U.S. / county disease rankings

Counties with the highest childhood cancer incidence rates (U.S.)

Among 583 U.S. counties with published values, the counties with the highest childhood cancer incidence rates are Manassas city, VA (33.6, 2.05 times the U.S. rate of 16.4), Jefferson County, WI (33.3, 2.03 times the U.S. rate of 16.4) and Lonoke County, AR (30.3, 1.85 times the U.S. rate of 16.4). Values are per 100,000, age-adjusted. 45 of the 583 are significantly above the U.S. rate.

Source: NCI and CDC State Cancer Profiles, both sexes, all ages. These are county-level figures, age-adjusted as published by the source, compared with the U.S. rate. A high rate does not prove an environmental cause: age, smoking, income, access to care, screening and chance all move county rates, and small counties swing widely. Significant means the lower bound of the county’s 95 percent confidence interval is above the U.S. rate.
