Electric Vehicles

Results

There were 2 electric vehicles in the sample of 316 vehicles. Based on this lower number of electric vehicles in the sample than expected, we think it best to extrapolate the registration data itself using a constant function to form our estimate for March 2025.

Figure 1: Values for the first three dates are calculated by dividing the number of all-electric vehicle registrations by the total number of registrations at the given date cutoff. The value for the last date is a constant extrapolation.

Caveat: No attempts are made to account for the fact that the government registration records are not a complete census of the target population. The estimate that 2.31% of vehicles in the target population are fully electric is only a rough guess.
