Sources and method
Every figure on Car Statistics comes from official open data. We use only free, openly licensed sources available via API or download, and never paid, login-gated or personal data. Each page also states its specific source and the year of the data.

Method
We ingest each source on a schedule, store it, and render comparable pages. Numbers are rounded for readability. Derived figures (for example the share of cars older than 10 years, or average fleet age) are computed from the underlying Eurostat age bands. Pages without enough unique data are kept out of search results.
