FOREWORD

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

program is Actuarial Study #114, Social Security Disabiity Insurance Program Worker Experience (June 1999). The

study examined historical data with regard to disability incidence and benefit termination over the period 1975-98. 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 1991-95. The overall content of Actuarial Study #118, and the methods used to prepare

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

examined over the period 1975-2004, and a comprehensive analysis of termination activity is presented for the 5-year

period 1996-2000. 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, which appeared intermittently

in previous studies. For this information, the reader is referred to Actuarial Study #115, Short-Range Actuarial

Projections of the Old-Age, Survivors, and Disability Insurance Program (July 2001), which was developed to

provide a detailed description of the methodology and assumptions used in projecting the costs associated with the

entire OASDI program. An update to that work is scheduled to appear later this year.

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

After onset of a severe physical or mental impairment, a

worker may become entitled to monthly disability insurance

benefits under the Social Security Old-Age, Survivors, and

Disability Insurance (OASDI) program, provided he or she:

• Meets the definition of disability set forth in the Social

Security Act;

• Has filed a claim for disability insurance benefits; 

• Satisfies the disability insured requirements of the Act; 

• Has completed a 5-month waiting period; and

• Has not attained normal retirement age1

.

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 activity of disabled

workers of the Social Security Disability Insurance (DI) program as described under title II of the Social Security Act.

A. 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.

In addition, 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.

Several additional points are worth mentioning:

• The worker’s impairment must be the primary reason for

the inability to engage in SGA. 

• The formal determination of disability is based on a

sequential process defined in regulations. The first step

compares actual earnings to a specified level to determine

ability to engage in SGA. Absent such actual earnings

evidence, the sequential process continues with an

evaluation of the nature and severity of the alleged

impairment, followed by consideration of age, education,

and work experience.

• An individual age 50-59 may receive disability benefits as

a disabled widow(er) or surviving divorced spouse of a

person who died fully insured; requirements include

satisfying the same definition of disability that applies to

workers.

• Disability benefits for a disabled son or daughter age 18 or

over (childhood disability benefits) may be payable for a

disability which began before age 22; requirements

include satisfying the same definition of disability that

applies to workers.

• Special provisions exist for the evaluation of insured status

and disability in cases of statutory blindness. 

• The same definition of disability applies when

determining eligibility of adults 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).

B. 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, or have a specific amount of covered earnings in a year.

Credit for this work is measured in quarters of coverage (QCs),

or credits.

An insured status test of the number of credits earned by a

worker is required to establish a period of entitlement to any

benefit. To be considered for disability benefits, a worker must

satisfy disability insured status requirements, which consist of

having obtained a requisite number of total credits as well as a

specified number of credits earned in recent quarters. The

worker must accrue a sufficient number of credits to be

deemed fully insured—at least six credits and no more than 40

credits are required for this insured status.3

 The recency-of1 Under present law, the normal retirement age is 65 for those born in 1937 or 

earlier, and is scheduled to increase gradually—over two separate phase-in 

periods—to age 66 beginning with persons born in 1943, and age 67 beginning 

with persons born in 1960.

2 In 2005, a worker receives one credit (up to a maximum of four) for each 

$920 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. 3 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)—years that are partially or fully within a period of disability are not counted.

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 waiting period begins.

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

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

a disability which began before the quarter of attainment of age

31 satisfies the recency-of-work requirement if credits were

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 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.

C. 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 definition of disability and the disability insured requirements. 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.

II. EXPERIENCE OF DISABILITY DETERMINATIONS 

A. Substantial Gainful Activity (SGA)

Substantial work activity involves the performance of significant physical or mental duties that are productive in nature.

The degree to which an impairment limits an individual’s ability to perform basic work activities is essential in determining

the severity of the disability. Basic work activities include: sitting, standing, walking, lifting, carrying, handling, reaching,

pushing, pulling, climbing, stooping, seeing, hearing, speaking,

understanding, carrying out simple instructions, using judgment, responding appropriately in a work setting, and dealing

with changes in work routine.

Gainful work activity is work performed for pay or profit. Certain earnings criteria have been established as reasonable indications of whether an individual is engaged 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 had been 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

the level of SGA.

B. Impairments

To establish the presence of an impairment, an individual must

provide supporting medical evidence along with the disability

claim. The Social Security Administration’s Listing of Impairments is used to determine the severity of the disability. The

listings contain examples of common impairments for each of

the major body systems that are deemed to be of such severity

as to prevent a person from performing SGA. However, a diagnosis of a listed impairment alone may not be sufficient to

establish disability; associated symptoms, clinical signs, and

laboratory findings must accompany it. In addition, claimants

are asked to provide the names of employers and job duties for

the last 15 years.

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

The leading diagnostic categories for disability vary by gender

and year of award. Table 1 shows the leading causes among DI

disabled workers. Ranked by overall percentage, musculoskeletal disorders represent the largest single category of impairment, accounting for 24.4 percent of all awards over the period

1998-2002. As the baby-boom generation (birth cohorts

1946-64) continues to age, arthritic, back, and bone disorders

are expected to become increasingly more prevalent. It is anticipated that the DI program will continue to experience a growing proportion of awards in this impairment category. Also

note that the jump in the percentage of musculoskeletal impairments in 1995 can be explained by a change in reporting

method. Prior to 1995, the Office of Disability (OD) reported

the diagnosis of all awards based solely on the distribution of

allowances at the initial level. In essence, allowances at the

appeals level were assumed to have the same distribution

among impairment categories as those at the inital level. In

1995, OD began reporting the actual diagnosis of all awards at

all levels of review. This change revealed a significantly higher

percentage of musculoskeletal impairments at the appeals

level. The accompanying drop in the percentage of mental

impairments in 1995 suggests that at least some of the awards

in this category were among those misclassified under the old

reporting method.

Mental impairments rank second in overall percentage,

accounting for 23.8 percent of all awards, and continue to have

the highest percentage among females for the 5-year period

ending in 2002. Mental disorders had been the leading cause of

4 As of 2005, a blind individual earning over $1,380 per month (net of impairment-related work expenses) is ordinarily considered to be engaging in SGA. 

The comparable amount for non-blind individuals is $830 per month.

disability for both sexes until being displaced by musculoskeletal disorders in 1996. However, mental impairments became

the leading cause again in 2001. This may be due, in part, to a

special administrative initiative. Effective in that year, SSA

began conducting a review of SSI recipients who are potentially eligible for DI benefits due to previously unrecognized

disability-insured status. Many of the resulting awards were

found to be individuals under age 35 who were diagnosed with

a mental disorder. Although review of this special disability

workload is expected to continue for a number of years, the

impact on specific impairment categories is uncertain. Also

note that revised listings for mental impairments (published in

1985) led to the re-adjudication of a large number of cases,

resulting in a jump in new awards in 1986. 

