U.S. hospitals and practitioners are not legally required to report how many circumcisions they perform, so the state circumcision statistics on the map below are drawn from government surveys. They were compiled by Hugh O'Donnell using the State Inpatient Databases (SID), Nationwide Inpatient Sample (NIS), and Kids' Inpatient Database (KID), all of which are published by the U.S. Department of Health & Human Services Healthcare Cost and Utilization Project (HCUP).

HCUP only includes data for boys who are born in hospitals and circumcised before discharge, though, so boys who are circumcised later are not counted. This means that the actual infant circumcision rates may be considerably higher than the rates shown below.

The overall average U.S. hospital infant circumcision rate reported by the National Hospital Discharge Survey as of 2007 (the latest year for which data is available) is 55.4%, reflecting a slow downward trend from a high of about 85% in 1965.
