How long do child molesters serve in prison?

Those convicted of Criminal Sexual Conduct, or Sexual Assault against a Minor typically serve 8.7 years on average, the same as those who are convicted of rape (per DoJ statistics). Many states now have minimum sentence statutes now, so this statistic may be actually higher now. With the statute maximum of 20 years to life, it is not uncommon for offenders to serve half of the statutory maximum, or twice the minimum sentence. Although there are no hard, fast rules here.
