We are excited to announce the release of 3-year Social, Economic, and Housing Comparison Profiles. This first release of 3-year Comparison Profiles will give a side-by-side comparison of 2010-2012 ACS 3-year and 2007-2009 ACS 3-year estimates. The profiles also contain the statistical significance column that indicates if the estimates are statistically different (at the 90% confidence level). Access the 2010-2012 3-year Comparison Profiles on American FactFinder.
