Codes and Frequencies
Most IPUMS data transformations are performed using variable harmonization tables that specify how each value in the source data is recoded. Some variables also require programming logic in addition to the harmonization table. The harmonization documents for this variable are:
LANGGN indicates the language or languages in which the respondent is literate: able to read and write. Illiterate persons do not report a language.
Comparability — General
LANGGN differs from language variables in most other samples because of the limitation to literate persons. It does not necessarily report the language the person actually spoke.
There are slightly different universes and some mismatched categories between the samples. The 1983 and 1996 samples refer to specific languages in which the person is literate, while the 2014 sample only indicates whether the person is literate in a national language, a foreign language, or both.
