The impact of refugees on socioeconomic outcomes in destination countries, including crime, can be significant. This column finds that the increase in the refugee population in Turkey led to an increase in the incidence of crime of between 2% and 4.75% per year, correspondsing to about 75,000-150,000 additional crimes per year. These results highlight the need to strengthen the social safety systems, take actions to counter the impact on the labour market, and provide support to the criminal justice system to mitigate the repercussions of massive refugee inflows.
