Description

LASTBIRTHYR reports the year the woman's most recent child was born.

Enumerators were instructed to enter the date as January 1st, 2020 (January 1st, 2030 for samples in 2019 or after) if the respondent did not give a response to the associated survey question. IPUMS has recoded these cases to "No response or missing". Additionally, IPUMS has recoded years that were in the future at the time of the interview as "Logical edit - missing". For example, values of 2018 or later in samples from 2016 have been recoded. For some samples, interviews were conducted across two years, for example, some 2016 samples include interviews from early 2017.
The question associated with this variable was included in the female questionnaire. For maternal and newborn health samples, this question was included in the female baseline survey.
