GIS3015 Week 3

The maps below were created from data collected during the 2000 census. They show the population of black Escambia County residents by census tract. The first map shows the percentage of residents using 4 different classification methods. The second map is only depicting the Natural Breaks method which I believe to be the most accurate method for this example. Unlike the Equal Interval and Quantile methods, Natural breaks take into account how that data are distributed along the number line. Because of that, Natural breaks minimize differences of data values in the same class. This allows each data class to be better represented on the map.

 (I added a border in Arcmaps, I'm not sure why it isn't showing up on the blog)
