Maps of age-adjusted breast cancer mortality rates and the risk computed using alternative estimators. The fill color in each county represents the age-adjusted mortality rate per 100,000 person-years recorded over the period 1970–1994 (top graph) or the risk estimated using the following approaches: population-weighted average, global and local empirical Bayes smoothers, and Poisson kriging. The color legend applies to all the maps; the class boundaries correspond to the deciles of the histogram of original rates.
