This article provides an overview of the Understanding America Study (UAS), a nationally representative Internet panel of approximately 6,000 adult respondents that is administered by the University of Southern California. The UAS, which began in 2014, represents one of the richest sources of panel data available in the United States. It includes over 50 survey modules on topics such as retirement planning, economic well-being, and psychological constructs. This article reviews the UAS methodology; describes how external researchers may commission UAS surveys, incorporate their own survey questions and methodological experiments, and conduct randomized controlled trials; highlights selected publicly available data from UAS surveys on cognition, personality, financial literacy and behaviors, political views, and other topics; and discusses opportunities for external parties to work with UAS administrators in developing new surveys and future lines of research.
Poverty Among the Aged Population: The Role of Out-of-Pocket Medical Expenditures and Annuitized Assets in Supplemental Poverty Measure Estimates
The Supplemental Poverty Measure (SPM) does not account for the aged population's ability to draw from asset principal to cover living expenses. In this article, the authors ask two questions: (1) How much can we conservatively expect the aged to withdraw from their assets annually, and (2) To what extent would the inclusion of such assets alter the estimated proportion of the aged in SPM poverty—specifically, the proportion of the aged who are “pushed” into SPM poverty because of their medical out-of-pocket expenditures?
Using Survey of Income and Program Participation data linked to Social Security administrative files, the authors examine the preapplication employment patterns of Social Security Disability Insurance (DI) applicants for periods of varying lengths up to 24 months before application. The employment histories of about half of the applicants are characterized by stable employment in well-paying jobs; most policy proposals related to workforce retention or DI diversion target this type of worker. The other half of the applicants have either intermittent or no work experience in the preapplication period. Proposals that focus on DI applicants with recent or long-term attachments to the workforce are therefore likely to miss this other half of eventual DI applicants. Future policy proposals should consider outreach to people who lack a strong labor force attachment and who might need a broader array of supports to remain in or return to the workforce.
Social Security benefits are the most important source of U.S. retirement income. Over time, however, trends in employer-provided pension offerings, societal changes, and Social Security program rule changes have altered the distribution of income by source among the aged population. In this article, the authors examine the reliance on Social Security benefits of people aged 65 or older using data from the Current Population Survey, the Survey of Income and Program Participation, and the Health and Retirement Study.
A number of studies have used estimates of historical and projected lifetime net transfers (benefits less taxes) by birth cohort under the Old-Age and Survivors Insurance program to calculate and compare the aggregate present-value sum of such transfers for selected birth-cohort groups. Those calculations indicate that, from a program accounting perspective, the earliest generations of program participants received large transfers from later generations of participants. Some recent studies have referred to this cumulative transfer to the earliest generations as a “legacy debt” and characterized it as a burden borne by the later generations. This article clarifies the legacy debt concept and discusses the conditions required for a legacy debt to exist in a meaningful economic sense.
The Supplemental Poverty Measure (SPM) and Children: How and Why the SPM and Official Poverty Estimates Differ
In 2011, the Census Bureau released its first report on the Supplemental Poverty Measure (SPM). The SPM addresses many criticisms of the official poverty measure, and its intent is to provide an improved statistical picture of poverty. This article examines the extent of poverty identified by the two measures. The authors present a detailed examination of poverty among children (aged 0–17). For a more comprehensive view of poverty and comparison purposes, some findings are presented for two older segments of the U.S. population.
The Supplemental Poverty Measure (SPM) and Nonaged Adults: How and Why the SPM and Official Poverty Estimates Differ
In 2011, the Census Bureau released its first report on the Supplemental Poverty Measure (SPM). The SPM addresses many criticisms of the official poverty measure, and its intent is to provide an improved statistical picture of poverty. This article examines the extent of poverty identified by the two measures. The authors present a detailed examination of poverty among nonaged adults (those aged 18–64). For a more comprehensive view of poverty and comparison purposes, some findings are presented for younger and older segments of the population.
Longitudinal Patterns of Disability Program Participation and Mortality Across Childhood SSI Award Cohorts
This article follows six annual cohorts of childhood Supplemental Security Income (SSI) disability awardees between 1980 and 2000, for a time horizon up to 30 years after initial SSI award, in many cases well into adulthood. The authors compare trajectories of successive awardee cohorts as the SSI program evolves from 1980 to recent years. The results show that the proportion of awardees in SSI-only status declines over the life cycle, with over half transitioning to other statuses roughly after 10 to 15 years. Many awardees transition from the SSI program to concurrent or Disability Insurance–only benefit status, and increasing proportions of awardees are deceased or off the rolls and alive. These patterns are common for all awardee cohorts, but there are major changes in trajectories across cohorts. Compared with the early cohorts, the more recent cohorts display sharper declines in mortality and steeper increases in the proportion off the disability rolls for other reasons. These two trends have opposite effects on the duration of disability program participation over the life cycle, with important policy implications.
