>Vienna comes top again this year, though maybe for the last time because of violent migrant gangs making some areas in central Vienna too dangerous for natives or tourists. So Zurich (currently 2nd) may move up to first next year. There's 5 German cities in the top 20 plus Stockholm that are said to have similar issues, so there may be a bigger shake-up next year.

The effect of fugitives is more marked in smaller communities - the % of other ethnic groups there was sometimes near zero and therefore the increase is more drastic if seen/measured as rise. And Merkel has realized that she made at least a political mistake in the sense of hurting potential voter wishes.
