Ancestry in Western Suffolk

Data from the Census Bureau's 2008-2010 American Community Survey on how residents identified their ancestry when given a selection of choices. Some towns are not listed because the number of residents surveyed was too small. Also, because this information is based on surveys, there is a different margin of error for each statistic. A complete listing of those margins and of all the data from Long Island, including information from 45 communities with populations of 20,000 or more, is available on this PDF.
