How to Size an Automotive Market Using Registration Data

5 min read · Updated 5 October 2026

Step by step

Define the market. Pick the segment (for example two-wheelers), the geography and the period. Decide whether electric and used imports are in or out.
Pull registrations. Get monthly registrations by make, model and CC for the geography. Registrations are the most direct measure of demand.
Group into bands. Group models into engine-capacity or price bands that match your product range, so you compare like with like.
Remove noise. Look at a full year or more to smooth seasonality, and flag one-offs such as fleet orders.
Calculate share. Divide your registrations, or a competitor's, by the total in the band to get share by band, model and region.
Cross-check with trade flows. Compare with export and import data to see whether supply is building up or running short.
Test the trend. Compare the last twelve months with the twelve before, band by band, to see which are growing.

Mixing bands, such as treating a 110 cc commuter and a 350 cc cruiser as one market.
Using national totals when demand is local.
Reading one strong month as a trend.
Ignoring import and export flows in markets that depend on imports.
