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). Utah data is drawn from the Utah Department of Health IBIS-PH.

The data only includes statistics 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 in 2009 according to the Nationwide Inpatient Sample was 55%. This differs slightly from the overall average reported by the 2009 National Hospital Discharge Survey which puts the rate at 56.2%, and the 2009 Kids' Inpatient Database that reports 55.9% (all reflecting a slow downward trend from a high of about 85% in 1965).
