Notes on Rankings
These data are based on perceptions of visitors, expats, and local residents.
Your perception may be different from that listed, especially if you come from a place that is substantially different from the city or country you are visiting. For example, if you come from a very safe and orderly city, your perception of a city with moderate crime may be that it is crime ridden. Whereas, if you come from a war-torn country your perception of a city with moderate crime may be that it is very safe.
