Minority Population



The Minority Population in Idaho map was constructed using US Census Bureau information from the year 2000. The census data is contained within a shapefile of Idaho counties. Since the minority population is composed of multiple ethnicities, the pie chart is an ideal method to display the variability in the data. Two trends become apparent using the pie chart mapping. The first is that the dominant ethnicity in Idaho is Hispanic. The next is that the southern part of the state has a greater total minority than the northern panhandle. The other category in the pie chart raises some interesting questions. The obvious is: what dos other mean in regards to ethnicity? The other one is: why does Idaho have a significant population of this other category? The main limitation to the pie chart method is that it is a little confusing. It is a bit of a challenge to match up the pies with the counties they are meant to represent. However, it is a nice way to look at a variety of related attributes to discern some patterns.
