Counties with the highest leukemia incidence rates in Washington

Among 30 Washington counties with published values, the counties with the highest leukemia incidence rates are Skagit County, WA (19.5, 1.34 times the U.S. rate of 14.5), Grays Harbor County, WA (19, 1.31 times the U.S. rate of 14.5) and Douglas County, WA (18.3, 1.26 times the U.S. rate of 14.5). Values are per 100,000, age-adjusted. 8 of the 30 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.
