The ACS replaced the decennial census long form in 2010 and now collects long-form-type information on a continuing basis rather than every 10 years, providing more current data. The ACS provides a regular stream of updated information for states and local areas and has revolutionized the way we use data to understand our communities. It produces social, housing, and economic characteristics for demographic groups. 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.
