The Effect of Easy Availability of Pornography on the Incidence of Sex Crimes: The Danish Experience

The Danish liberalization of legal prosecution and of laws concerning pornography and the ensuing high availability of such materials present a unique opportunity of testing hypotheses concerning the relationship between pornography and sex offenses. It is shown that concurrently with the increasing availability of pornography there was a significant decrease in the number of sex offenses registered by the police in Copenhagen. On the basis of various investigations, including a survey of public attitudes and studies of the police, it was established that at least in one type of offense (child molestation) the decrease represents a real reduction in the number of offenses committed. Various factors suggest that the availability of pornography was the direct cause of this decrease.
