Methodology

Each row compares inspections from the same age band, in the same country.

The country index rescales the model's defect rate so that 100 equals the country average for that band.

Two models are only compared if they share at least two age bands.

What counts as a failed inspection differs per country; never compare a figure on this page with a figure from another country.
