These 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.
Housing types include single family homes, structures with two housing units (like duplexes), multiple units per structure (three or more units, such as apartment buildings), mobile homes and other housing types.
According to the Census Bureau, mobile homes include both occupied and vacant mobile homes to which no permanent rooms have been added, but do not include those used only for business purposes or for extra sleeping space, or those for sale on a dealer's lot, at the factory, or in storage. The other housing types category includes any living quarters occupied as a housing unit that does not fit the other categories. Examples include boats, RVs, vans, houseboats, railroad cars, etc.
