Eric Fischer has updated his superb maps of ethnicity based on the newly released 2010 US census block results. These pointillist images, covering more than a hundred cities, depict every 25 residents as a single dot. Each coloured according to ethnicity: Red is White, Blue is Black, Green is Asian, Orange is Hispanic, Yellow is Other.
The dots are placed randomly within census block areas giving the maps a slightly diffuse appearance. but as Eric explains it’s probably a much more realistic portrayal of the complexity of city life than the often harshly delineated boundaries shown elsewhere.
