Montana: Total housing units
The 2012-2016 data come from the U.S. Census Bureau's American Community Survey. They are based on averages of data collected in 2012, 2013, 2014, 2015, and 2016. 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 American Factfinder provides 3-year estimates for counties with at 20,000 people, and 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.
In Montana . . .
- the total number of housing units was 482,825 in 2010;
- the number of housing units increased by 10.0 percent from 1980 to 1990; increased by 14.3 percent from 1990 to 2000; and increased by 17.0 percent from 2000 to 2010;
- in 2012-2016, 56.4 percent of all housing units were owner occupied, 27.5 percent were occupied by renters, and 16.0 percent were vacant.
NOTE: These ACS data are estimates based on a five-year average, meaning that data gathered from 2012, 2013, 2014, 2015, and 2016 are averaged together to come up with the results shown here. There is no problem with comparing these data to census data from 2000.
