In 2022, seven states and the District of Columbia had more than 10 PEV registrations per thousand people. California led the nation in plug-in vehicle (PEV) registrations with 27.55 per thousand people. The next highest state was Hawaii with 15.43 PEV registrations per thousand people. More than half of the states had over five, while no state had fewer than one PEV registration per thousand people. Higher PEV registrations per thousand people trended along the West Coast and the Northeast with some exceptions, such as Colorado, which was one of the top states.
Note: PEVs refer to plug-in electric vehicles, which include both all-electric vehicles and plug-in hybrid vehicles.
