Deserting Central USA

From 2000-2010 the population of the central United States declined. A combination of a higher death rate than birth rate and outward migration led to a fall in the population of counties running down the nation’s midsection.

You can view the population trend in every county in the USA from 2000 to 2010 on the Population Change Estimates 2000 - 2010 interactive map. When you run the choropleth animation on this map you will quickly notice the blue band emerging down the center of the country as the populations fall in counties throughout this central area of the country.

This animated population change map is actually one of 64 example maps available on GitHub which demonstrate different features of Microsoft's Azure Maps library. You can view all 64 maps and the source code for each map at Azure Maps Web Control Samples.
