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.
