Official statistics show men commit more crime than women, sociologists disagree on the reasons why. Some sociologists argue female offending rates go unnoticed/punished because the criminal justice system treats women more leniently, through ideas such as the chivalry thesis (Pollak). However, some sociologists believe the gender differences in offending is because of the way women are socialised meaning they have less opportunity or desire to commit crime. On the other hand, other sociologists argue women do commit crime, but men commit more due to the idea of ‘masculinity’.
