The paper empirically analyses the causal relationship between immigrants and crime using data for German administrative districts between 2008 and 2019. Before the refugee crisis (2008-2014), an increase in the current share of immigrants increased the total crime rate. In contrast, the effect was negative (or insignificant) during and after the refugee crisis (2015-2019). When analysing the total period, the estimates average out to zero. Studying more closely the composition of the migrant group, a plausible explanation of the negative (or insignificant) effect of immigrants on crime in the later period is related to a larger share of migrants with a less certain residence status.
