Various factors have contributed to the increase in the number of reported crimes in the post-war period. The main reason is an improved standard of living that has increased the availability of goods that are attractive to thieves combined with a reduced social control between people. This has created increased opportunities for crime. But other things that might have affected the level of reported crime in the statistics are variations in people's tendency to report crime and changes in statistics procedures.
Also very common are various sorts of vandalism, which amount to 12 percent of the number of reported crimes. Crime against individuals — particularly violent crime — accounts for 18 percent of the total number of reported crimes. Crimes against individuals include things such as assault and sex offences. Crimes against the Road Traffic Offences Act (trafikbrottslagen) have increased and now stand for just over 6 percent of the total number of reported crimes. Approximately 8 percent of the total number of reported crimes consists of fraud and about 6 percent are crimes against the Narcotic Drugs Act (narkotikastrafflagen).
