Additional demographic information formerly collected through the Census long form, such as income, educational attainment, marital status, etc. is now gathered by the American Community Survey (ACS) , a multi-year sampling program.
ACS demographics are not included in 2010 Census tables, although ACS data is in data.census.gov. For example: if you search for a 2010 Census file containing income data, you will get no results.
The Decennial Census: shows the number of people who live in the U.S.
The American Community Survey: shows how people live.
