Electric Vehicle Population Size History

This shows the number of electric vehicles that were registered by Washington State Department of Licensing (DOL) each month. DOL integrates National Highway Traffic Safety Administration (NHTSA) data and the Environmental Protection Agency (EPA) fuel efficiency ratings with DOL titling and registration data to create this information.

{"sql": "
    SELECT *
    FROM \"wa-gov/electric-vehicle-population-size-history-d886-d5q2\".\"electric_vehicle_population_size_history\"