Among males, circulatory disorders have always been a leading cause of disability, accounting for roughly 14-16 percent of

total awards over the last 10 years. Neoplastic disorders have

also been steady in recent years, accounting for roughly 9-11

percent of total awards. An age comparison within these two

categories reveals nearly five times as many circulatory

impairments among those age 50 or older compared with those

age 35-49; and three times as many neoplastic disorders for the

same age distribution. Although medical advancements continue in these categories, the large disparities show that these

types of impairments will continue to significantly impact the

DI rolls as the baby-boom ages. Finally, the percentage of

awards based on infectious disease has decreased significantly

over the last 5 years, mainly due to the marginalized impact of

HIV infection.

Awards based on neoplastic and metabolic impairments rank

higher among females than males, whereas awards based on

circulatory impairments rank lower. Higher prevalence of cancer, and hormonal and eating disorders, as well as increasing

prevalence of diabetes among females may account for this.

Note that 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. Determination Process

At the initial stage of a claimant’s request for disability benefits, the State Disability Determination Services (DDS) will

make a decision to allow or deny the claim. A claimant who is

dissatisfied with the initial decision may request further review.

This review process consists of several steps, which must be

requested within specified time intervals, and in the following

order:

• The claimant may request the reconsideration of an initial

decision. This entails re-examination of administrative

records, with the opportunity to submit new material

evidence supporting the claim. 

• If disagreement persists after the reconsideration, the

claimant may request a hearing before an administrative

law judge (ALJ) of the Office of Hearings and Appeals

(OHA). 

• If disagreement persists after the ALJ decision, the

claimant may request a review by the Appeals Council of

OHA, and then may pursue civil action in a Federal

district court.

Table 2 presents data on the disposition of claims for DI disability benefits across the various review stages, for calendar

years 1993-2004. The data are tabulated by year of filing, with

an additional break out 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.

Many factors exist that affect the number of disability claims

filed as well as the frequency of subsequent decisions to either

allow or deny benefits. However, the impact of any one factor

is difficult to gauge; in general, they may be administrative,

economic, or demographic in nature. Below is a list of some of

the leading determinants which may have a significant impact

on both the number of claims filed and the rate of favorable

determinations5:

• Legislative changes to the program;

• Revisions to disability guidelines or impairment listings;

• Medical advancements or breakthroughs in the treatment

of specific disorders;

• Changes in medical evidentiary requirements and

diagnostic trends;

• Technology that can enhance the ability to work;

• Actions by Federal, State, and local governments to

increase program awareness and encourage enrollment;

• Demonstration projects and initiatives that offer work

incentives to applicants in lieu of awarding disability

benefits;

• Changes in the SGA amount; 

• National health threats such as HIV; 

• Strength of national and regional economies;

• Employment shifts in part-time work or level of labor

force participation, affecting disability insured status;

• Demographic shifts such as the aging of the baby-boom; 

5 Discussed in greater detail in The Social Security Disability Insurance Program—an Analysis (Department of Health and Human Services, December 

1992).

• Level of administrative funding and the ability to control

current caseloads and backlogs;

• Public pressure on program policy, which may lead to

changes in regulations or legislative action; 

• Level of court involvement in the appeals process; 

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

interpretation of the law.

D. Applications

The number of DDS claims for DI disabled worker benefits

declined steadily from 1.25 million in 1994 to 1.04 million in

1998. Some factors contributing to the decline in this period

include a robust economic expansion and lower levels of

unemployment; leveling off of female labor force participation; a decline in HIV-related impairments; and the elimination

of drug addiction and alcoholism as material causes for disability.

Over the following 6 years, the DI program experienced nearly

a 43 percent increase in applications to an estimated 1.49 million in 2004, with roughly a 10 percent increase alone in each

of 2001 and 2002. This increase in DDS claims is not fully

understood, except in general terms. Having an obvious impact

is the aging of the baby-boom, which continues to progress

through the peak ages of disability; and higher levels of unemployment resulting from the economic contraction which

began in the second quarter of 2001. A small portion of additional claims come from the review of the special disability

workload of SSI recipients who may be eligible for DI benefits, as previously mentioned.

E. Initial Decisions

From 1992 through 1995, the allowance rate declined even as

application growth continued. This may be indicative of claimants—caught in the economic downturn of a post-recession

period—exhibiting less severe impairments. The result was

fewer allowances from a growing number of claims. 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. Many times the only alternative is to seek aid from

Federal, State, or local programs. Consequently, concurrent filers may exhibit less severe disability, or provide less evidence

of impairment, resulting in fewer allowances.

Also note that for years with pending decisions, the ultimate

allowance rate will be lower than that shown in table 2. This is

due to the greater processing time involved in unfavorable

decisions.

F. 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.

Currently 10 States are participating in a test of the Prototype

Model to redesign the disability determination process. Features of this model include elimination of the reconsideration

step, along with use of a single decision-maker and process

enhancements at the DDS and OHA levels. The results shown

in table 2, therefore, reflect a mixture of experience for the

standard decision model and the modified test process. The

Prototype Model test is set to expire on December 31, 2005.

G. Appeals Beyond Reconsideration

The subjectivity inherent in assessing disability leaves considerable room for interpretation of evidence. As a result, overturned decisions at the OHA level and beyond remain

relatively high. Factors that contribute to the high reversal rate

include:

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

the initial and reconsideration stages;

• Worsening of alleged disability 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.

Class action suits can also have an impact on the determination

process. Public pressure has surfaced in controversial areas

such as mental impairment issues; the amount of leverage

given to allegations of pain; statements by treating physicians

in the absence of clinical evidence; how HIV-related impairments and cardiovascular diseases are evaluated; use of vocational factors in the absence of a single debilitating

impairment; and the consistency of DDS decisions with SSA

policy. Although the number of claimants directly involved in

any one case may not be large, the outcome may have a

broader and subtler influence on subsequent rulings and determinations.

Finally, Federal efforts aim to improve the disability determination process by striving to reach the proper determination at

the earliest possible stage. This effort will help to maintain

managable backlogs, as well as reduce the rate of overturned

decisions at the OHA level.

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

to the initial decision.

III. EXPERIENCE OF DISABILITY INCIDENCE

A. History

Since the commencement of disability cash benefits in July

1957, dynamics of the DI program have been subject to many

internal and external factors. Congressional action, public

opinion, and court rulings have shaped program characteristics

including: how disability is defined; the determination of entitlement; the level of benefits; the review process of current

beneficiaries; and ultimate program cost. 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. From 1968 through 1970, disability

incidence remained fairly stable; however, through the early

1970s program growth far exceeded any reasonable expectations.

