Week 6: Chloropleth Maps (part 2)


Attached is a grayscale map of the 1990 to 2000 population change data by U.S. state. This map is prepared using Equal Value classification. Using Excel, I grouped and calculated division-specific population changes in this time interval.

Percent Population Change by Division

Northeast Region
New England Division: 5.42%
Middle Atlantic Division: 5.50%
Midwest Region
East North Central Division: 7.49%
West North Central Division: 8.94%
South Region
South Atlantic Division: 18.83%
East South Central Division: 12.77%
West South Central Division: 17.76%
West Region
Mountain Division: 33.04%
Pacific Division: 15.07%
