Incidence rates are per 100,000 person-years from 1992–2004 and are derived from the Surveillance, Epidemiology, and End Results (SEER) Program (www.seer.cancer.gov) SEER*Stat Database: Incidence - SEER 13 Regs Limited-Use, Nov 2006 Sub (1992–2004) - Linked To County Attributes - Total U.S., 1969–2004 Counties, National Cancer Institute, DCCPS, Surveillance Research Program, Cancer Statistics Branch, released April 2007, based on the November 2006 submission.

Incidence rates are from 2000–2004 since these registries were not added to the SEER program until 2000.
