This report uses data from the National Health Interview Survey (n=1,792 million) to describe trends in labor force participation among persons with disabilities for the period 1983 through 1994. It examines labor force participation among persons with disabilities compared to participation among persons without disabilities, how people with disabilities associated with major categories of chronic conditions fare in the labor market, and how age and gender affect employment of persons with disabilities. Results found that during this period, men without disabilities experienced a relative decline in labor force participation by a rate of 0.6 percent, while those with disabilities experienced a 4.1 percent decline. While women without disabilities experienced a 9.7 percent increase in labor force participation, women with disabilities experienced a 21.7 percent increase, although from a lower base. By 1994, the labor force participation rates of younger men and women with disabilities (ages 18-44) were more than 20 percentage points lower than those of typical peers. The labor force participation rates of persons with disabilities differed dramatically across condition. Persons with disabilities caused by impairments and respiratory conditions had high labor force participation rates, while those with disabilities caused by mental, endocrine, and circulatory conditions had low rates.
