Respondent's date of birth, in century months (Ethiopian calendar)

DOBCMC_ET is a 4-digit variable.

9998 = Missing
9999 = NIU (not in universe)


Like DOBCMC (V011), DOBCMC_ET reports the century month code (CMC) for the woman's date of birth. However, DOBCMC_ET is country-specific to Ethiopia, as the data are recorded using the Ethiopian calendar. For most other countries, the CMC data for the woman's date of birth are recorded using the Gregorian calendar. On average, there is a seven to eight year gap between the Ethiopian and Gregorian calendars.

For detailed information on the calculation and interpretation of CMC codes, see DOBCMC (V011).


DOBCMC_ET is comparable across Ethiopian samples.

Comparability - Standard DHS

While a standard recode variable reporting the CMC of the woman's date of birth is included in every phase of the DHS data, DOBCMC_ET is country-specific to Ethiopia.
