Is there a study I can read for this?
To stay on-topic and on-source: "[Gang violence] is concentrated in highly segregated immigrant neighbourhoods. In Husby, a suburb of Stockholm, more than 80% of the population are migrants or the children of migrants, most of them from Iraq, Somalia, Syria and Turkey." https://www.economist.com/europe/2020/11/28/why-sweden-strug... Do you have a counter-factual source showing that immigrants are not more violent in…
Gang violence is not the only form of violence. Are there really no forms of violence which are concentrated in highly segregated ethnic Swedish neighborhoods?
And there are non-violent crimes.
Another question is, are the numbers of immigrants who do not live in highly segregated immigrant neighborhoods with gang violence? It looks like over 1 million people in Sweden were born outside of Europe, or 10% of the population. They can't all be involved in violent crimes.
The Wikipedia entry for Husby points out the crime rates increased 'after the closure of the closest police station to Husby, in Rinkeby, in 2014. The station was reopened on the first of September 2023.' The Economist article you linked to was written in 2020.
Which leads me to wonder if immigrant neighborhoods were under-protected, which would place at least some blame on government failure rather than the people living there.
