NOTE: The US Census's American Community Survey numbers are estimates based on sample data collected from January 1, 2005 to December 31, 2009. The data are estimates, not counts, unlike the US Census, whose numbers are released every 10 years. Because they are estimates, the data has margins of error, which generally are larger with smaller communities or groups.
