Rachel Giese considers a possible connection between increased immigration and decreased crime.
In Canada, an overall drop in crime has paralleled the upsurge in non-European immigration since Pierre Trudeau championed multiculturalism in the 1970s. Half of Toronto’s population now consists of those born outside Canada; notably, the city’s crime rate has dropped by 50 percent since 1991, and is significantly lower than that of the country as a whole. Could it be that immigrants are making us all safer?
… Statistics Canada has now released findings from a spatial analysis of crime data in Canadian cities that suggest the percentage of recent immigrants in various regions of Toronto and Montreal is inversely proportional to all types of violent crime; in the latter case, it concluded that while various socio-economic factors increase crime, “the proportion of recent immigrants lowers the violent crime rate; it acts as a protective factor.”