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 disability

claims. In addition, administrative policy also tended to change

as the DI program became bigger and more complex. Notably,

the SSI program generally requires applicants under the age of

65 to apply for benefits from all other programs including DI,

which may partially or fully offset SSI benefits. As expediency

in processing applications was naturally given high priority,

central office review of DDS initial decisions fell to roughly

5 percent in 1972 from 100 percent prior to 1972. The

increased public awareness and pressures of administering two

new programs probably contributed significantly to the sharp

increase in new awards from 1972 to 1976. 

The Social Security Amendments of 1977 (Public Law 95-216)

and the Social Security Disability Amendments of 1980 (Public

Law 96-265) also had a significant impact on the DI program.

The 1977 amendments changed the benefit formula used to

calculate benefits awarded in 1979 and later. The 1980 amendments introduced a more restrictive limit on the total monthly

amount of Social Security benefits payable on a disabled

worker’s account; and mandated a 65 percent review rate of

DDS allowances to assure uniformity of decisions. The return

to high levels of review during this period led the DDSs to give

increasingly careful consideration to new allowances, and

increased the chances of reversing an initially favorable decision. These circumstances contributed to steadily declining

awards from 1977 through 1982.

By 1984, DI program policy had undergone another reversal.

Congressional and public concern over the removal of a large

number of beneficiaries (particularly the mentally impaired)

resulted in an administrative moratorium on the review of the

disability rolls while Congress considered new DI legislation.

Many beneficiaries whose benefits had been terminated were

returned to the rolls through the appeals process. This initiated

a period of increased court appeals and class action suits. In

response, 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.

B. Recent Experience

Table 3 shows the total number of DI disabled workers

awarded benefits grouped by calendar age7

 at time of award,

for calendar years 1980-2004. These awards are 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

expressed as age-adjusted (male and female) or age-sexadjusted (total) relative to 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.

7 Calendar age is the integral age attained on the birthday in the year in which 

the individual is awarded benefits.

The incidence of disability increases considerably among

workers beginning at age 50. The chance of DI entitlement

increases naturally with advancing age, but also as a result of

greater consideration given to vocational factors. This program

characteristic continues to have a significant impact on costs as

the baby-boom generation progresses through ages of higher

incidence. Note that the rates shown in table 4 for ages 60 and

older are likely to understate the true incidence of disability

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: the disability waiting period (old-age benefits are

payable immediately); the potential for worker’s compensation

offset; differences between disability and old-age maximum

family benefits payable; and the possibility for denial of disability benefits.

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 five years, the decline is more pronounced among males. This is likely due to the elimination of

drug and alcohol addiction from the DI rolls 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 necessarily

translate into a decline in the number of benefits awarded in

this specific age range. This is due to the relatively large

increases in female labor force participation. Over the 10-year

period ending in 1996, labor force participation rates among

females age 35-54 increased between 3.5-10.0 percentage

points resulting in an additional 10.7 million disability insured.

Over the same period and 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, the decline in

incidence between 1975-82 is attributable, in part, to a stricter

program. Following a very low-growth 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. In the late 1990s, the

prevailing economic and political environment was characterized by robust economic expansion, low unemployment, and

legislative restrictions on the qualifications of certain impairments. In addition, advancements in medical treatment; public

need for employer-sponsored healthcare protection; and pursuit

of financial goals for retirement may have provided incentive

to remain in the labor force, if possible. These factors contributed to the decline in applications and awards during this

period.

The sharp increase in incidence rates over 2001-04 represents a

notable departure from the experience of the late 1990s, which

generally showed modest annual declines in the age-sexadjusted 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. However, special administrative activity by SSA beginning in 2001 has also contributed slightly to the surge in awards. As previously mentioned,

the special disability workload was the result of discovering a

substantial number of SSI recipients whose disability-insured

status was not previously recognized. As this caseload is processed over the next several years, the resulting disability

awards will contribute to temporarily higher incidence rates

than would be expected from current underlying trends.

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 current-payment status, at the end of calendar years 1980-2004. The current-payment population is derived from the in-force

beneficiary population (not shown), which is reduced by the

number of entitled individuals whose benefits are suspended.

Common reasons for the suspension of DI benefits include:

engagement in SGA following completion of a trial work

period; worker’s compensation offset; or imprisonment. Over

the period 1983-2004, the current-payment population has

grown at an average annual rate of roughly 4.3 percent, as

growth in awards has steadily outpaced growth in terminations.

Note that as a consequence of the scheduled increase in normal

retirement age, there appear DI beneficiaries age 65 or older

for the first time in 2003. The following table summarizes the

progression of the DI rolls.

IV. EXPERIENCE OF DISABILITY BENEFIT TERMINATION 

A. Background

The reasons for termination of DI disabled worker benefits can

be grouped into four main categories:

• Death of the beneficiary; 

• Recovery—beneficiary no longer meets the standards used

to define disability, including medical recovery or return

to work;

• Conversion—disability benefit is converted to an old-age

benefit upon attaining normal retirement age; and

• All other reasons8.

Generally, the final month of entitlement to disability benefits

for a worker is the earliest of the following:

• The month before the month in which the worker dies;

• The month before the month in which the worker attains

normal retirement age; or 

• The second month after the month in which the

beneficiary recovers9

. 

The law contains several provisions for individuals who wish

to return to work, but continue to have a disabling impairment:

• Trial work period; 

• Extended period of eligibility; 

• Extension of Medicare coverage;

• Expedited reinstatement; and

• Waiver of the waiting period.

The trial work period (TWP) is a 9-month period—not necessarily consecutive—during which an entitled beneficiary may

work without affecting the right to benefits. Earnings during

the 9 months are not counted toward SGA, and benefits will

continue as long as the beneficiary has not medically recovered.

Individuals who continue to have a disabling impairment following the 9-month TWP, receive an extended period of eligibility (EPE). Earnings during the EPE are counted toward

SGA, and monthly benefits will not be paid when such earnings exceed the SGA limit. If earnings fall below the SGA

limit anytime during the EPE, benefits are automatically reinstated. Effective January 1, 1988, the law was amended to

lengthen the EPE from 15 months to 36 months for individuals

entitled to benefits in January 1988 or later.

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 and

Work Incentives Improvement Act of 1999 (Public Law 106-

170)—effective October 1, 2000, coverage for beneficiaries

who return to work will continue for an additional 4 1/2 years

beyond the EPE.

