Figure 15

Maps of breast cancer mortality rates simulated under three scenarios for the underlying risk map. The number of cases for each county was simulated by random sampling of a Poisson distribution that is defined by the risk and population value derived from the three risk maps of Figure 14 and the white female population map of Figure 1. The units are age-adjusted mortality rates per 100,000 person-years. The color legend applies to all the maps; the class boundaries correspond to the deciles of the histogram of original rates.
