PREFTIMECH, together with PREFTIMECHVAL, reports the amount of time a woman would like to wait before the birth of a/another child. PREFTIMECH was constructed by combining PREFTIMECHPREG and PREFTIMECHNPREG.

Note that this variable reports only a specific unit of time i.e., months or years, not the actual duration of the interval. The specific number of months or years is reported in PREFTIMECHVAL. Users must use both PREFTIMECH and PREFTIMECHVAL to determine the exact amount of time the woman would like to wait before the birth of a child.

The question associated with this variable was included in the female questionnaire.


There are no comparability issues.
