on the DI 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 since selection, and down the last (ultimate) column for 10 or more years since selection.

Notes:

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

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

2. The value at duration t represents the expected number of future years of DI entitlement for those originally entitled to benefits at select age [x] who 

have not recovered as of attained age [x]+t. Values are based on survivorship experience from table 16A, which reflects termination due to recovery only.

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

Notes:

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

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

2. The value at duration t represents the expected number of future years of DI entitlement for those originally entitled to benefits at select age [x] who 

have not recovered as of attained age [x]+t. Values are based on survivorship experience from table 15B, which reflects termination due to recovery only.

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

Notes:

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

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

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 select 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 since selection, and down the last (ultimate) column for 10 or more years since selection.

Notes:

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

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

those originally entitled to disability benefits 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. Time on DI rolls at select age [x] represents the average number of future years of DI entitlement for those 

originally entitled to benefits at that particular age who have not recovered. Values are exposure-weighted 

averages of expected time on the DI rolls across all durations from tables 16A and 16B, which reflect 

termination due to recovery only. Entitlement is not considered after conversion to old-age benefits.

Notes:

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

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

those originally entitled to disability benefits who have attained that particular age. Values are based on 

aggregate counts of exposure and recoveries across all durations, and have been graduated using WhittakerHenderson method.

3. Time on DI rolls at attained age x represents the average number of future years of DI entitlement for those 

who have not recovered, and have attained that particular age. Values are exposure-weighted averages of 

expected time on the DI rolls across all durations from tables 16A and 16B, which reflect termination due to 

recovery only. Entitlement is not considered after conversion to old-age benefits.

Notes:

1. Duration measured in years since selection.

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

entitlement to benefits. Values are based on aggregate counts of exposure and recoveries across all select ages. 

Results have been graduated using Whittaker-Henderson method.

3. Time on DI rolls at duration t represents the average number of future years of DI entitlement for those who 

have not recovered after t years. Values are exposure-weighted averages of expected time on the DI rolls across 

all ages from tables 16A and 16B, which reflect termination due to recovery only. Entitlement is not 

considered after conversion to old-age benefits.

Notes:

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

age and duration. Results do not include auxiliary beneficiaries payable under the DI program.

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 select age [x] who have attained age [x]+t. Values are derived from death probabilities shown in table 7A and recovery probabilities shown in table 

14A.

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

table 7C for death probabilities beyond attained age 75.

Notes:

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

age and duration. Results do not include auxiliary beneficiaries payable under the DI program.

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 select age [x] who have attained age [x]+t. Values are derived from death probabilities shown in table 7B and recovery probabilities shown in table 

14B.

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

table 7C for death probabilities beyond attained age 75.

Notes:

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

age and duration. Results do not include auxiliary beneficiaries payable under the DI program.

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

t > 0 represents the number of lives remaining from the original who have 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 since selection, and down the last (ultimate) column for 10 or more years since selection. 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.

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

of tables 22A and 22B.

Notes:

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

age and duration. Results do not include auxiliary beneficiaries payable under the DI program.

2. The value at duration t represents the expected number of future years of combined DI and OASI entitlement for those originally entitled to disability

benefits at select age [x] who have not died or recovered as of attained age [x]+t. Values are based on survivorship experience from tables 22A and 22C, and 

reflect automatic conversion to old-age benefits upon attaining normal retirement age.

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

table 9C for expected future lifetimes beyond attained age 75.

Notes:

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

age and duration. Results do not include auxiliary beneficiaries payable under the DI program.

2. The value at duration t represents the expected number of future years of DI entitlement for those originally entitled to benefits at select age [x] who 

have not died or recovered as of attained age [x]+t. Values are based on survivorship experience from table 22A. Entitlement is not considered after conversion 

to old-age benefits.

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

Notes:

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

2. Probability of death or recovery at select age [x] represents the average probability of total decrement within one year for those originally 

entitled to disability benefits 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. Time on OASDI rolls at select age [x] represents the average number of future years of combined DI and OASI entitlement for those originally 

entitled to disability benefits at that particular age. Values are exposure-weighted averages of expected time on the combined rolls across all 

durations from tables 23A, 23B and 9C, and reflect automatic conversion to old-age benefits upon attaining normal retirement age.

4. Time on DI rolls at select age [x] represents the average number of future years of DI entitlement for those originally entitled to benefits at that 

particular age. Values are exposure-weighted averages of expected time on the DI rolls across all durations from tables 24A and 24B. Entitlement 

is not considered after conversion to old-age benefits.

