Tokyo scored highly across all categories. The report highlights its low crime rate, and how city planners improved quality of life by banning diesel cars to reduce pollution, and pedestrianising large parts of the centre.

Before you start packing your bags, however, the conclusions aren’t simple: Tokyo also happens to be considered the world’s riskiest city, in part because of the huge number of people who would be harmed in an inevitable future earthquake. Nor does the report actually say which city is safest for you. From an individual’s point of view, as opposed to the municipal officials responsible for the smooth running of a city, isn’t personal safety more important than the threat of cyber crime? In that case, maybe you should look at Singapore instead. And what if health security is your priority, but you’ll take your chances on the streets? Move to Zurich: first for health, 13th for personal safety.
