From NARSOL, here is a handy compilation of facts and statistics about sex offender registries complete with supporting links.
Check it out at the NARSOL website.
The palm card is a collection of the most salient facts regarding sexual offending, quickly available for reference or for distribution. Since space is at a premium, citation references are omitted with one citation being given that will point here.
Also, from the Florida Action Committee, check out a Sex Offense Registry Fact Sheet compiled by Dr. Emily Horowitz, a professor with the Dept. of Sociology and Criminal Justice at St. Francis College.
