San Francisco language dot maps, 2015.

San Francisco is one of the most multilingual places that I have ever lived. I was curious about who spoke what, and where, so I made some maps in the style of The Racial Dot Map to try to show this data. I also wanted to avoid the rendering issues that The Racial Dot Map has, where certain classes of dots are always drawn on top of other classes of dots -- in these maps, the rendering order of each dot is randomized.

These maps were created using Matplotlib Basemap with data from the U.S. Census Bureau's American Community Survey. They may be used under a CC BY-NC-SA license. Note: the U.S. Census groups multiple languages spoken in and nearby China under the common name "Chinese." As a result, I was unable to differentiate Mandarin, Cantonese, Hokkien, etc.