The Ticket to Work Act also allows certain previously entitled

individuals to request expedited reinstatement (EXR) of disability benefits when a disabling impairment no longer permits

the performance of SGA. The provision provides a safety net

for those who successfully return to work and, consequently,

lose entitlement to disability benefits. EXR allows an individual to request reinstatement without filing a new application,

and provides up to 6 months of provisional (temporary) cash

benefits while SSA conducts a medical review to determine

whether the individual can be reinstated. The request for reinstatement must be filed within 5 years of the termination of disability benefits. EXR became effective January 1, 2001.

Special provisions are granted to persons experiencing multiple periods of disability. Individuals who become re-entitled to

benefits 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 time may accrue over

multiple periods of disability.

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

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

disabled beneficiaries elect to receive DI benefits until normal

retirement age—at which time conversion to benefits payable

under the Old-Age and Survivors Insurance (OASI) program

occurs automatically—some choose to switch earlier. This

decision is influenced by economic as well as personal factors.

One of the most common reasons is the existence of benefits

payable outside the DI program. For example, worker’s compensation benefits may partially or totally offset a DI benefit,

but would not affect an OASI benefit. Another common economic factor is the difference in maximum family benefits payable under the DI program, which may be lower than the

maximum payable under the OASI program. Personal factors

may include the beneficiary’s own assessment of health and

life expectancy.

Recovery from disability may occur when the beneficiary

either notifies SSA of an improved disabling condition, demonstrates the ability to engage in SGA, or is judged to no

8 Reasons for termination in this category include: beneficiary converts to oldage benefits prior to normal retirement age; withdrawal of application; or erroneous entitlement.

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

longer meet the definition of disability. The DDS or the central

office will conduct a continuing disability review (CDR) from

time to time based on warranting situations such as:

• Maturing of a scheduled CDR diary date;

• Posting of substantial earnings10; or

• Voluntary or vocational rehabilitation reports of an

improved disabling condition.

Certain “outside” variables such as disability caseloads, backlogs, budget restrictions, and legislation can have an impact on

CDR activity and disability recovery rates in general, without

actually affecting the underlying rate of medical improvement.

These factors shape the prevailing administrative policy and

can exert considerable influence on the nature of allowances,

and the degree of overall impairment-severity of the DI rolls.

To a lesser extent, mortality rates are also affected by exogenous variables. For example, the elimination of drug and alcohol related impairments, and an increase in allowance based on

vocational factors or mental impairments may lead to an

improvement in the overall mortality profile of the DI rolls.

B. History

Many variables can affect the rate at which beneficiaries are

terminated from the disability rolls, including:

• Overall improvements in disability mortality;

• Advancements in medical treatments and technology

which enhance the ability to work;

• Changes in regulations that affect the makeup of the rolls;

• CDR activity;

• Vocational rehabilitation support and return-to-work

incentives; 

• Court decisions and the level of legal representation and

appeal.

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

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

less seriously impaired claimants and lower mortality rates

among the disabled. The 1967 amendments eased the insured

status requirements for claimants under age 31. A growing portion of younger and relatively healthier beneficiaries further

contributed to the decline in the mortality rates of the DI rolls.

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

gross recovery rate generally increased. With the introduction

of government-funded rehabilitation programs, elimination of

the “permanently disabled” condition, and the extension of

benefits to younger claimants, the recovery rate among beneficiaries rose from 19 per thousand in 1965 to 32 per thousand

by 1967. Thereafter, the gross recovery rate decreased rapidly

through 1975. This was 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 DDS continuances

in which medical recovery was expected. Previously, 100 percent of such continuances were reviewed. By 1976, the gross

recovery rate began to increase again as central office review

of continuances returned to 100 percent.

Throughout the 1970s, the DI program experienced substantial

increases in cost, mainly the result of significant growth in

incidence. Under then-current policy, reviews were performed

only in those cases where the beneficiary’s condition was

expected to improve, or voluntary reports or posted earnings

indicated work activity. However, by the late 1970s measures

to curtail inaccurate award determinations and improve the

review process were intensified. One 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 Reagan Administration initiated a major review of the

disability rolls that resulted in a large number of cases in which

it was determined that recovery had occurred.

Ensuing public disapproval of the newly implemented review

process led to a moratorium on reviews of all cases of mental

impairment disability.11 Revision of mental impairment criteria

and the review process followed and more than half of those

removed from the rolls were reinstated upon appeal. The result

was a sharp drop in recoveries as well as a sharp increase in

new awards throughout the remainder of the 1980s.

C. Recent Experience

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

early 1990s, there existed a shortage of personnel needed to

handle a significant increase in claims, as well as to meet

review schedules. In an effort to free up resources to process

initial claims, the agency sharply curbed the review of existing

beneficiaries. Beginning in 1994, growth in initial claims

began to level-off and once again attention shifted to performing mandated reviews. 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. As

intended, the special funding helped to eliminate DI backlogs

10 The aforementioned Ticket to Work Act 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 basis for review. Provisions are effective 

January 1, 2002.

11 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.
10

by the end of 2000, and to become essentially current in the

processing of SSI-only CDRs by the end of 2002. Since then,

administrative budget delays have caused the agency to fall

behind in processing certain SSI CDRs, emphasizing the need

for renewed funding and revised scheduling plans.

Table 5 shows the historical number of terminations and gross

termination rates for disabled workers, by reason for decrement. As evident from the data, most terminations occur as a

result of death or conversion. With the exception of a sharp

decrease in conversions in 200312, both categories exhibit

steady long-term trends with little variation from year-to-year.

In contrast, the number of recoveries can deviate considerably

from a somewhat normal level. As previously mentioned,

exogenous variables can greatly impact this category—and

consequently the recovery rate—without actually affecting the

underlying rate of medical improvement. As an example, we

see that a spike in recoveries occurred in 1997 as the result of a

provision of Public Law 104-121, which eliminated drug and

alcohol addiction from the impairment listings and explicitly

denied benefits in cases where drug or alcohol addiction were

contributing material factors to the disability. Although categorized as “recoveries”, this group of beneficiaries was simply

eliminated from the rolls due to a change in law. “Other” is a

relatively small category comprised mostly of individuals who

switch to old-age benefits prior to normal retirement age. Figure 3 shows the distribution of DI disabled worker terminations by reason.

As mentioned, death and conversion account for most of the

terminations that occur, and the general trend in termination

rates has been downward. Figure 4 shows the distribution of

DI disabled worker termination rates by reason. Several trends

in the disability rolls have developed over the years which help

explain the decline: mortality improvements and a reduction in

the average age of beneficiaries.

