This chart summarizes sex offender registration statutes in the U.S. as codified in each jurisdiction as of August 2018.

Where noted, this chart also relies upon the following additional resources: (1) information provided by law enforcement agencies in each jurisdiction, as frequently-asked questions (FAQs) and summary pages; (2) information gleaned from conversations with registration officials in each jurisdiction; and (3) information obtained by Shawn M. Rolfe, M.A., during telephonic surveys of registration officials in 2015 and published in When a Sex Offender Comes to Visit:  A National Assessment of Travel Restrictions, Criminal Justice Policy Review 1 (Nov. 2017).
