Explore how IPUMS created this variable
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:
- Harmonization table
- Supplemental programming
- Instructions for interpreting harmonization documents

Comparability — General
There are significant universe differences between samples. Most samples limit the question to women of child bearing age, and some to ever-married women. Most importantly, some samples restrict the universe to births within the previous 12 to 24 months, while the others ask about sex of the last birth regardless of when it occurred.
Some samples lack information on multiple births.
Comparability — China [top]
The China sample restricts responses to births within the last 18 months.
Comparability — Kenya [top]
The universe for all samples is females age 12+ who gave birth.
Comparability — Laos [top]
The 2015 sample restricts responses to women age 15-49 who ever gave birth.
Comparability — Lesotho [top]
The universe differs across samples. In 1996, females age 12+ who ever gave birth are included. In 2006, only females age 12 to 49 who ever gave birth are included.
Comparability — Myanmar [top]

Comparability — Uganda [top]
The Uganda samples both restrict responses to females age 12 to 54 who ever given birth.
Comparability — Vietnam [top]
The variable is fully comparable across samples. The data for each sample are derived from two source variables: one for males and one for females.
