Mapping U.S. population change

Detroit population change 2000-2010, from www.datapointed.netIn a beautiful series of watercolour-like maps, Stephen von Worley illustrates population change in the USA over the past ten years.

Using custom-built cartographic software and data from the 2010 US census he has created twenty high resolution graphics of major cities, also one for the contiguous States.  The images show census tracts colour-coded according to population change – deep blue represents decrease, red indicates an increase.

The flight of Americans to the suburbs is a well known phenomenon – notice the blue ring circling deep red in the above thumbnail of Detroit. But look closely at the centre of the city – the blue speckles mark an upturn in numbers of residents in the downtown area. Similar growth rings are visible in other cities.
