The above maps were produced for the week 6 choropleth lab. They show the percentage change in population for the U.S. by state and census divisions for 1990-2000. I decided to round the numbers for each class. I thought this would be easier for a map user to read. I was not pleased with my Hawaii scale bar. I deleted part of it before I scaled the state thinking it would look better than a big bar. I then figured out how to scale down the numbers and bars without disturbing the length of the bars. If I could go back I would change that. I found the easiest way to change the states to grayscale was to calculate my classes first, then create the legend. Once I had the colors for the legend, I just clicked on each stated and hit the appropriate legend color with the eyedropper tool. The hardest part of the lab was dividing the data in excel. I found the best way was to give each state a division code then sort that way, as someone suggested in the discussions. I think this step had the most potential for human error. I had to double check this and indeed had to correct some errors.
