If you have paid attention to the considerable body of scholarly literature on this subject, and if you know Spanish-speaking immigrant communities, the results are utterly unsurprising. But then if you rely on Lou Dobbs, Fox Noise and such for news on immigration, you'll be shocked.
They find "a dramatic increase in English-language ability" across generations, with English used especially at work, while Spanish fares better as home language. This survey and others, taken together,

How is the learning of English today even an issue? Sadly, it still is, as confirmed by a recent Michael Reagan column, here.
