Nationwide survey designed to provide communities with a fresh look at how they are changing. 2005 is the first full year. Prior years were small test runs. Replaces the decennial long form. Tells us what the population looks like and how it lives. Includes occupancy status, homeownership data, and housing cost data. IPUMS also contains the data in an easier to use format. More recent data may be found directly on the Census website. For summary statistics, use Social Explorer.
