Habla anglais?

Someone was looking for the percent of people who speak English by country.

I knew that one could check the individual countries in the World Almanac, but that'd be tedious. A better choice, the CIA. I also Googled and found these raw numbers and these from 1995.

Of course, these are often estimates and this article, unlike anything else I came across, suggests that there are more speakers of English in India than in the US. I suppose it depends on how one measures fluency.
