Due to differences in definitions, data sources and criminal justice procedures, comparing homicides between countries is not without problems. To overcome these limitations, we have constructed a joint European Homicide Monitor (EHM). So far, Finland, the Netherlands and Sweden constitute the basis of the database. In this contribution, we give an overview of this new data set. In doing so, we elaborate on methodological issues that arose when constructing this data set and discuss the feasibility of constructing an international and comparable homicide data set. Preliminary results show that the EHM as a joint database provides unique opportunities to closely monitor homicide across Europe.
