Counties with the highest leukemia incidence rates in South Dakota

Among 13 South Dakota counties with published values, the counties with the highest leukemia incidence rates are Lincoln County, SD (21.5, 1.48 times the U.S. rate of 14.5), Beadle County, SD (21.2, 1.46 times the U.S. rate of 14.5) and Union County, SD (19.4, 1.34 times the U.S. rate of 14.5). Values are per 100,000, age-adjusted. 2 of the 13 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.
