Do you have a source for that statistic?

The Independent does have a story that claims that
“more Somali Swedes dying in Sweden than any other group. In Stockholm, one of the hardest-hit areas has been Jarva, where around 90 per cent of the population comes from an immigrant background”
but the embedded hyperlink leads to a secure page

and the Frontiere basically parrots the Independent or vice versa
