Decreasing number of young licence holders and reduced number of accidents. A description of trends in Sweden.

The following study compares rates of licence holders and rates of car accidents in two age cohorts born in Sweden in 1972 and 1977, respectively. The research material consists of all accidents with injury which these young people have been involved in as car drivers at age 16–21. The periods concerned are 1988–1993 and 1993–1998, respectively. In the respective periods altogether 2082 and 1453 car accidents leading to injury were recorded. The results show a lower rate of licence holders and a lower rate of car accidents in the later age cohort. Particularly the rate of fatal accidents and accidents leading to serious injury was lower. Comparing the earlier with the later age cohort, the reduction of accidents was greatest in the most densely built-up counties of Sweden and in the groups with the highest risk, namely those age and socio-economic groups who had the highest rate of fatalities and accidents leading to serious injury. Factors behind the decrease in the rates of licence holders and the rates of car accidents are discussed. Recession in the economy and less interest in car driving among young people are factors which are suggested as explanations.
