Exercise 7

Choropleth Map

Description:

This choropleth map depicts the percentage of people per Wisconsin County who have identified themselves on the U.S. census as “Native American & Alaska Natives”. I classified the data by using the buckets portion of the “fill color polygons” section of the feature styles. I gave it 5 classes. The classification method I used for this was custom. Since it was a small range of percentages, I didn’t want to do any of the classifications because they all made much of the map the lightest color since the majority was .1-.2 percent. I customized it so that the classes would be more evenly weighted. The pattern I found in the results of the merged choropleth map (which was not a surprise at all) is that the highest percentage of Native American population correlates with the counties where federally recognized tribes reside (shown in figure 2 below). Specifically, the highest percentage being Menominee county. Another pattern is that the .2 to .5 class is mostly surrounding the higher classes. You can insinuate from that Native Americans, if not living on the reservations, live in counties with closer proximity to the reservations. A higher percentage also reside in the northern half of the state, which makes sense since most of the tribe land is in the northern half.
