County levels of lung cancer mortality were predicted by a decision tree model. All continental U.S. counties were segregated into seven statistically significant branches, characterized by local area poverty, estimated excess cancer deaths in ambient air, and earlier coronary heart disease death rates. Smoking prevalence is a branching determinant for all counties and poverty is a determinant for 5 of the 7 county groupings. The map illustrates the distribution of counties by county branches/groupings. More information about this analysis is found in:
