2000 Census

American Community Survey - 1 year - 2010

The American Community Survey (ACS) is an ongoing statistical survey that is annually conducted by the United States Census Bureau.  The survey gathers information previously contained only in the long form of the decennial census.  The ACS data are estimates (not counts) of population and housing characteristics collected throughout the year.

In order to help communities, state governments, and federal programs, the ACS gathers information such as age; sex; race; family and relationships; income and benefits; health insurance; education; veteran status; disabilities; where you work and how you get there; and where you live and how much you pay for essentials.  The collected information is combined into statistics that are used by communities and agencies to plan investments and services.

The following reports are only a subset of the information available on the US Census Bureau's web page.
