When Every Dollar Counts: Comparing Reported Earnings of Social Security Disability Program Beneficiaries in Survey and Administrative Records

This article examines differences between survey- and administrative data–based estimates of employment and earnings for a sample of Social Security Administration (SSA) disability program beneficiaries. The analysis uses linked records from SSA’s National Beneficiary Survey and administrative data from the agency’s Master Earnings File. The authors find that estimated employment rates and earnings levels based on administrative data are higher than those based on survey data for beneficiaries overall and by sociodemographic subgroup. In proportional terms, the differences between survey and administrative data tend to be greater among subgroups with survey-reported employment rates that are lower than that of beneficiaries overall.
