Here’s a map of the population of Austinites who report speaking English less than “very well.”
You can see that all of the east side Council districts have at least 21% who report speaking English less than “very well.” The district with the highest proportion of non-English speakers is Greg Casar’s District 4.
I’m less struck by the high percentage of non-English speakers in some areas than by how few of them there are in West Austin.
