The 1970, 1980, 1990, and 2000 Equal Employment Tabulations were sourced from the decennial censuses for those years. The EEO Tabulation 2006-2010 (5-year ACS data) was sourced from the American Community Survey. Listed below are the one survey and one decennial census that provide Census Bureau’s statistics on the Equal Employment Opportunity Tabulation. Following a general description of each program are specifics related to this topic.

The American Community Survey (ACS) is an annual, nationwide survey of more than 3.5 million households in the U.S. The ACS is part of the Decennial Census Program and replaces the long form, which the Census Bureau last used during Census 2000. The survey produces statistics on demographic, social, economic, and other characteristics about our nation's population and housing. We release ACS 1-year estimates in September for the pervious calendar year and 5-year estimates in December for the previous five calendar years.

The decennial census counts every resident in the U.S. once every ten years, in years ending in zero. The Constitution of the United States mandates the head count to make sure each state can fairly represent its population in the U.S. House of Representatives. States use the numbers to draw their legislative districts. The federal government uses them to distribute funds and assistance to states and localities.