Over the period 1980-95, the average age among male disabled

workers in current-payment status steadily declined from 52.8

to 49.8 years. The proportion of the DI rolls made up of beneficiaries aged 35-49 grew from 20 percent in 1980 to 34 percent

in 1995, while the proportion of 50-64 year olds fell from 71

percent to 55 percent. Similar trends were experienced among

female disabled workers as the average age declined from 53.7

to 49.9 years. Higher incidence of mental disorders has led to

an increase in younger and (physically) healthier beneficiaries.

The result is fewer deaths, as well as a smaller percentage of

beneficiaries converting to old-age benefits each year.

Since 1995, the average age among disabled workers in current-payment status has steadily increased. In 2004, the average age of disabled males was 51.6 years. The proportion of

the DI rolls made up of beneficiaries aged 35-49 declined

slightly to 29 percent, while the proportion of 50-64 year olds

grew to 62 percent. Similar trends were experienced among

female disabled workers as the average age climbed to 51.4

years. Note that the increase in average age is mostly an effect

of the aging baby-boom generation and has not yet resulted in

any significant increase in conversions. The trend in termination rates continues to be downward, in large part due to mortality improvements, as well as the scheduled increase in

normal retirement age.

Medical progress has significantly contributed to longer life

expectancy among the general population. Certain advancements have also had a considerable, albeit less quantifiable,

impact on selected segments of the disability population. Over

the period 1980-89, the DI rolls show gross rates ranging from

roughly 50-55 deaths per thousand males, and 35-40 deaths per

thousand females. Throughout the early 1990s, mortality grad12 This decrease is attributable to the scheduled increase in normal retirement 

age, resulting in the deferral of a portion of old-age conversions from 2003 to 

2004.

ually improved. A noticeable decline in the death rate after

1995, especially among males, is due in part to the rapidly

diminishing impact of HIV-related impairments and the elimination of drug and alcohol addiction from the impairment listings. Other significant trends leading to a lower mortality

profile of the disability rolls include: increasing prevelance of

musculoskeletal and mental impairments, which tend to be less

life-threatening than circulatory or neoplastic disorders;

advancements in the treatment of malignant growths; and a

greater proportion of awards to older workers, whose determinations are based on a set of vocational factors rather than a

single severe disability. Over the period 2000-04, the DI rolls

show stable gross rates of roughly 35 deaths per thousand

males, and 26 deaths per thousand females.

D. Death Experience (1996-2000)

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, 1996 through December 31, 2000. The methods

used in table construction and graduation are detailed in the

appendix.

Mortality among disabled workers generally increases with

select age. 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 is lowest at these durations before trending upward in the later durations as general

demographic factors such as age of the beneficiary begin to

have an increasing effect. Greater consideration given to vocational factors, especially after age 50, may cause a slight

decline in mortality. Disability mortality among males is higher

than females for virtually all attained ages. Unique data considerations affecting estimates of disability mortality—such as

death during the waiting period and tracking DI beneficiaries

upon conversion to old-age benefits—are discussed in the

appendix.

An analysis of broad age categories may explain some of the

trends and characteristics of disability mortality. Disabled

males under age 35 show the highest concentration of mental

disorders, infectious and nervous impairments, and injuries.

Disabled males aged 35-49 show a consistent mix of various

impairments following the predominant mental and musculoskeletal categories; an increase in circulatory and neoplastic

impairments is apparent. Disabled males aged 50 or older show

the highest concentration of musculoskeletal awards, along

with considerable increases in circulatory, neoplastic, and respiratory disorders; though still an important category, the prevalence of mental impairments is down considerably from the

younger age groups.

Females show comparable trends in broad age categories with

a few categorical changes. Disabled females under age 35

show the highest concentration of mental disorders—over 43

percent of new awards occurred in this category in 2002. Disabled females aged 35-49 continue to show high incidence of

mental and nervous impairments, along with large increases in

musculoskeletal and neoplastic disorders. Disabled females

aged 50 or older show the highest prevalence of new awards in

the musculoskeletal, mental, and neoplasm categories.

Due to the many reasons already discussed, disability mortality

over the 5-year period covered in this study (1996-2000) has

improved for roughly 80 percent of all attained ages among

male and female beneficiaries, when compared to the previous

5-year period (1991-95)13. Among males, mortality in the

more recent period is generally 5-20 percent lower than mortality in the earlier period, with dramatic reductions of 35-45 percent at some younger select ages. The improvements at the

younger ages are largely due to advancements in HIV treatment and legislation eliminating drug and alcohol addiction

from the impairment listings. Mortality improvement among

females is as widespread but less dramaitic as that seen among

males, generally ranging from 5-15 percent lower than the earlier period.

Tables 8A-8C show the progression of a series of cohorts—

each for a given select age—reflecting the probabilities of

death shown in tables 7A-7C. These survival tables are a concise way of representing the probabilities of a particular population living to a particular age. See appendix for details on

table construction and usage.

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

workers. Values are based on the survivorship experience

shown in tables 8A-8C. As with the general population, disabled females display a higher future lifetime than males. Note

that life expectancy is generally greater during the second or

third year of entitlement than during the first year of entitlement. This is due to relatively higher mortality rates within the

first several years of disability, after which workers seem to

show a greater propensity for disability continuation or nondeath termination.

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

entitled disabled workers. These rates are derived from the

probabilities of death shown in tables 7A-7C, and represent a

different concept in measuring the rate of termination from the

DI rolls. Absolute rates consider only the effect of a single decrement in a multiple-decrement environment, reflecting the

probability of survival and ultimately termination under that

one decrement. These are not true probabilities and as such are

expressed on a “per thousand” basis. See the appendix for further details.

13 Findings are based on comparisons with disability mortality as discussed in 

Actuarial Study No. 114: Social Security Disability Insurance Program Worker 

Experience (Zayatz, June 1999).
12

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 within one year for beneficiaries originally entitled at a

particular select age (table 11), or who have attained a particular age (table 12). Similarly, aggregate future lifetime represents the average life expectancy of beneficiaries for a

particular select or attained age. Values are exposure-weighted

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

tables 9A-9C.

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 of entitlement to disability benefits. Aggregate future

lifetime represents the average life expectancy of beneficiaries

who have been entitled for the stated number of years.

E. Recovery Experience (1996-2000)

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

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

For any particular select age, the probability of recovery exhibits a bimodal distribution. Disability recovery tends to peak

during the second year of entitlement before declining the following year, then peaks again at its maximum level in the fifth

year of entitlement before declining thereafter. This effect is

likely caused by CDR schedules, which are based on the likelihood of medical improvement. Beneficiaries for whom medical improvement is expected (MIE) account for roughly 5-10

percent of all reviews, which are scheduled anywhere from 6 to

24 months following the most recent disability decision.

Roughly 10.5 percent of MIEs result in an initial cessation

(i.e., those occurring before any appeal of decision) of benefits,

causing the first peak in recoveries. Beneficiaries for whom

medical improvement is possible but less likely to occur within

the first 2 years (MIP) account for roughly 65-70 percent of

reviews, which are scheduled every 36 months. Roughly 8.5

percent of MIPs result in an initial cessation of benefits, causing the second peak in recoveries. Beneficiaries for whom

medical improvement is not expected (MINE) account for

roughly 25-30 percent of reviews, which are scheduled every 5

to 7 years. Roughly 4.5 percent of MINEs result in an initial

cessation of benefits.

As previously stated, the probability of death among males

exceeds that for females for virtually all attained ages, as males

experience nearly twice the incidence of high risk circulatory

disorders and two-thirds more injuries. The probability of

recovery among males also exceeds that for females in over 85

percent of all attained ages. Evidence suggests that this may be

due to differences in the concentration of impairment categories among genders, especially at older ages. During the observation period, both sexes exhibit high prevalence of mental and

musculoskeletal impairments. However the relative concentration of mental impairments among females is much greater—

18 percent higher overall, and 25 percent higher among ages

50 or older. The nature of these types of impairments seems to

contribute to both lower mortality and lower chance of recovery among female disabled workers.

Analysis of the 5-year period covered in this study shows a

dramatic increase in the rate of disability recovery for virtually

all male and female beneficiaries, when compared to the previous 5-year period (1991-95)14. For males, most ages exhibit a

50-100 percent increase in the probability of recovery, while

females show increases ranging from 25-75 percent. A disproportionate amount of the improvement is attributable to the

elimination of beneficiaries whose disability was based on

drug or alcohol addiction, causing a one-time spike in recoveries in 1997. That year, the overall recovery rate among males

more than doubled to 27 per thousand entitled versus 12 per

thousand in the prior year. Females also experienced a surge to

16 per thousand versus 10 per thousand in the prior year.

As previously mentioned, exogenous variables can also influence recovery rates. During 1991-95, the DI program experienced significant growth in claims, which limited the number

of CDRs performed over that period. This trend was reversed

through enactment of Public Law 104-121 in 1996, which provided special funding for CDR activity, and contributed significantly to the large increase in recoveries over 1996-2000.

Tables 15A-15B show the number of lives for a series of

cohorts—each for a given select age—reflecting the probabilities of recovery shown in tables 14A-14B. Note that in this

case, the concept of “survival” refers to beneficiaries who

remain on the DI rolls by not recovering.

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

disability entitlement for those who have not recovered and

remain on the DI rolls. Values are based on the survivorship

experience shown in tables 15A-15B, which reflect termination

due to recovery only, and automatic conversion to old-age benefits upon attaining normal retirement age. As previously discussed, males tend to exhibit a greater chance of recovery than

females. Analysis shows that, on average, females remain on

the disability rolls roughly 6 months longer than males.

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. See the

appendix for details on the derivation of these rates.

14 Findings are based on comparisons with disability recovery as discussed in 

Actuarial Study No. 114: Social Security Disability Insurance Program Worker 

Experience (Zayatz, June 1999).
13

Tables 18 and 19 show the aggregate probability of recovery

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

Probabilities are based on aggregate counts of exposure and

recoveries across all durations. They represent the average

probability of recovery within one year for beneficiaries originally 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 for those who remain on the rolls. These values are

exposure-weighted averages of the values shown in tables

16A-16B, which reflect termination due to recovery only, and

automatic conversion to old-age benefits upon attaining normal

retirement age.

Table 20 shows the aggregate probability of recovery and

expected time on the DI rolls, by duration. 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 of entitlement to disability benefits.

Expected time on the DI rolls represents the average number of

future years of entitlement—reflecting termination due to

recovery only—for those who have not recovered after the

stated number of years.

F. Combined Experience (1996-2000)

Tables 21A-21B show the combined probability of death or

recovery for male and female DI disabled workers, by select

age and duration. Values are derived from death probabilities

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

tables 14A-14B.

Tables 22A-22C show the number of lives for a series of

cohorts, reflecting termination from DI entitlement due to

death or recovery. The tables also reflect termination from

OASI entitlement due to death, following conversion to oldage benefits.

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

combined DI and OASI entitlement for those originally entitled to disability benefits. Values are based on survivorship

experience shown in tables 22A-22C, which reflect automatic

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

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

DI entitlement for those who have not died or recovered. Values are based on survivorship experience shown in tables 22A22B. Entitlement is not considered after conversion to old-age

benefits.

Tables 25 and 26 show the aggregate probability of death or

recovery and expected time on the beneficiary rolls, by select

and attained age. Values are derived from the average death

and recovery probabilities discussed previously. They represent the average probability of total decrement within one year

for beneficiaries originally entitled at a particular select age

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

Aggregate expected time on the OASDI rolls represents the

average number of future years of combined entitlement for

those originally entitled to disability benefits. These values are

exposure-weighted averages of expected time on the combined

rolls shown in tables 23A-23B, and reflect automatic conversion to old-age benefits upon attaining normal retirement age.

Aggregate expected time on the DI rolls represents the average

number of future years of disability entitlement. These values

are exposure-weighted averages of expected time on the DI

rolls shown in tables 24A-24B. Entitlement is not considered

after conversion to old-age benefits.

Table 27 shows the aggregate probability of death or recovery

and expected time on the beneficiary rolls, by duration. Values

are derived from average death and recovery probabilities, and

represent the average probability of total decrement within the

next year of entitlement. Aggregate expected time on the

OASDI rolls represents the average number of future years of

combined entitlement for those originally entitled to disability

benefits who have not died or recovered after the stated number of years. Aggregate expected time on the DI rolls represents the average number of future years of disability

entitlement for those who have not died or recovered after the

stated number of years.

G. Annuity Tables

Tables 28A-31D show the present value of a stream of payments to a disabled worker, by select age at entitlement.

Annual or monthly payments are made at the beginning (annuity-due) or end (annuity-immediate) of each period. Receipt of

payment is contingent upon survival to the next payment date.

Note that “survival” denotes remaining entitled to benefits,

which may imply not recovering as well as not dying. Payments are discounted using the stated annual effective interest

rate and various survivorship assumptions. Tables 28A-29D

show the actuarial present value of a life annuity of $1 payable

to a disabled worker. Values are based on survivorship experience shown in tables 8A-8C, which reflect termination due to

death only, and automatic conversion to old-age benefits upon

attaining normal retirement age. Tables 30A-31D show the

actuarial present value of a life annuity of $1 payable to a disabled worker until age 65. Values are based on survivorship

experience shown in tables 22A-22B, which reflect termination

due to death or recovery.

