A housing unit is a house, an apartment, a mobile home, a group of rooms, or a single room that is occupied (or if vacant, is intended for occupancy) as separate living quarters. Separate living quarters are those in which the occupants live and eat separately from any other persons in the building and which have direct access from the outside of the building or through a common hall.
A housing unit is owner-occupied if the owner or co-owner lives in the unit, even if it is mortaged or not fully paid for.
The homeownership rate is computed by dividing the number of owner-occupied housing units by the number of occupied housing units or households.
Scope and Methodology:
These data are collected in the American Community Survey (ACS). The data are estimates and are subject to sampling variability. The data for each geographic area are presented together with margins of error at factfinder2.census.gov. The data are period estimates, that is, they represent the characteristics of the housing over a specific 60-month data collection period.
