The study is in two major parts. First, on the basis of a study of the factorial social ecology of Stockholm in 1980, the city is grouped into major urban environments, and thereafter the criminality in these different urban environments is studied cross sectionally for 1982. Second, the trends in crime in the city of Stockholm and its different types of urban environments are studied over a 20-year period (1968-1987). The findings show significant decreases between types of urban environments in rates of crimes, offenders and victims, crime structure, and crime and distance. Also, the trends in crime were significantly different between types of urban environments. 11 tables, appendix, and 23 references. See NCJ 124605-124612 for individual papers. (Author abstract)
