To create this map, we followed the same process we used to build our worldwide map of population density. This time, though, our goal was to show the geographical distribution of geotagged articles in the English version of Wikipedia, extracting the data from a map built by Mark Graham at the Oxford Internet Institute. There are obvious spatial correlations between the maps, but there are also fascinating differences — places “more interesting” (at least to Wikipedia contributors) than what they population densities would imply.
