DC is most definitely a transplant town, attracting all walks of life from around the world. It’s interesting to see how this translates into languages spoken throughout the city, as a recent map using census tract-level data from the American Community Survey shows. Developed by Randy Smith, GIS specialist at Hood College, it shows just how much linguistic variety there is in the area.
You can see that large swaths of the city speak African Languages, Vietnamese, and French, though 23 languages (other than English and Spanish, remember) color the map across the board. You can also view the map without solely English (which shows, except for a few small pockets, that Spanish is the main second dominant language) and all languages (where English looks to be about 98% of the map). It does well to illuminate the communities tucked in each neighborhood in DC, and while perhaps it’s not surprising, it’s certainly fascinating.
