The U.S. Census Bureau (www.census.gov) provides multiple web sites that offer statistics in a variety of forms. One of the most useful sites for prevention professionals and others is the American Factfinder web site, which is a link from the U.S. Census Bureau web site.
This is one site where information at the local level can be obtained, down to the Block, which is smaller than the Block Group. For example, one can learn the Congressional and Legislative districts numbers. Tables and profiles available for any given Block Group from this site include a profile of the general demographic characteristics; general housing characteristics; tenure, household size, and age of householder. Reference maps are also available.
