The Census Bureau collects data on disability primarily through the American Community Survey (ACS) and the Survey of Income and Program Participation (SIPP). The definitions of disability are not always alike so caution should be taken when making comparisons across surveys. Generally, the SIPP estimates of disability prevalence are broader and encompass a greater number of activities on which disability status is assessed. The ACS has a more narrow definition but is capable of producing estimates for states, counties, and metropolitan areas. Because the ACS has replaced the decennial long-form as the source for small area statistics, there is no disability data in the 2010 Census.
In addition to these recent data sources, the Census Bureau has also produced disability estimates from the 2000 Census, and the Current Population Survey Annual Social and Economic Supplement (CPS ASEC). Other Federal agencies also collect and report disability statistics. Depending on your needs, one survey may be more suitable than another.
