Counties with the highest leukemia death rates in Iowa

Among 22 Iowa counties with published values, the counties with the highest leukemia death rates are Boone County, IA (10, 1.75 times the U.S. rate of 5.7), Winneshiek County, IA (9.5, 1.67 times the U.S. rate of 5.7) and Cerro Gordo County, IA (9.2, 1.61 times the U.S. rate of 5.7). Values are per 100,000, age-adjusted. 3 of the 22 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.
