Description
LANGMX indicates the indigenous language, if any, spoken by the person for all the Mexico samples.
Comparability — General
LANGMX is not fully comparable, because the number of identified languages changes over time. The first two digits place the language in its family group according to the 2000 Census classification.
The 1990 categorization is very similar to that for 2000, but it includes some additional languages within the groups. The 2010, 2015 and 2020 codes were different, but similar in content and detail to the 1990 and 2000 samples. The 1970 census identifies many fewer languages, and does not include representative languages from every group.
There are minor universe changes of age across samples.
The variable SPEAKIND indicates whether the person speaks Spanish as well as an indigenous language.
