Census 2010 was taken using only of a 'short form', consisting of basic questions about age, sex, race, Hispanic origin, household relationship, and owner/renter status. The American Community Survey (ACS), a new Census Bureau survey, has been designed to replace the Decennial Census 'long form' beginning in 2010 and to provide demographic, housing, social, and economic data every year for the U.S., states, and local areas. ACS data for all geographical areas down to Block Group are now available.
Information is current as of May 2011.
