Dutch quantitative criminologists have been active in most fields of the discipline of criminology: research has been done on the etiology of crime and, in relation to this, the self- report methodology. A number of victimization surveys have been implemented, and in relation to this, attention was given to fear of crime, victims in the judicial system, and situational approaches to crime. There has been research on policy evaluation, sentencing, and differential treatment in the criminal justice system, as well as alternative sanctions. Recently, three major international studies have been coordinated by Dutch criminologists: an international self-report study, an international victim survey of households, and an international survey of victimization among businesses. This paper describes the first two studies and briefly compares some of their features. Overall, it is apparent that Dutch quantitative criminology is embedded in the international mainstream of criminology and generally has been strongly related to policy concerns. 3 figures and 106 references
