Housing Units, Population and Cost Rank Measures for Idaho

Here we explore the evolution and dynamics of the housing supply in Idaho, the relative cost of Idaho housing, the housing mix and the change in Idaho population. Housing supply here is defined as the number of housing units (i.e: houses, condos, apartments etc..). For this analysis, the Idaho population number we're most interested in is the 18 and over population since the under 18 population typically isn't a buyer or renter in the housing market. All data on this page comes from the Census ACS 1 year survey. Jump to Idaho sections: housing units, housing cost, housing mix, population.
