In the fall of 2011, the Census Bureau released data from the American Community Survey (ACS) one-year (2010) and three-year (2008-2010) estimates for the United States. This third edition of The Who, What, and Where of America is the first to include data on unmarried partner households, health insurance coverage, and median real estate tax. It uses the ACS data to present a concise resource of information that tells a story about America-its population, levels of education, types of employment and housing, and patterns of migration and transportation in one, convenient volume.
