I have a map of a county precincts, all 195. The attribute table shows the FID number, the Precinct number, a few columns such as district and shape, and most importantly it shows the number of Dems, Reps, and Unaffiliated voters.
I'm looking at making chloropleth maps which reflect the political party of the people in the precinct. It's easy enough to map the number of Dems or Reps, but I'm curious how to use the percent of total function. I'd like to show Dems are for ex: 50% of a precinct. However, I think the Normalization tab is also tabulating the area, some of the district numbers, and other irrelevant information for this task.
My question is...how would I go about using just the columns with the political parties as a percent of total?
Many thanks in advance.
