KIDTWIN_ALL (B0_x) variables are 2-digit variables.

0 = Single birth
10 = Twin or multiple birth
11 = 1st of multiple births
12 = 2nd of multiple births
13 = 3rd of multiple births
14 = 4th of multiple births
15 = 5th of multiple births
16 = 6th of multiple births
99 = NIU (not in universe)

Description

KIDTWIN_ALL (B0_x) reports whether the child is a twin (or born in a multiple birth) or is a singleton (single) birth.

KIDTWIN_ALL consists of a set of twenty separate variables, covering the most recent birth (KIDTWIN_01) up to the twentieth-most-recent birth (KIDTWIN_20) for a female respondent of childbearing age. If KIDTWIN_ALL is included in a data extract, all these separate variables are included in a researcher's data file.

Information for this variable was collected on all births for a woman, up to a maximum of twenty. In many cases, data were hypothetically collected on up to twenty births, but no women in the survey had so many births (e.g., no woman had 19 or 20 births). If, for example, no woman in a survey had 20 births and only blank values were included in the original DHS file, then KIDTWIN_20 would not be available for that survey in IPUMS-DHS.

Comparability

Apart from universe differences, KIDTWIN_ALL (B0_x) has no comparability problems.

Comparability - Standard DHS

KIDTWIN_ALL (B0_x) is included in every phase of the standard DHS questionnaire.
