Trends in Elective Deferrals of Earnings from 1990–2001 in Social Security Administrative Data

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.

Measuring the Relative Importance of Social Security Benefits to the Elderly

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 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 Administrations 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.

Characteristics of Noninstitutionalized DI and SSI Program Participants

Benefit Adequacy in State Workers' Compensation Programs

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.

Poverty-level Annuitization Requirements in Social Security Proposals Incorporating Personal Retirement Accounts

In the current discussions of Social Security reform, voluntary personal retirement accounts have been proposed. Recent research and debate have focused on several aspects of these accounts, including how such accounts would affect aggregate saving, system finances, and benefit levels. Little attention, however, has been paid to policies that would govern the distribution of account balances. This analysis considers such policies with respect to the annuitization of account balances at retirement using the Social Security Administration's Modeling Income in the New Term (MINT) model and a modified version of a recent legislative proposal to evaluate the effects of partial annuitization requirements.

Social Security Benefit Reporting in the Survey of Income and Program Participation and in Social Security Administrative Records

The quality of Social Security benefit reporting in household surveys is important for policy research on the Social Security program and, more generally, for research on the economic well-being of the aged and disabled populations. This is particularly true for the aged among whom receipt of Social Security benefits is nearly universal and reliance on such benefits is considerable. This paper examines the consistency between Social Security benefit amounts for May 1990 as reported in the Survey of Income and Program Participation and given in the Social Security Administration's administrative records for the respondent.

The Social Security Administration's Death Master File: The Completeness of Death Reporting at Older Ages

To provide a more detailed assessment of the coverage of deaths of older adults in the Social Security Administration's Death Master File (DMF), this research note compares age-specific death counts from 1960 to 1997 in the DMF with official counts tabulated by the National Center for Health Statistics, the most authoritative source of death information for the U.S. population. Results suggest that for most years since 1973, 93 percent to 96 percent of deaths of individuals aged 65 or older were included in the DMF.

Attrition in the New Beneficiary Survey and Followup, and Its Correlates

In this article we explore the extent of and reasons for attrition in the New Beneficiary Survey (NBS) between the first interview in 1982 and the followup interview in 1991. We examine a variety of potential determinants of attrition, separating the probability of attrition due to death from a refusal to be interviewed. Because the NBS sample is drawn from and linked to Social Security administrative records, information on mortality as a cause of attrition is exact. Hence, we are able to examine differences in the patterns and predictors of attrition due to these two causes of attrition and differences between attrition among retired and disabled workers.

Who Is "62 Enough"? Identifying Respondents Eligible for Social Security Early Retirement Benefits in the Health and Retirement Study

Workers are not instantly eligible for Social Security retirement benefits on their 62nd birthdays, nor can they receive benefits in the month they turn 62. This note discusses how well researchers can do using data from the Health and Retirement Study (HRS) to identify respondents old enough to receive and report early Social Security retirement benefits. It shows that only some workers aged 62 at the time of an HRS interview will be "62 enough" to have received a Social Security benefit and reported it in the survey.

The Development of the Project NetWork Administrative Records Database for Policy Evaluation

This article describes the development of SSA's administrative records database for the Project NetWork return-to-work experiment targeting persons with disabilities. The article is part of a series of papers on the evaluation of the Project NetWork demonstration. In addition to 8,248 Project NetWork participants randomly assigned to receive case management services and a control group, the simulation identified 138,613 eligible nonparticipants in the demonstration areas. The output data files contain detailed monthly information on Supplemental Security Income (SSI) and Disability Insurance (DI) benefits, annual earnings, and a set of demographic and diagnostic variables. The data allow for the measurement of net outcomes and the analysis of factors affecting participation. The results suggest that it is feasible to simulate complex eligibility rules using administrative records, and create a clean and edited data file for a comprehensive and credible evaluation. The study shows that it is feasible to use administrative records data for selecting control or comparison groups in future demonstration evaluations.

Who Is "62 Enough": Identifying Eligibles for Social Security Early Retirement in the Health and Retirement Study

Either the normal retirement age (NRA) or the earliest eligibility age (EEA) for Social Security retirement benefits would be increased under many proposals for Social Security reform. As a consequence, research interest in who retires at early ages and the potential effects of an increase in the NRA or EEA has grown. This note discusses how well researchers can do using data from the Health and Retirement Study in identifying the pool of respondents who could have received early Social Security retirement benefits.

