Editing Language Spoken at Home (section)

== Data published ==
The published data varies in the amount of detail provided each year. 

In [[2000 United States census|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 language|Lithuanian]], and [[Welsh language|Welsh]] are simply "Other Indo-European languages," [[Yoruba language|Yoruba]] and [[Swahili language|Swahili]] are simply "African languages," and [[Indonesian language|Indonesian]] and [[Hakka language|Hakka]] are simply "Other Asian languages." Several locally very well represented languages, such as [[Punjabi language|Punjabi]] and [[Pennsylvania Dutch language|Pennsylvania German]], are collated into smaller groupings. Native North American languages besides [[Navajo language|Navajo]] are also collated, though they are reported on several geographic levels in another data set.  

For the 2009-2013 ACS data, [https://www.census.gov/data/tables/2013/demo/2009-2013-lang-tables.html 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.
