A linguistically isolated household is one in which no member 14 years old and over (1) speaks only English or (2) speaks a non-English language and speaks English “very well.” In other words, all members 14 years old and over have at least some difficulty with English.

Source of data: IECAM, based on several estimates from the Census Bureau
Note: Languages are those used by U.S. Census Bureau, American Community Survey.
Note: Data are based on answer to questions: “Does this person speak a language other than English at home?” and “What is this language?”
Note: For children age 5, use language of child. For children under age 5, use language of mother; if not mother present, use language of father; if no father present, use language of head of household; if no head of household present, indicate unknown. Thus, the data represent the language spoken by the child or likely being learned by the child.
Note: The fact that a child is reported as speaking or learning one of these non-English languages does not imply that the child does not know or is not learning English also.
