The Census Bureau defines a linguistically isolated household as on in which no one 14 years old and over speaks only English or speaks a non-English language and speaks English "very well." In other words, all members of the household 14 years old and over have at least some difficulty with English.
Some national-level highlights from the collection of tables titled America Speaks: A Demographic Profile of Foreign-Language Speakers for the United States: 2000, include:
- Out of 97,454,100 total U.S. households, a language other than English was spoken in 14,005,410, of which 3,026,542 households were classified as linguistically isolated.
- Among households with combined annual incomes of $15,000 or less, 1,068,734 were linguistically isolated, compared to only 105,871 households with incomes of $100,000 or more.
- In 2,110,214 of the total 3,026,542 households classified as linguistically isolated, the head of the household was a native-born American, compared to 916,328 in which the head of the household was foreign-born.
