Why do the map colors and map categories look different on state maps than on the national map?
The state maps show quintiles based on the distribution of death rates in all counties within the state, whereas the national map shows quintiles based on the distribution of death rates in all counties in the country. These maps look different because there are large differences in county death rates from state to state and region to region. The national map shows the national disease patterns for each racial or ethnic group and is the source for seeing how the counties in a state compare with the counties in the rest of the country. Each state map shows the distribution of counties with high, medium, and low rates based only on the range of death rates within that state.
