As London continues to suffer with perfect weather this weekend, I'm taking a moment to get in from the cool sunny breezes and small cumulus clouds obscuring almost 10% of the sky. Yesterday the temperature soared to an unimaginable 24°C, causing Londoners to seek solace by standing outside pubs in groups drinking lagers. Today things have cooled off to more realistic levels (19°C right now), but the sun continues to make Londoners miserable and wait the restoration of normal weather.
Anyway, I've been meaning to post this map, which shows the U.S. population by race—one dot per person. Here's Chicago:
The yellow area south and west of the Loop are mostly African-Americans; you can see the abrupt change where the Austin neighborhood meets Oak Park on the west side. White people are blue dots, so purple-ish areas are well-integrated, while bluer areas are not.
Other parts of the country have different stories. Play with the map and take a look.