The Supplemental Poverty Measure (SPM) and the Aged: How and Why the SPM and Official Poverty Estimates Differ
In November 2011, the Census Bureau released its first report on the Supplemental Poverty Measure. The SPM addresses many criticisms of the official poverty measure and is intended to provide an improved statistical picture of poverty. This article examines the extent of poverty identified by the two measures. First, we look at how the SPM and official estimates differ for various aged and nonaged groups. Then, we look at why the SPM poverty rate for the aged is much higher than the official rate.
We find that three factors—(1) population growth, (2) the growth in the proportion of women insured for disability, and (3) the movement of the large baby boom generation into disability-prone ages—explain 90 percent of the growth in new disabled-worker entitlements over the 36-year subperiod (1972–2008). The remaining 10 percent is the part attributable to the disability “incidence rate.” Looking at the two subperiods (1972–1990 and 1990–2008), unadjusted measures appear to show faster growth in the incidence rate in the later period than in the earlier one. This apparent speedup disappears once we account for the changing demographic structure of the insured population. Although the adjusted growth in the incidence rate accounts for 17 percent of the growth in disability entitlements in the earlier subperiod, it accounts for only 6 percent of the growth in the more recent half. Demographic factors explain the remaining 94 percent of growth over the 1990–2008 period.
The deduction of Medicare premiums from Social Security benefit payments complicates the estimation of Social Security income in household surveys. Although the Census Bureau's Current Population Survey (CPS) and Survey of Income and Program Participation (SIPP) both aim to collect and record gross Social Security benefit income before Medicare premium deductions, comparing the survey data with Social Security records indicates that the CPS and SIPP estimates differ and suggests that some survey respondents may report net benefit income.
The income of the aged is composed largely of Social Security benefits, asset income, and pension income. Over the past three decades, the primary form of employer-sponsored pension has shifted from the traditional defined benefit plan to defined contribution plans, such as the 401(k). That trend creates problems for measuring the income of the aged because most household surveys of income either do not collect information about distributions from defined contribution retirement accounts or do not include those distributions in their summary measures of income. This article examines the impact of including distributions from retirement accounts on the estimated income of families headed by persons aged 65 or older.
This article discusses the importance of 401(k)-type defined contribution plans and individual retirement accounts in providing retirement income for current and future retirees. The rising prevalence and importance of this type of income creates measurement errors in the Current Population Survey and other sources of data on the income of the aged because those sources substantially underreport the distributions from such retirement plans.
Income typically falls in retirement, and the timing and extent of that decline concerns policymakers. If income from Social Security, pensions, and savings do not allow retirees to maintain their desired standard of living, they will face difficult and perhaps unexpected choices about reducing or eliminating certain kinds of expenditures. The income replacement ratio—retirement income expressed as a percentage of preretirement income—has become a familiar metric for assessing the adequacy of retirement income. This article presents the income replacement ratios experienced by members of the original sample cohort of the Health and Retirement Study (HRS), who were born between 1931 and 1941. Median replacement ratios among this sample fall as the retirement period grows longer.
Longitudinal Statistics on Work Activity and Use of Employment Supports for New Social Security Disability Insurance Beneficiaries
Longitudinal statistics on the employment activities of Social Security Disability Insurance beneficiaries offer a different perspective than the Social Security Administration's published statistics, which are based on annual data, and have important policy implications.
Defined Contribution Pension Participation and Contributions by Earnings Levels Using Administrative Data
This article examines the relationship between earnings levels and participation and contribution rates in defined contribution (DC) retirement plans. Specifically, the article estimates DC plan participation and contribution rates in 2006 both by the worker's current earnings and by the annual average of real earnings over the 10-year period 1997–2006. Using these two different measures of earnings allows us to assess whether employing a longer period of earnings, such as a decade, provides a better representation of pension outcomes than the short-term measure of current earnings.
The Impact of Response Error on Participation Rates and Contributions to Defined Contribution Pension Plans
The accuracy of information about coverage and contributions to defined contribution (DC) pension plans is important in understanding the economic well-being of future retirees because these plans are an increasingly important part of retirement income security. Using data from the 1996 and 2004 panels of the Survey of Income and Program Participation (SIPP) merged with information from W-2 tax records, we examine the extent to which estimated participation rates and contribution amounts to DC plans derived from SIPP reports differ from estimates obtained from tax-deferred contributions in the W-2 tax records.
