Comparability — Index

GENERAL
 Mali

Comparability

BIRTHMO (V009) is comparable across all samples except for Ethiopia, where month of birth is reported according to the Ethiopian calendar.

A few samples provided supplemental directions to interviewers when collecting information about date of birth from respondents who were uncertain (as documented below).

Comparability - Standard DHS

The question about month and year of birth is included and consistent across all phases of the standard DHS questionnaire.

Comparability — Mali [top]

The survey form for Mali 1987 prompted interviewers to "probe to get the season if not the month" if the woman knew only her year of birth.
