Growth in Disability Benefits [PDF ebook] 

This collection of original papers reveals why caseloads of the nation’s two largest income entitlement programs for disability-Social Security Disability Income (SSDI) and Supplemental Security Income (SSI)-have soared. Using the Social Security Administration data, the authors identify factors that contribute to the programs‘ growth including program design, changing demographics, the labor market, and the interaction with other programs in the nation’s social safety net.
