The most recent work dedicated to presenting actuarial experience of the Social Security Disability Insurance (DI) program is Actuarial Study #118,
Social Security Disabiity Insurance Program Worker Experience (June 2005). The study examined historical data with regard to disability incidence and benefit termination through calendar year 2004. A comprehensive analysis of termination activity of the DI rolls was also presented based on 100 percent worker data collected for the 5-year period 1996-2000. The overall content of Actuarial Study #122, and the methods used to prepare those results are consistent with those of the prior study; namely, disability incidence and benefit termination is examined through calendar year 2009, and a comprehensive analysis of termination activity is presented for the 5‑year period 2001-05. Details of the underlying methodology for table construction are outlined in the appendix.
This study does not present projections of actuarial cost estimates for the DI program. For this information, the reader is referred to Actuarial Study #121,
Short-Range Actuarial Projections of the Old‑Age, Survivors, and Disability Insurance Program, which was developed to provide a detailed description of the methodology and assumptions used in projecting the costs associated with the entire OASDI program.
The study is also available on the Social Security Administration’s website at www.socialsecurity.gov/OACT/pubs.html. Additional copies of the study are available upon request.
