Comparability
In addition to slight differences in question wording, LITLANGUAGE differs across samples in the available response categories.
To maximize comparability across samples, IPUMS-DHS uses composite coding for this variable. For example, French and Arabic responses share a common first digit of "3"; the second digit provides additional detail, if available (e.g., "French" is code "11" and "Arabic" is code "12").
Comparability - Standard DHS
LITLANGUAGE is a country-specific variable, and it is not included in any phase of the standard DHS questionnaire.