Table 2.—Disposition of Worker Applications for Disability Benefits, by Level of Review

(Break out by program involvement and calendar year of filing1, 1993-2004 Social Security DI disability experience)

1 Data for claims filed in 1993-2003 reflect results as of June 2004 (DDS level) or August 2004 (OHA level). The number of total claims filed for 2002-03 are subject to change. Data for claims filed in 2004 are preliminary 

estimates as of January 2005. The ultimate number of allowances and denials are subject to change until all initial decisions have been completed and all appeals are final.

To recon To OHA4

4 Cases appealed directly to OHA under Prototype Model—currently being tested in 10 States—which eliminates reconsideration step in disability determination process.

Percent5

5 Number of appeals as a percentage of denials at this level. For years where decisions are still pending, the preliminary percentage shown could change substantially as all claims are processed.

Number Percent3 To OHA6

6 Number of persons appealing beyond the reconsideration level.

Percent5 Pending7

7 Includes cases remanded to OHA from the Federal courts.

Number Percent8

8 Number of allowances as a percentage of decisions at this level. For years where decisions are still pending, the preliminary percentage shown will ultimately be lower as all cases are processed. This is true since allowances are generally processed more quickly than denials

Denials9

9 Includes denied claims where the final administrative action was a dismissal of an appeal request (for example, the appeal was not filed timely or the applicant failed to appear at the scheduled hearing).

Death Experience

by Select Age and Duration

(1996-2000)
.

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 74.

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 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 7A. 

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 8C for attained ages beyond age 74.

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 7B. 

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 8C for attained ages beyond age 74.

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 7A and recovery probabilities shown in table

14A. See appendix for details.

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

table 10C for attained ages beyond age 74.

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 74.

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. 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 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.

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 15A, 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 7A and recovery probabilities shown in table

14A. See appendix for details.

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

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. 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 74.

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 74.

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

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 21A and 21B.

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 74.

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 74.

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 74.

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

For this study, we analyzed over 9.9 million records of Social

Security Disability Insurance (DI) worker beneficiaries from

the 5-year period January 1, 1996 through December 31, 2000.

Data are based on a 100 percent sample from the Social Security Administration Master Beneficiary Record (MBR). The

primary variables of interest include: the reason for decrement

from the disability rolls, and duration since entitlement. However, factors other than time since selection affect survival.

These include the standard concomitant variables of select age

and sex of the beneficiary. The analysis reflects a total of

roughly 21.9 million life-years of exposure for males and 15.6

million life-years of exposure for females. A 10-year select

period was chosen for this study, implying that decrement for

participants 10 or more years beyond selection is no longer a

function of select age, but a function of attained age only.

Termination of DI benefits can occur for the following reasons:

• Death of the beneficiary; 

• Recovery—includes medical recovery or return to work;

• Converting to old-age benefits; and

• All other reasons.

Terminations due to “all other reasons” are treated as withdrawal from the study, and directly affect exposure. However,

separate decrement tables are not developed for categories

other than death and recovery. The table below provides a

count of the number of deaths and recoveries collected from

the MBR. Note that there exist differences in classifying various disability actions among the various data sources consulted

for this study. Further note that to a certain extent, this study

also covers the activity of the OASI rolls, but only as it relates

to tracking disabled beneficiaries who have voluntarily

switched to OASI benefits prior to normal retirement age, or

have automatically been converted to the OASI rolls upon

attaining normal retirement age. As a result, termination counts

stated here will differ from those stated elsewhere—the number of deaths will be dramatically different as they include substantial counts from the OASI rolls.

Source: MBR database as of March 2004. Results do not include old-age

conversions or terminations due to other reasons.

B. Data Considerations

The mortality experience is affected by several unique circumstances. It is recognized that a claimant may die during the 5-

month waiting period required under the DI program—and

therefore never becomes entitled; or the claimant may die

before final disposition of the disability claim—in which case

only retroactive disability benefits may be payable. With

regard to the DI program, participation in this study is contingent upon entitlement to benefits. Therefore, death prior to

entitlement is not a “countable” death. As a result, the probability of death during the first year of entitlement may be artificially lower than expected.

As it relates to this study, observation ends with the termination

of benefits. Under the DI program, disabled workers may convert to old-age benefits at anytime beginning with age 62, with

mandatory conversion taking place at normal retirement age.

Such conversion is considered a termination of disability benefits as old-age benefits become payable from the OASI Trust

Fund. However, disabled beneficiaries continue under observation in this study beyond the time of the switch. Consequently,

deaths for attained ages 62 and older may come from the OASI

rolls. Note that this is a material change from methods used in

the previous DI Worker Experience study (Actuarial Study No.

114), which terminated observation with the last month in

which DI benefits are payable. This enhancement allows tracking disabled lives into retirement, and further eliminates much

of the “guesswork” involved in applying the cumbersome

blending techniques used in that study for older attained ages.

Hopefully the result is more robust estimates of mortality.

Mention was made earlier of a special disability workload of

SSI recipients who are potentially eligible for DI benefits due

to previously unrecognized disability-insured status. This

workload has 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, the cases

involved at the time of completion of this study represent a

biased sample of records. Consequently, these cases have been

eliminated from the overall sample.

C. Data Collection

The model for this study utilizes a customized database that is

constructed from 100 percent MBR data as of March 2004.

The general record selection criteria are outlined below. The

final data was subjected to numerous screenings and categorizations. Included in the study are: 

• Primary claimants (workers) entitled to disability benefits

sometime during the observation period;

Number of Disabled Worker Terminations, by Reason

(January 1996-December 2000)

Reason Male Female Total

Death 1,106,045 577,988 1,684,033

Recovery 176,760 101,080 277,840

Total 1,282,805 679,068 1,961,873
88

• Primary claimants entitled to old-age benefits sometime

during the observation period, who either voluntarily

switched from the DI rolls to the OASI rolls prior to

normal retirement age, or were automatically converted

upon attaining normal retirement age;

• A maximum of three periods of disability for each primary

having multiple periods of disability.

Excluded from the study are: 

• Dependents (spouses and children) of a primary claimant;

• Primary claimants whose period of disability was

terminated or permanently suspended prior to January 1,

1996; or whose entitlement period begins after December

31, 2000;

• Periods of entitlement to old-age benefits that were

preceeded by a period of disability which ended prior to

OASI entitlement.

D. Methods

The availability of complete data on each participant in the

study (including date of birth, date of entitlement, and cause of

decrement) allows for direct estimation of the multiple-decrement probabilities , where represents the cause of decrement. The ordered pair is determined for each age

interval for which a participant is under observation.

