AGEFORM_ALL (M23_X)
Age (in months) for formula or other milk

AGEFORM_ALL variables are 2-digit variables.

See AGEFORM_01 for the relevant codes.

Description

For women who gave birth in the last three to five years, AGEFORM_ALL (M23_x) reports the age, in months, at which the child was first given baby formula or kinds of milk other than breast milk on a regular basis.

AGEFORM_ALL consists of a set of up to six separate variables, covering the most recent birth (AGEFORM_01) up to, potentially, the sixth-most-recent birth (i.e., AGEFORM_02, AGEFORM_03, AGEFORM_04, AGEFORM_05, and AGEFORM_06) during the reference period prior to the survey. If AGEFORM_ALL is included in a data extract, all these separate variables are included in a researcher's data file.

The information in AGEFORM_ALL was collected for all births within the reference period preceding the survey. In many cases, data were hypothetically collected on up to six births, but no women in the survey had so many births (e.g., no woman had 4 or more births in 3 years, or had 5 or 6 births in 5 years). If, for example, no woman in a survey had 6 births in five years and only blank values were included in the original DHS file, then AGEFORM_06 would not be available for that survey in IPUMS-DHS.
For some samples, noted in the Comparability section, this information was collected on only the last-born child (AGEFORM_01).

Comparability

Apart from universe differences, AGEFORM_ALL (M23_x) has no comparability problems.

Comparability - Standard DHS

AGEFORM_ALL (M23_x) is included in the standard DHS questionnaire for Phase 2 only.

Comparability — Sudan [top]

The 1989 Sudan survey collected this information for the last-born child only (AGEFORM_01).

Comparability — Yemen [top]

The 1991 Yemen survey asks separately about the age for powdered milk and animal milk. The responses to these two questions are consolidated in AGEFORM_ALL.
