Crime and reactions to crime in 34 Swedish birth cohorts: from historical descriptions to forecasting the future

This article analyses 34 Swedish birth cohorts with regard to their participation in crime as measured by data from the convictions database maintained by Statistics Sweden. Most existing cohort studies are limited to one or a few cohorts. By contrast, the present study includes 34 cohorts, i.e. all persons born in Sweden between 1958 and 1991. The article discusses methodological problems associated with this type of approach and examines the possibility of making forecasts. The central results are that the number of males with a criminal record has decreased, whereas the number of females has remained fairly stable. Forecasts indicate that the cohorts' participation in crime will continue to decrease. Research and policy implications of the findings are outlined. It is proposed to introduce cohort statistics as a standard branch within regular criminal justice statistics.
