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.
