The document discusses data from surveys and statistics in several European countries regarding crimes committed by migrants versus native populations. The key findings are: 1) In many Western European countries, the belief that migrants increase crime is not supported by new sociological surveys, as crime rates have decreased despite increased migration. 2) The rate of criminal acts between natives and migrants with residence permits is almost overlapping in these countries. 3) Legalizing migrant status decreases their likelihood of committing crimes. 4) Differences in immigration laws across Europe make it difficult to draw definitive conclusions about the relationship between migration and crime rates.
