His map of Washington is just one of 94 maps he's made of the most populated cities in the United States, basing his project on Harvard graduate student Bill Rankin's 2009 map titled Chicago Boundaries, (below) which plotted the demographics of the city according to race and income.
Rankin originally plotted his map of Chicago for a Yale journal article that asked him to explore how maps construct reality. He said neighborhoods are usually defined by solid colors plotted on a street map, but in reality the divisions are much blurrier. He wanted to to show demographics on a map.
The dots represent 25 people each and are accorded colors to represent each race or ethnicity. Red dots are people who marked white on the census; blue represents black people; green represents Asians; orange is Hispanic; and gray is other.
Rankin noted that he didn't plot income. He intended his original project to show how race and income divisions don't always overlap. "You'd never see as nearly as stark boundaries of income," he said. "There is much more stark discrimination of races."
Check out all of the maps in Fischer's set here. Fischer said he looks forward to the 2010 Census data to see how the maps have changed.
If the maps look somewhat familiar, Fischer was behind the Locals and Tourists maps that made the Internet rounds in June. He mined the geotags of photographs and plotted where tourists and locals take photos in a city.
