FAQ

Where does the data come from?

Only official statistics published by the police, interior ministry or national statistics office of each country (see Sources). We estimate nothing ourselves and use no press reports or crowd-sourced indices.

What does the score out of 100 mean?

100.0 means recorded-crime rates per inhabitant among the lowest in the country, 0.0 among the highest. Score = 100 − weighted mean of national percentile ranks (0 to 100, one decimal). Before 31 Oct 2026 the score ran from 1.0 to 10.0: new = (old − 1) / 9 × 100.

Can I compare two countries?

No. Definitions and recording rules differ: each score is a ranking within the country (or state).

Is it real time?

No. These are official annual statistics, updated when the producers publish.

Why is an area grey?

Because the official figure is not published at that level of detail, or not at all.

Why do tourist or shopping areas score badly?

Offences are divided by residents, not visitors, so busy centres are penalised.

Do you use origin or nationality?

No. No data on origin, nationality, religion or immigration is used.

Can I reuse the data?

Yes, see Download the data: CSV files for countries whose licence allows it, with the source attribution to keep.
