Abstract:
|
This paper examines the reliability of SIPP-based estimates of participation in the Social Security and Supplemental Security Income (SSI) programs. Using data from the 1996 SIPP panel matched to administrative data from the Social Security Administration, we examine how individuals' program participation status and benefits amounts---as reported in the SIPP---differ from their administrative records. We find a high frequency of inconsistencies between SIPP and administrative data, but many are small in terms of dollar amount. Imputation in the SIPP explains many, but not all, of the inconsistencies. We examine how the frequency and type of inconsistencies vary by age and income. The findings have important implications for efforts to use SIPP to measure poverty and simulate eligibility for programs such as the Food Stamp Program.