Using the Social Security Administration's MINT (Modeling Income in the Near Term) model, this paper analyzes the progressivity of the Old-Age, Survivors and Disability Insurance (OASDI) program for current and future retirees. It uses a progressivity index that provides a summary measure of the distribution of taxes and benefits on a lifetime basis. Results indicate that OASDI lies roughly halfway between a flat replacement rate and a flat dollar benefit for current retirees. Projections suggest that progressivity will remain relatively similar for future retirees. In addition, the paper estimates the effects of several policy changes on progressivity for future retirees.
Researchers David Autor and Mark Duggan have hypothesized that the Social Security benefit formula using the average wage index, coupled with a widening distribution of income, has created an implicit rise in replacement rates for low-earner disability beneficiaries. This research attempts to confirm and quantify the replacement rate creep identified by Autor and Duggan using actual earnings histories of disability-insured workers over the period 1979–2004. The research finds that disability replacement rates are rising for many insured workers, although the effect may be somewhat smaller than that suggested by Autor and Duggan.
In a federal government career that lasted more than four decades, Mollie Orshansky worked for the Children's Bureau, the Department of Agriculture, the Social Security Administration, and other agencies. While working at the Social Security Administration during the 1960s, she developed the poverty thresholds that became the federal government's official statistical measure of poverty; her thresholds remain a major feature of the architecture of American social policy and are widely known internationally.
Replacement rates are common and useful tools used by individuals and policy analysts to plan for retirement and assess the sufficiency of Social Security benefits and overall retirement income. Because the calculation and meaning of replacement rates differs depending on the definition of preretirement earnings, this article examines four alternative measures: final preretirement earnings, constant income payable from the present value of lifetime earnings (PV payment), wage-indexed average of lifetime earnings, and inflation-adjusted average of lifetime earnings (CPI average). The article also calculates replacement rates for Social Security beneficiaries aged 64–66 in 2005.
It is widely known that about three-fourths of the working-age population is insured for Disability Insurance (DI), but the substantial role played by the Supplemental Security Income (SSI) program in providing disability benefit coverage is not well understood. Using data from the 1996 panel of the Survey of Income and Program Participation (SIPP) we find that over one-third (36 percent) of the working-age population is covered by SSI in the event of a severe disability. Three important implications follow: (1) SSI increases the overall coverage of the working-age population; (2) SSI enhances the bundle of cash benefits available to disabled individuals; and (3) interactions with other public programs—most notably the SSI path to Medicaid coverage—also enhance the safety net. Ignoring these implications could lead to inaccurate inferences in analytic studies.
Old-Age, Survivors, and Disability Insurance (OASDI, Social Security) benefits are indexed for inflation to protect beneficiaries from the loss of purchasing power implied by inflation. In the absence of such indexing, the purchasing power of Social Security benefits would be eroded as rising prices raised the cost of living. Recently, the Consumer Price Index used to calculate the Cost-of-Living-Adjustment (COLA) for OASDI benefits has come under increased scrutiny. Some argue that the current index does not accurately reflect the inflation experienced by seniors and that COLAs should be larger. Others argue that the measure of inflation underlying the COLA has technical limitations that cause it to overestimate changes in the cost of living and that COLAs should be smaller. This article discusses some of the issues involved with indexing Social Security benefits for inflation and examines the ramifications of potential changes to COLA calculations.
Benefit Adequacy Among Elderly Social Security Retired-Worker Beneficiaries and the SSI Federal Benefit Rate
The federal benefit rate (FBR) of the Supplemental Security Income program provides an inflation-indexed income guarantee for aged and disabled people with low assets. Some consider the FBR as an attractive measure of Social Security benefit adequacy. Others propose the FBR as an administratively simple, well-targeted minimum Social Security benefit. However, these claims have not been empirically tested. Using microdata from the Survey of Income and Program Participation, this article finds that the FBR is an imprecise measure of benefit adequacy; it incorrectly identifies as economically vulnerable many who are not poor, and disregards some who are poor. The reason for this is that the FBR-level benefit threshold of adequacy considers the Social Security benefit in isolation and ignores the family consumption unit. The FBR would provide an administratively simple but poorly targeted foundation for a minimum Social Security benefit. The empirical estimates quantify the substantial tradeoffs between administrative simplicity and target effectiveness.
Provided is a discussion of the cumulative effects of the measurement alternatives described in the three previous articles: considering family income of persons rather than aged units, using administrative data in place of survey reported data, and switching the data source from CPS to SIPP. The current-methodology CPS statistic of 17.9 percent of beneficiary aged units receiving all of their income from Social Security in 1996 falls to a substantially smaller estimated 4.5 percent of elderly beneficiary persons based on family income when using the SIPP and Social Security administrative data.
