This document examines 8-year trends in the labor force status and other characteristics (including age and years of school completed) of persons with a work force disability, using March supplements to the U.S. Census Bureau's Current Population Survey (CPS). (Disabled persons are considered to be individuals 16 to 64 years old with a disability that prevents them from working or that limits the kind or amount of work they can do.) The CPS data are collected by interviewers who ask questions about each household member 14 years or older in every sample household. The number of housing units eligible for interviewing in the sample ranged from 65,500 in 1980 and 1981 to 57,000 in 1988. Among the findings are the following: (1) the poor were more likely to be disabled workers compared to those with a more comfortable income level; (2) Blacks were more likely to have a work disability than Whites or Hispanics; (3) the incidence of work disabilities is significantly higher among males 55 to 64 than among males 25 to 34, among people who have less than an eighth-grade education than among high school or college graduates, and among persons who live in poverty; (4) disabled males were unemployed at a rate of 14 percent over the 1983 to 1988 period, and men without disabilities were unemployed at a 6 percent rate; and (5) in 1988, 14 percent of women with disabilities were unemployed, compared to 5 percent of women who were not disabled; and (6) the unemployment rate for men with and without disabilities peaked in 1983. The document contains detailed data tables and copies of the questionnaire. (CML)
