KIDBIRTHDAY_ALL (B17_x) variables are 2-digit variables.

99 = NIU (not in universe)

Description

KIDBIRTHDAY_ALL (B17_x) reports the day of the month of the child's birth, according to the Gregorian calendar.

KIDBIRTHDAY_ALL consists of a set of twenty-one separate variables, covering the most recent birth (KIDBIRTHDAY_01) up to the twenty-first-most-recent birth (KIDBIRTHDAY_21) for a female respondent of childbearing age. If KIDBIRTHDAY_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-one births. In many cases, data were hypothetically collected on up to twenty-one births, but no women in the survey had so many births (e.g., no woman had 19, 20, or 21 births). If, for example, no woman in a survey had 21 births and only blank values were included in the original DHS file, then KIDBIRTHDAY_21 would not be available for that survey in IPUMS-DHS.

Comparability

Apart from universe differences, KIDBIRTHDAY_ALL (B17_x) has no comparability problems.

While all samples in KIDBIRTHDAY_ALL use the Gregorian calendar, certain countries use country-specific calendars. These countries (noted below) are excluded from KIDBIRTHDAY_ALL but are included in country-specific variables.

• Ethiopia uses the Ethiopian calendar: KIDBIRTHDAY_ET_ALL
• Nepal uses Vikram Samvat: KIDBIRTHDAY_NP_ALL

KIDBIRTHDAY_ALL (B17_x) is included in Phase VII forward of the standard DHS questionnaire.
