I know, by reputation the Balkan Region doesn't look good, but when you look at the data it paints a totally different picture. My hunch is that a lot of petty thieves types have moved into Western Europe as the business is more lucrative there.
numbeo is a measurement of perceptions of crime, not actual crime rates. Looking at Stockholm vs. Jeddah (Saudi Arabia), Stockholm comes off the worse for safely walking at night.
