The 2014-2018 data come from the U.S. Census Bureau's American Community Survey. They are based on averages of data collected in 2014, 2015, 2016, 2017, and 2018. These estimates cannot be used to say what is going on in any particular year in the period, only what the average value is over the full period. The Census Bureau's data.census.gov also provides 1-year estimates for counties with at least 65,000 people. We use 5-year estimates because they are available for all counties and allow comparison to other counties within the region.
The Census Bureau defines a housing unit as a house, an apartment, a mobile home or trailer, a group of rooms, or a single room occupied as separate living quarters (or if vacant, intended as separate living quarters). Housing units are classified as being occupied – either by owners or renters – or vacant.
