Light-Duty Vehicle Population in California
Light-Duty vehicle population is updated annually in April to reflect the number of vehicles “on the road” during the selected calendar year. Light-Duty zero-emission vehicle (ZEV) population is lower than new ZEV sales because of vehicle retirements, accidents, owners moving out of state, or other reasons.

Data Collection Information
- Frequency of Historic Data Collection
Year. Prior to 2018, the DMV provided the CEC with database snapshots twice a year, in April and October. Starting In 2018, the DMV began providing quarterly database snapshots allowing CEC staff to align the sales and population counts with the calendar year. However, transitioning to calendar year causes a discontinuity in the counts from 2016 to 2017, where 2017 includes registrations from October 2016 through the end of December 2017.
Additionally, registrations of new vehicles may take up to three weeks to be processed by DMV. Thus, vehicles purchased at the end of a reporting period may not be reflected until the subsequent snapshot. This is corrected for at year-end for both population and sales by updating the January database with the April database to capture vehicles that registered at the end of the previous year. Vehicles whose registration is either current or less than 35 days expired are counted in Vehicle Population.
