U.S. Census Fact Sheets Census Fact Sheets provide the same information included in the American Community Survey (ACS) DATA Profiles. However, all of the fact Sheets are based on the ACS 2005-2009 five year estimates, regardless of population. If you are looking for profiles for communities or counties with populations greater than 20,000 consider the ACS DATA Profiles where you can develop a profile based on three average estimates (pop. > 20,000) and one-year estimates for geographies with populations 65,000+.
