Language Spoken at Home is a data set published by the United States Census Bureau on languages in the United States. It is based on a three-part language question asked about all household members who are five years old or older. The first part asks if the person speaks a language other than English at home. If the answer is 'yes,' the respondent is asked what that language is. The third part of the question asks how well the person speaks English ("Very well,' "Well," "not well," "Not at all").
The three-part question was first asked in 1980; It replaced a question about mother tongue. In 2000, the language question appeared on the long-form questionnaire which was distributed to 1 out of 6 households. After the long form census was eliminated (after the 2000 census), the language question was moved to the American Community Survey (ACS). The language questions used by the US Census changed numerous times during 20th century. Changes in the language questions are tied to the changing ideologies of language in addition to changing language policies.
The published data varies in the amount of detail provided each year.
In 2000 and 1990, language spoken was a part of Summary File 3. For the 2000 census, data was published for 30 languages, chosen for their nationwide distribution, and 10 language groupings (see list below). Data from households which report languages other than the 30 are reported under the language groupings. Thus, languages which are widespread in certain areas of the country but not nationally get put together, even in block level data. Lithuanian, and Welsh are simply "Other Indo-European languages," Yoruba and Swahili are simply "African languages," and Indonesian and Hakka are simply "Other Asian languages." Several locally very well represented languages, such as Punjabi and Pennsylvania German, are collated into smaller groupings. Native North American languages besides Navajo are also collated, though they are reported on several geographic levels in another data set.
For the 2009-2013 ACS data, detailed information was provided on over 300 languages. In addition to the number of speakers reported for each language, the count of speakers whose English speaking ability is less than "very well" is also reported.
Updated information is available via the Census Bureau's American Fact-finder.
Statistics on English-speaking ability and language spoken at home are used by the Justice Department in the implementation of the Voting Rights Act and to allocate funds for to schools for programs for English Language Learners. Federal and local governments, as well as non-governmental and private interests also use these statistics.
