Conducted every ten years, the Census is the largest survey in the United States. The 2010 Census represented the most massive participation movement ever witnessed in the US, with approximately 74% of households returning their census by mail. The Census Bureau hired about 635,000 employees to walk through neighborhoods throughout the United States to count the remaining households.
The 100% characteristics form was used with every person and housing unit in the United States. It includes information on sex, age, and race by geographic location. Census data is available at many geographic levels, including blocks, zip codes, county, and state.
The 2010 Census asked detailed questions that include information on educational attainment, marital status, labor-force status, and income. The Census is a very large database and hence has many uses ranging from racial profiling in police-stop baselines to wage data.
