Perceived safety in Tjörn

93% of residents in Tjörn feel safe outdoors after dark (Kolada citizen survey, 2025). The figure covers the whole municipality and complements the ranking, which is based on reported crime.

How we measure safety

The safety index is based on reported crime per DeSO area (2024–2025 average), measured against how many people actually spend time there: residents, one third of the daytime population and an estimate of visitors based on the number of nearby restaurants and bars. This gives city centres and nightlife areas, where many people spend time but few live, a fairer figure. The index measures reported crime — not how safe people feel, and not the police assessment of vulnerable areas.
