Peeping Tom, Voyeurism has high prevalence rates in most studied populations. Voyeurism was initially believed to only be present in a small portion of the population. This perception changed when Alfred Kinsey discovered that 30% of men prefer coitus with the lights on. This behaviour is not considered voyeurism by today's diagnostic standards, but there was little differentiation between normal and pathological behaviour at the time. Subsequent research showed that 65% of men had engaged in peeping, which suggests that this behaviour is widely spread throughout the population. Congruent with this, research found voyeurism to be the most common sexual law-breaking behaviour in both clinical and general populations. In the same study it was found that 42% of college males who had never been convicted of a crime had watched others in sexual situations. An earlier study indicates that 54% of men have voyeuristic fantasies, and that 42% have tried voyeurism. In a national study of Sweden it was found that 7.7% of the population (both men and women) had engaged in voyeurism at some point. It is also believed that voyeurism occurs up to 150 times more frequently than police reports indicate. This same study also indicates that there are high levels of co-occurrence between voyeurism and exhibitionism, finding that 63% of voyeurs also report exhibitionist behaviour.
