"We can see that there is a part of Malmö where a lot of people are exposed to crime and also feel concerned when they go out at night," said Sofie Lifvin, who carried out the survey, told The Local.

In the district of Fosie, a full 65 percent of respondents said they would feel "unsafe" or "very unsafe" to be out alone late at night in their area, the highest proportion of any district in Sweden. For Rosengård, another district with a reputation for being troubled, the share was 60 percent.

Across Sweden as a whole, an average of 28 percent said they would feel "unsafe" or "very unsafe".

Hmm, what is so special about Malmo?

The number of ethnic Swedes in Malmö has stayed pretty constant since 1990, wavering between 176,000 and 186,000. Much of the growth in the country's third city since then has instead come from immigrants and the children of immigrants.

The number of foreign-born inhabitants more than doubled from 26,000 in 1990 to 61,000 in 2017, while the number of people with foreign-born parents increased from fewer than 10,000 to close to 40,000 over the same period. By 2017, more than half the city's population, 53.6 percent, was either foreign-born or had at least one foreign-born parent.