Linkages With Data From Social Security Administrative Records in the Health and Retirement Study

The Health and Retirement Study (HRS is a major longitudinal study designed for scientific and policy researchers for study of the economics, health, and demography of retirement and aging. This note describes the data from SSA records that have been released for linking to HRS data, linkage rates resulting from the consent process, and subgroup patterns in linkage rates.

Linkages with Data from Social Security Administrative Records in the Health and Retirement Study ^*

The Health and Retirement Study (HRS) is a major longitudinal study designed for scientific and policy researchers for study of the economics, health, and demography of retirement and aging. The primary HRS sponsor is the National Institute of Aging, and the project is being conducted by the Survey Research Center of the Institute for Social Research at the University of Michigan. Several agencies, including the Social Security Administration, are supporting the project. This is the second paper describing SSA's data support for the HRS. It describes the data from SSA records that have been released for linking to HRS data, linkage rates resulting from the consent process, and subgroup patterns in linkage rates.

The Accuracy of Survey-Reported Marital Status: Evidence from Survey Records Matched to Social Security Records

Many researchers have concluded that, in surveys, divorced persons often fail to report accurate marital information. In this paper, I revisit this issue using a new source of data—surveys exactly matched to Social Security data. I find that divorced persons frequently misreport their marital status, but there is evidence that the misreporting is unintentional. A discussion of possible improvements in surveys is presented. Implications for the study of differential mortality and the study of poverty among aged women are discussed.

Two Papers on a New SIPP-Based Microsimulation Model of SSI and OASDI

This working paper includes two interrelated papers presented at the annual meeting of the American Statistical Association in August 1991. The papers outline the central ideas and the progress to date associated with the development of a new microsimulation model for program analysis at the Social Security Administration (SSA). The first paper, Rationale for a SIPP-Based Microsimulation Model of SSI and OASDI, relates the analytical potential of the proposed model to data development efforts intended to overcome specific information gaps. It also suggests areas in which the model can enrich SSA's abilitiy to address issues specifically related to either the Supplemental Security Income or Old-Age, Survivors, and Disability Insurance programs or issues requiring comparative analysis of both programs. The second paper, Implementing an SSI Model Using the Survey of Income and Program Participation, describes progress on a preliminary version of the model focusing on the SSI program. It includes a brief description of the model, presentation and discussion of initial results, and comparisons with other studies.

Reflections on the Income Estimates from the Initial Panel of the Survey of Income and Program Participation (SIPP) ^*

The Survey of Income and Program Participation (SIPP) represents a major effort on the part of the Federal statistical community to improve the quality and comprehensiveness of information on the economic resources of the household sector and to permit a more accurate portrayal of the impact of government tax and transfer programs on the economic status of the population.

This paper will not offer a comprehensive and definitive statement on the quality of SIPP income data. Neither the time nor resources available to the author, nor indeed, the state of SIPP data products, would permit making such a statement. However, enough information is available to offer a tentative interpretation of important aspects of the income data available from the first SIPP panel. Two broad themes will be touched upon. Since it is generally believed that the major technical defect of income surveys is the substantial tendency to underidentify the sources and amounts of income received by the population, the issue of the completeness of the SIPP money income estimates will be the central issue. A second important aspect of income data has to do with its suitability for analytic purposes.

Adjusted Estimates of the Size Distribution of Family Money Income for 1972

It is well-known that for most purposes income size distribution data collected in household surveys are far from ideal. The problems with those data can be separated into two types: the data items that are collected, and the accuracy of the data collected. Usually, although there are important exceptions, the income data collected are confined to cash income before taxes, thus ignoring the effects of both taxes and noncash income of all types. Also, the income estimates usually are for one year, which often is not the best accounting period for analysis. Furthermore, there usually is a lack of adequate detail by income type, and the data ordinarily are not sufficiently detailed to adjust for changes in the composition of the family unit during the income accounting period.

An Example of the Use of Statistical Matching in the Estimation and Analysis of the Size Distribution of Income

This paper discusses the use of statistical matching in the estimation and analysis of the size distribution of family unit personal income. Statistical matching is a relatively new technique that has been used to combine, at the single observation level, data from two different samples, each of which contains some data items that are absent from the other file. In a statistical match, the information brought together from the different files ordinarily is not for the same person but for similar persons; the match is made on the basis of similar characteristics. In contrast, in an "exact" match, information for the same person from two or more files is brought together using personal identifying information.
