Where do people use iPhones, Android phones, Blackberries, and other devices? In our region, it appears Android is far more popular on the east side of the region than the west:

Click to toggle: All devices  iPhone only  Android only

Tom MacWright, who has written for Greater Greater Washington about open laws, made the tool for MapBox using 280 million Tweets, each of which has information about which kind of device the tweeter was using.

I initially expected to see a big blob of purple (Blackberry) in the federal core, but there is none; probably this is a combination of many federal agencies moving to iPhones, and federal workers not using their government phones for tweeting.

But really, these maps look awfully similar to the same maps of DC’s demographic divides:

Update: Several commenters noted that the combined map seems to overlay iPhones over Androids, so green areas are really areas with Androids but fewer iPhones. I’ve added a toggle to switch between the combined map, iPhone-only, and Android-only.
