What color sequences were used for the maps?
Color schemes were chosen based upon the number of data classes, the types of data being mapped (e.g., number of adults versus percent of adults), consideration of the display devices to be used for the resulting maps, and the need to avoid colors that cannot be differentiated by individuals with impaired color-vision.4 The color schemes for the maps were selected by referring to ColorBrewer (http://www.colorbrewer.org*), an online tool for selecting color schemes.
