Characteristics of Noninstitutionalized DI, SSI, and OASI Program Participants, 2016 Update
Research and Statistics Note No. 2022-01 (released April 2022)
by Matt Messel and Brad Trenkamp

The authors use data from the March 2017 Annual Social and Economic Supplement of the Current Population Survey matched to Social Security administrative records to produce tables providing detailed information on the economic and demographic characteristics of Disability Insurance beneficiaries and Supplemental Security Income recipients in calendar year 2016. The tables update those published in a 2015 Research and Statistics Note that used 2013 data from the Survey of Income and Program Participation (SIPP), a 2014 Research and Statistics Note that used 2010 SIPP data, and a 2008 Research and Statistics Note that used 2002 SIPP data. For this note, the authors add tables showing selected characteristics of Old-Age and Survivors Insurance beneficiaries.

Improving the Measurement of Retirement Income of the Aged Population
ORES Working Paper No. 116 (released January 2021)
by Irena Dushi and Brad Trenkamp

Research has shown that survey-reported pension and retirement income measures may suffer from reporting errors, which lead to biased estimates of income and poverty of the aged population. In this paper, the authors evaluate income estimates from the Census Bureau's 2016 Current Population Survey (CPS) Annual Social and Economic Supplement (ASEC). The authors compare 2016 CPS ASEC public-use data with public-use survey data from the 2016 Health and Retirement Study and with CPS ASEC data that have been merged with administrative data from the Internal Revenue Service (IRS) and the Social Security Administration. They find that for the population aged 65 or older, supplementing the CPS ASEC with IRS and Social Security administrative data results in a higher estimate of pension income's share of aggregate income, less estimated reliance on Social Security, and a lower estimated rate of poverty. They also find that the HRS provides better estimates of the income of the aged population than the public-use CPS data.

The Importance of Social Security Benefits to the Income of the Aged Population
from Social Security Bulletin, Vol. 77, No. 2 (released May 2017)
by Irena Dushi, Howard M. Iams, and Brad Trenkamp

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.

When Impairments Cause a Change in Occupation
from Social Security Bulletin, Vol. 75, No. 4 (released November 2015)
by Alexander Strand and Brad Trenkamp

This study examines workers who had physical or mental impairments that prevented continued work in their pre-onset occupation but did not qualify for Disability Insurance (DI) benefits. More specifically, we examine workers who experienced the onset of such impairments, applied for DI once, were denied benefits on the basis of residual ability to work in other occupations, and did not appeal the decision. In contrast to allowed claimants, this group of individuals continued to participate in the labor market at comparatively high rates. We describe their post-onset labor market experience, including employment rates and earnings losses by type of impairment.

The Food Stamp Program and Supplemental Security Income
from Social Security Bulletin, Vol. 67, No. 4 (released May 2008)
by Brad Trenkamp and Michael Wiseman

The Food Stamp Program (FSP) and Supplemental Security Income (SSI) are important parts of national public assistance policy, and there is considerable overlap in the populations that the programs serve. This article investigates FSP participation by households that include SSI recipients and assesses the importance of various provisions of the Food Stamp Program that favor SSI recipients.
