Immigration and cultural diversity help to reduce crime rates
The US has experienced a 45% drop in violent crime rates since 1990. During the same period, the number of unauthorised migrants climbed from 3.5 to 11 million, and the percentage of the population who were foreign born rose from 8 to 13%. Correlation, of course, is not causation. But it is a good indication that more migration does not translate into more crime. And in fact, researchers from the US have similarly concluded that ‘broad reductions in violent crime during recent years are partially attributable to increases in immigration’. In the UK, immigrant “enclaves” – defined as neighbourhoods where at least 30% of the residents are immigrants – have lower levels of crime and victimisation than similar socio-economic areas without a large immigrant presence.
