Users may select to display a map of the continental U.S. or an individual state. This option is provided to focus attention on one specific state during animation. The data and Color-Groups are the same for a state, whether it is shown individually or as part of the entire United States. Alaska and Hawaii are not included in this atlas because the spatial data smoothing method employed is more reliable on contiguous areas.
Cancer sites are based on the SEER Causes of Death
For most cancer sites, options for sex include Both Sexes, Males, and Females. For some cancer sites only one option is available.
Red/yellow/blue is a diverging color ramp which highlights the high rates in red and the low rates in blue.
A monochromatic color ramp is available with each sex getting a different color ramp (orange-both sexes, purple-females, males-green).
This monochromatic color ramp is better for black and white printing than the red/yellow/blue color ramp.
Each sex has its own color to reinforce the fact that the cutpoints for each sex can be different as they are based only on data from that sex.