The Impact of the Unit of Observation on the Measurement of the Relative Importance of Social Security Benefits to the Elderly
Other publications using the same data source as Income of the Population 55 or Older, 2004 have produced different statistics for income and the relative importance of Social Security that appear contradictory. Depending on the unit of observation and whose income is considered, the estimates of the percentage of the elderly receiving all of their income from Social Security in 2004 varies from 13 percent to 22 percent. This article explains how the choice of the unit of observation impacts measures of the relative importance of Social Security benefits for the elderly.
The Impact of Survey Choice on Measuring the Relative Importance of Social Security Benefits to the Elderly
This article provides insight into how measures of elderly economic well-being are sensitive to the survey data source. In Social Security Administration's publication Income of the Population 55 or Older, data are based on the national Current Population Survey (CPS). The preciseness of the survey statistics depends upon the willingness and ability of CPS respondents to answer questions accurately. This article contrasts income statistics calculated using the CPS and the Survey of Income and Program Participation (SIPP). Administrative data for Social Security benefits and SSI are also used to evaluate the accuracy of the income estimates.
Estimates of Unreported Asset Income in the Survey of Consumer Finances and the Relative Importance of Social Security Benefits to the Elderly
Through the 1990s and the early 2000s, the Income of the Population 55 or Older has reported a decline in the proportion of the elderly receiving asset income and the corresponding rise in the proportion receiving all of their income from Social Security. This analysis uses the Survey of Consumer Finances from 1992 to 2001 to examine financial asset holdings of the elderly and to determine if those who do not report asset income in fact might hold assets that are likely to generate income. Imputing asset income from likely income-producing holdings, the article examines the impact of probable missing asset income information upon measures of elderly income.
New Evidence on Earnings and Benefit Claims Following Changes in the Retirement Earnings Test in 2000
In April 2000, Congress enacted the Senior Citizens Freedom to Work Act of 2000, which removed the retirement earnings test for individuals at the full retirement age and older. This paper examines the labor force activity of workers aged 65–69 relative to older and younger workers in response to the removal of the earnings test. We use the 1 percent sample of Social Security administrative data that covers the period from 4 years before to 4 years following the removal of the test. Quantile regression methods allow us to identify the earnings levels of workers who change their work effort.
During the first three decades of the Supplemental Security Income (SSI) program, the number of children receiving SSI because of a disability increased from 70,000 in 1974 to about 1 million at the end of 2005. With over 8,500 interviews completed between July 2001 and June 2002, the National Survey of SSI Children and Families (NSCF) is the first nationally representative survey since 1978 of noninstitutionalized children and young adults who were receiving SSI during the survey period or had formerly received SSI. The article discusses the objectives of the survey, its methodology and implementation, content of the questionnaire, a randomized response-incentive experiment, and related products including the release of a public-use data file.
This article summarizes several different methods used to measure the adequacy of wage replacement in state workers' compensation systems in the United States. Empirical research casts serious doubt on benefit adequacy, especially in the case of more serious disabilities.

This article reports research and analysis undertaken by a very successful collaborative, federal interagency work group on disability, convened by the Office of Management and Budget and charged with the development of a short set of disability questions for Census 2000. The process that culminated in the final disability questions on Census 2000 is described, along with a discussion of the complexities of defining and measuring disability.
This article examines poverty among persons aged 65 or older under experimental measures, which are based on a 1995 report released by the National Academy of Sciences. When compared with the official measure, the experimental measure produces higher poverty rates for all groups and narrower differences in poverty rates across groups.
The quest for suitable indices to summarize the inequality between two groups has lagged behind the effort to obtain summary coefficients of within-group inequality. Numerous measures of within-group inequality were proposed, and their merits and shortcomings debated. Yet, apparently, at the same time, there was little exploration of alternative indices to the ratio-of-medians and ratio-of-means for measuring differences between groups.
A long-term disability reflects the interaction between a continued physical or mental impairment that limits functioning and restrictions and requirements of the social environment. Impairments and functional limitations are, however, central to any disability, and the Social Security Administration is constructing measures to assess the impact these factors have on the development of disability.
In particular, SSA is interested in work disability or loss of or reduction in the ability to work. The functional capacity index presented in this paper was developed for that purpose. Based on a model prevalent in the literature, the index is an attempt to represent the underlying medically related aspects of disability in contrast to other factors such as the person's age, educational level, or work history.
