Module 6: Data Classification

This week's map presents the percentage of the population over the age of 65 in Escambia County, Florida, divided up into U.S. Census Bureau tracts. Data in each inset map is distributed using a different method, Quantile, Natural Breaks, Equal Interval and Standard Deviation. Standard deviation distribution seems to be the least appropriate for this map, as it does not show the actual percentages, but instead shows the variation above and below the average.

This map was created in ArcMap, each data distribution shown in a separate data frame. Data distribution was done through the Symbology tab in the data properties, using ArcMap default for each classification method.
