What about on the street?

Ok, so you saw the map in the post below on the language spoken at home. The next question is, "How are they at speaking English when they leave the home?"

This 2000 Census map shows the concentration of people who speak English "less than well" according to their own evaluation.

Again, the dark green indicates that in those areas somewhere between 43% and 62% consider themselves deficient in the English language.

City-wide they made up 22% of the entire population or 18,821 in 2000. Six years later there are 29.7% of Elginites who speak English "less than well." That's 27,182 people!

Nation-wide 8.1% of the population speak English "less than well" which is either fine evidence of our "diversity" or a strong indication we have created an enclave.

This is not a local problem. Here's a November 2007 report from Pew on the subject:
