BIRTHINTPOSTMO_ALL (B12_X)
Length of following birth interval, in months
Return to General maternal and infant health variables list

BIRTHINTPOSTMO_ALL (B12_x) variables are 3-digit numeric variables.

Codes

999 = NIU (not in universe)

Description

BIRTHINTPOSTMO_ALL (B12_x) reports the succeeding birth interval, or the length of time in months, after the child was born, until the mother's next birth (i.e., before the child's next youngest sibling).

Because BIRTHINTPOSTMO_ALL relates to the child's younger sibling, last-born children and twins of last-born children are not included in this variable set.

BIRTHINTPOSTMO_ALL consists of a set of nineteen separate variables, covering the second-most-recent birth (BIRTHINTPOSTMO_02) up to the twentieth-most-recent birth (BIRTHINTPOSTMO_20) for a female respondent of childbearing age. If BIRTHINTPOSTMO_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 but the most recent birth for a woman, up to a maximum of her twentieth birth. In many cases, data were hypothetically collected on up to the twentieth births, but no women in the survey had so many births (e.g., no woman had a 19th or 20th birth). If, for example, no woman in a survey had 20 births and only blank values were included in the original DHS file, then BIRTHINTPOSTMO_20 would not be available for that survey in IPUMS-DHS.

Comparability

Apart from universe differences, BIRTHINTPOSTMO_ALL (B12_x) is largely comparable across samples.

Comparability - Standard DHS

BIRTHINTPOSTMO_ALL (B12_x) is included in the standard DHS questionnaire for Phase I forward.

Comparability — Malawi [top]

The 2010 Malawi sample includes several negative intervals. This indicates that, for some women, the birth history is not in the correct order. Researchers should use caution when using the 2010 Malawi sample for this variable.

Comparability — Senegal [top]

The 2010 Senegal sample includes several negative intervals. This indicates that, for some women, the birth history is not in the correct order. Researchers should use caution when using the 2010 Senegal sample for this variable.

Comparability — Yemen [top]

The 2013 Yemen sample includes several negative intervals. This indicates that, for some women, the birth history is not in the correct order. Researchers should use caution when using the 2013 Yemen sample for this variable.
