A substantial portion of the rise in Social Security Disability Insurance rolls since 1984 has been attributed to the Social Security Disability Benefits Reform Act. Using data from the National Health Interview Survey, this paper examines who the Act effectively targeted. The analysis shows that new enrollees were demonstrably taller than previous enrollees, suggesting that the Act expanded eligibility to individuals in better health and socioeconomic circumstances However, the estimated effect of increased SSDI eligibility on employment is low, suggesting that the Act targeted males who would have otherwise been unemployed.
