+Indicator Methodology
To calculate the percentage of mobile-home housing units, the American Community Survey (ACS) (https://www.census.gov/data/developers/data-sets/acs-5year.html ) 5-year estimates are used to first determine the total number of mobile homes in each county. This total is then divided by the overall number of housing units in the same area, as provided by the ACS. The resulting fraction is multiplied by 100 to convert it to a percentage.
