Since 1980, the growth in the median household size-adjusted income of Americans with a disability has fallen below that of the rest of the working population overall and in the vast majority of states. Knowledge of state-specific trends in the relative household income rate of people with disabilities compared to the rest of the working population can be of assistance to state and federal policy makers and disability advocates. Such information can help track comparisons over time to assess the impact of policy and economic interventions to address such disparities. A recent report from the Cornell University Rehabilitation Research and Training Center (RRTC) for Economic Research on Employment Policy for Persons with Disabilities uses data from the March Current Population Survey (CPS) to estimate median household size-adjusted income for persons with and without a disability in the non-institutionalized working-age (aged 25 through 61) civilian population in the United States, and for each state and the District of Columbia for the years 1980 through 1998. The median household size-adjusted income of persons with a disability relative to those of persons without a disability are found to vary greatly across states. (The relative median household size-adjusted income is the median household size-adjusted income of those with disabilities as a percentage of the median household size-adjusted income of those without disabilities. The larger this number is, the closer are the median household size-adjusted incomes of those with and without disabilities.)
