The total number of automobiles, vans, and light trucks--one ton or less--available at home for the use of members of the household, ascertained for occupied housing units. This tabulation adds together responses to the two separate questions on automobiles and trucks or vans. "Three or more" vehicles available is the highest category of this question. The statistics do not reflect the number of vehicles privately owned or the number of households owning vehicles. These items were asked on a sample basis.
