Ideal duration for a couple to wait before starting sexual relations after the birth of a child. The first digit gives the units in which the respondent answered, while the last two digits give the time in those units. The units codes are: 1 - months, 2 - years, 9 - special answers. If the units value is 9 then the variable contains a special response, and if the duration value is greater than 90 this also indicates a special response. For example, code 996 is used for "other" answers, and code 299 would mean that the response was given in years but the actual duration was missing on the questionnaire.