The concept is that each participant enters the interval at age

, and is scheduled to exit the interval at age

. Numerically, is the amount of time

(measured in life-years) that the participant is exposed to the

risk of decrement. Summing over all participants, we can calculate the scheduled exposure contributed to an interval.15

A participant may survive to the end of an interval, or may exit

the study prior to the end of the interval in the event of:

• Death;

• Recovery or other non-death decrement;

• The end of the observation period—termed an 

observed ender.

Based on these criteria, a scheduled ending age, , is established for an age interval in which the participant is expected to

either survive to the end , or become an observed ender

.

16 Scheduled exposure is then credited to the appropriate interval (or duration since selection) using the following

conditions: if the participant survives to the end of the interval,

then exposure is credited from to ; if the participant

dies or is an observed ender within the interval, then exposure

is credited from to ; if the participant withdraws

from the study during the interval (for example, recovers), then

exposure is credited from age to . Note that since

recovery from disability is no longer considered after converting to old-age benefits, a slight modification to this method is

needed in crediting exposure for use in calculating recovery

probabilities. As before, scheduled exposure is credited to

durations entirely within a period of DI entitlement, however,

exact exposure is credited only up until time of the switch to

old-age benefits; no exposure is credited for durations entirely

within a period of OASI entitlement.

Multiple-decrement probabilities are found by dividing the

observed number of deaths or recoveries in an interval by the

aggregate scheduled exposure for that interval. As discussed

later, single-decrement (absolute) rates are derived from the

probabilities using a constant force assumption for the distribution of decrement within a given interval.17

E. Select Age and Exposure

Entitlement to disability benefits usually occurs at some fractional age of the beneficiary. To facilitate exposure calculations, the insuring age of the participant and corresponding

insuring date of birth are substituted for the actual age at entitlement and actual date of birth. In this study, the insuring age

is calculated to be the beneficiary’s age last birthday as of entitlement. For example, consider the following beneficiary data:

Date of entitlement: 1-February-2000

Date of birth: 10-July-1960

Actual age at entitlement: 39 years, 206 days

Insuring age: 39 years

Insuring date of birth: 1-February-1961

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

For selection during the observation period, the entry age (YI)

into the study is the beneficiary’s age as of the date of entitlement. For selection prior to the beginning of the observation

period, the entry age is the beneficiary’s age as of January 1,

1996. In either case, the beneficiary’s age is measured from the

insuring date of birth. 15For a complete discussion, refer to chapter 6 of Survival Models and Their 

Estimation (London 1988, second edition). 16A participant who dies during the interval does so at age ; a 

participant observed to withdraw from the study during the interval also does 

so at age less than .

The scheduled exit age (ZI) is the age at which the participant

is scheduled to exit the study as an observed ender on December 31, 2000. The actual exit age at death (THI) or withdrawal

(PSI) is the exact age at which the participant exits the study

under those particular decrements.

The fractional-time variables used to determine scheduled

exposure contributions for an observation interval are defined

below:

• Time at which observation begins: 

• Time at which observation is scheduled to end: 

The amount of exposure contributed at each duration is summarized as follows:

As previously mentioned, exact exposure is used in calculating

recovery probabilities. This type of exposure is only credited to

the interval during which conversion to old-age benefits takes

place. Using a fractional-time variable, exact exposure is

defined as , where is determined as follows:

Note that in this context PSI represents the exact age at the

time of switch to old-age benefits.

F. Duration and Graduation

The intervals for which a participant is under observation—

measured in years since selection—are called durations. For

each select age and duration , the ordered pair represents the amount of exposure contributed to the observation

interval . For durations extending 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 method18. 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), while deviating as little as possible from the original estimates.

G. Survival Tables

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

first calculated for select age , using a radix of

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

the table and older attained ages. Functions for select ages

 are then derived retrospectively from the ultimate values. For example, is determined from using the survival probabilities of the select period for the given select age.

The number represents the number alive at the beginning of duration from those originally entitled at select age

. Note that the number alive at various select ages are not

actual counts of disability beneficiaries. Rather, the number

living at the beginning of any duration are for illustrative purposes, chosen to represent the probability of survival based on

values shown in tables 7A-7C.

Survival tables 15A-15B are similarly constructed from selectand-ultimate recovery probabilities shown in tables 14A-14B.

Since recovery is no longer considered after attaining normal

retirement age, these tables are truncated after attained age 64.

Note that in this case, “survival” refers to beneficiaries who

remain on the DI rolls by not recovering.

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. Numbers for

the following example can be found in table 8A. Of the male

beneficiaries disabled at select age 30, the following table

shows the number surviving (that is, still on the disability rolls)

after the stated number of years:

H. Expected Future Lifetime

Future lifetime tables are produced from the survival functions

described above using basic actuarial principles found in any

standard actuarial text on life contingencies. Also presented in

this study are the results of aggregating over duration, by select

age (see tables 11, 18, and 25) or attained age (see tables 12,

19, and 26).

Aggregate lifetime for a specific select age is an exposureweighted average of the expected future lifetime at each duration of that age. This differs from aggregate lifetime for a specific attained age, which is an exposure-weighted average of

the expected future lifetime of those durations representing a

particular attained age.

For example, aggregate lifetime for select age 40 is a weighted

average of the expected lifetimes shown for each duration 0

through 34—where each duration represents a different

attained age. In contrast, aggregate lifetime for attained age 40

is the average of the expected lifetimes for a select 40-year-old

at duration 0, select 39-year-old at duration 1,... select 20-yearold at duration 20—all of whom are attained age 40.

I. Probabilities and Absolute Rates

The data for this study were collected in a multiple-decrement

environment, however, we present results for only two major

decrements—death and recovery. The symbol represents

the probability of death in the presence of the other decrements. Mathematically, this is represented by:

 = 

where is the probability of surviving under all decrements;

and is the force of mortality.

For each of the causes of decrement in a multiple-decrement

model, it is possible to define a single-decrement model that

depends only on a particular cause of decrement. The symbol

 represents the single-decrement (absolute) rate of death.

Mathematically, this is represented by:

= 

where is the probability of not dying. In this representation, observation stops at the point of non-death decrement,

and scheduled exposure is replaced by the smaller quantity of

exact exposure. The result is lower exposure totals relative to

those used in formulating death probabilities.

For each combination of select age and duration, the multipledecrement probabilities and are calculated by dividing the observed number of deaths or recoveries by the exposure for that cell. These probabilities are used to derive the

absolute rates of decrement and as shown below

(note that d, r, and superscripts refer to death, recovery, and

total decrement, respectively):

Derive the total decrement probability:

Under the assumption of constant force for each decrement

over the age interval , absolute rates may be derived

using the following:

In this study, absolute rates are presented on a “per thousand”

basis.
