Definition
The preferred waiting time to the next birth is grouped into 12-month categories with responses of more than six years coded as 6+ years. Non-numeric responses are coded into one group (7 "Non-numeric"), but with "Don't know" and missing responses in their own categories (8 & 9). The additional response "Soon/Now" is not grouped with the other nonnumeric codes, but is recoded as less than one year waiting time.
