KIDDOBCMC (B3_x) variables are 4-digit variables.

Codes

9999 = NIU (not in universe)

Description

KIDDOBCMC_AF_ALL (B3_x) reports the century month code for the date of birth of the child, according to the Solar Hijri calendar. This variable is only available for the Afghan samples.

KIDDOBCMC_AF_ALL consists of a set of twenty separate variables, covering the most recent birth (KIDDOBCMC_01) up to the twentieth-most-recent birth (KIDDOBCMC_20) for a female respondent of childbearing age. If KIDDOBCMC_AF_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 KIDDOBCMC_20 would not be available for that survey in IPUMS-DHS.

Comparability

KIDDOBCMC_AF_ALL (B3_x) has no comparability problems across Afghan samples.

All standard date variables in Afghanistan DHS samples are given in the Solar Hijri calendar. The Solar Hijri calendar year consists of 12 months of 29 to 31 days. The first 6 months (Hamal through Sonbola) each contain 31 days, the following 5 months (Mizan through Dalvae) each contain 30 days, and the last month (Hut) contains 29 days (30 in a leap year). The Solar Hijri calendar begins on the March equinox, which usually falls around March 21 in the Gregorian calendar. In general, the Solar Hijri calendar is 621 or 622 years behind the Gregorian calendar.

Comparability - Standard DHS

KIDDOBCMC_AF_ALL (B3_x) is a standard recode variable included in every phase of the DHS data for Afghan samples.
