Safetlas

Methodology & sources

Safetlas shows officially recorded crime - data published by national police forces and statistics offices. No scraped news, no user guesses, no vibes.

The rules we follow

  1. Rates, not raw counts. Everything is crimes per 1,000 residents, so a big city and a small town are comparable.
  2. Compare within one country only. Countries define and record crime differently; colours and rankings never cross borders. The only cross-country layer is survey-based perception (Numbeo) and the Georgetown WPS women's safety index, clearly labelled.
  3. Grey never means unsafe. It means no reliable official data.
  4. Tourist-area caveat. Per-resident rates inflate in places with many visitors and few residents (city centres, ports, station districts). We say so wherever it applies.
