This is a statistical map which depicts the percentage of change in residents of each state from the 1990 census to the 2000 census. Each shade of green represents a different amount of change which makes it easy to interpret general trends in regions of the country though it is not as helpful for more specific analyzation of data. The information from this map comes from the US Census Bureau and the map can be found at http://www.census.gov/population/cen2000/map02.gif
