Auto ownership and automobile use are common indicators that determine transportation choice and travel behavior. Households with no automobiles tend to have individuals that have high levels of walking for utilitarian transportation. Auto ownership is one component used to determine automobile costs, along with vehicle miles traveled (VMT), which comprises an important determinant of transportation costs. This measure provides the modeled number of automobiles per household.
The data for the auto ownership measure is derived from the Consumer Expenditure Survey (CES) released by the U.S. Bureau of Labor Statistics. The automobile ownership measure is the average number of vehicles per household.
- Auto ownership = number of vehicles per household for regional median family income.
This indicator was calculated by the U.S. Department of Housing & Urban Development (U.S. HUD), and U.S. Department of Transportation (U.S. DOT) using data from the sources listed below.
