Length of stay on the Supplemental Security Income Disability Program.

This article analyzes duration on the Supplemental Security Income (SSI) disability rolls prior to age 65 among children and working-age adults, based on a 10-year followup of 1974-82 cohorts of new awardees by utilizing monthly data from administrative records for 1974-92, and on statistical projections beyond the followup period. Although SSI means testing is responsible for a high proportion of early suspensions, when multiple spells are accounted for, long stays dominate. The estimated mean length of all first SSI spells is 5.5 years. It is 11.3 years for disabled children, 1.3 years for disabled adults eligible for both the Social Security Administration's Disability Insurance (DI) and SSI, and 6.4 years for adults eligible for SSI only. When multiple spells are accounted for, the projected mean total preretirement-age SSI disability stay almost doubles to 10.5 years for all awardees and increases to 26.7 years for children.
