The Census asks questions about language use at home to locate groups of people who speak a language other than English. Their isolation or integration into a primarily English speaking community can be determined by their ability to speak English proficiently.

* "Other Indo-European" excludes English and Spanish. "Indo-European" is not synonymous with "European." French, German, Hindi, and Persian are all classified as Indo-European. Hungarian, on the other hand, is lumped into "Other Language."

** "Asian Language" includes languages indigenous to Asia and Pacific islands areas that are not also Indo-European languages. Chinese, Japanese, Telugu, and Hawaiian are all classified here.

Also note that ability to speak English "very well" is based on the self-assessment of those responding to Census questions, not on a test of language ability.
