Number of publicly owned vehicles in the District of Columbia

* Vehicles of the civilian branches of the Federal government are given in this table. Vehicles of the military services are not included. Distribution by state is estimated by the Federal Highway Administration.
** The information, compiled chiefly from reports of state authorities, is incomplete in many cases. Some states give state-owned vehicles only; others exclude from registration certain classes, such as fire apparatus and police vehicles. For the states not reporting state, county, and municipal vehicles separately from private and commercial vehicles and those reporting unsegregated totals only, classification by vehicle type has been approximated on the basis of other available data or estimated.