Notes:

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

2. Probability of death or recovery at attained age x represents the average probability of total decrement within one year for those originally 

entitled to disability benefits who have attained that particular age. Values are derived from the average death probabilities shown in table 12 and 

the average recovery probabilities shown in table 19. See table 7C for death probabilities beyond attained age 75.

3. Time on OASDI rolls at attained age x represents the average number of future years of combined DI and OASI entitlement for those originally 

entitled to disability benefits who have attained that particular age. Values are exposure-weighted averages of expected time on the combined 

rolls across all durations from tables 23A and 23B, and reflect automatic conversion to old-age benefits upon attaining normal retirement age. 

See table 9C for expected future lifetimes beyond attained age 75.

4. Time on DI rolls at attained age x represents the average number of future years of DI entitlement for those originally entitled to benefits who 

have attained that particular age. Values are exposure-weighted averages of expected time on the DI rolls across all durations from tables 24A

and 24B. Entitlement is not considered after conversion to old-age benefits.

Notes:

1. Duration measured in years since selection.

2. Probability of death or recovery at duration t represents the average probability of total decrement 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. Time on OASDI rolls at duration t represents the average number of future years of combined DI and OASI entitlement for those originally 

entitled to disability benefits who have not died or recovered after t years. Values are exposure-weighted averages of expected time on the 

combined rolls across all ages from tables 23A, 23B and 9C, and reflect automatic conversion to old-age benefits upon attaining normal 

retirement age.

4. Time on DI rolls at duration t represents the average number of future years of DI entitlement for those originally entitled to benefits who have 

not died or recovered after t years. Values are exposure-weighted averages of expected time on the DI rolls across all ages from tables 24A and 

24B. Entitlement is not considered after conversion to old-age benefits.

V. STUDY POPULATION AND METHODS

A. Overview

This study is based on over 11.9 million records of Social 

Security Disability Insurance (DI) worker beneficiaries drawn 

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

February 2009. The 5-year observation period covers January 

1, 2001 through December 31, 2005. These records provide 

25.5 million life-years of exposure for males and 20.4 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 three main reasons for termination of disabled worker benefits are the following:

• 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 2009. 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.

Up to three separate periods of disability are examined for participants in this study. 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 select 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 three 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 beginning in 2001. 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.18

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 ;

19 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.20

E. Select 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 selection are no longer a function of select 

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, 2005

Date of birth: July 10, 1960

Actual age at entitlement: 44 years, 206 days

Insuring age: 44 years

Insuring date of birth: February 1, 1961

Use of insuring age results in an integral select age at entitlement, ensuring that subsequent durations begin on the beneficiaries 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 select 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.

21 The horizontal and vertical smoothing coefficients were chosen to obtain some degree of smoothness 

within individual durations (columns) as well as within select 

ages (rows), without deviating much from the original estimates.

G. Survival Tables

Survival tables 8A-8C are constructed from select-and-ultimate death probabilities. The values are first 

calculated for select 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 select 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 

select age. The value for is the number of lives remaining from the original who have attained age . The 

number alive at any given select or attained age is not an actual 

count of disability beneficiaries, but is the product of combining probabilities with an arbitrary radix.

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

the combined decrements of death and recovery (22A-22C) are 

constructed in the same manner. Since recovery is no longer 

considered after attaining normal retirement age, tables 15A15B are truncated after attained age 65.22

The survival tables are read across the row, or select period, for 

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

below uses numbers from table 8A for male beneficiaries disabled at select age 50.

19All 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 .

20For 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).

old-age beneficiaries no later than age 65 year 4 months (those born in 1939 or 

earlier). For beneficiaries born in 1940 or later, old-age conversion will take 

place beyond the end of the observation period (see chart in section I).

H. Expected Future Lifetime

Expected future lifetime tables are derived from the survival 

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 select age (see tables 11, 18, and 25) or attained age 

(see tables 12, 19, and 26).

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

duration of that age. This differs from the expected lifetime for 

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

of the expected future lifetime of various durations.

For example, expected future lifetime for select age 40 is a 

weighted average of the expected lifetimes shown across the 

select row and down the ultimate column. In this instance, each 

cell represents a different attained age. In contrast, expected 

future lifetime for attained age 40 is the average of the 

expected lifetimes for a select 40-year-old at duration 0, a 

select 39-year-old at duration 1,... a select 16-year-old 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 surviving 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 select 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

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 shows the present value of a whole-life annuity due and a temporary life annuity due to age 66 for a male 

worker disabled at age 50.
