All women who want another child (V602 = 1), plus those originally responding that they want another child, but then say they cannot get pregnant (see also V602).
This variable records the original response to the question "How long would you like to wait from now before the birth of another child?" The first digit gives the units in which the respondent answered (1 indicates months, 2 indicates years, and 9 indicates a special response), while the last two digits give the time in those units. 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 994 is used for the responses "Soon/Now", and code 299 would mean that the response was given in years but the actual duration was missing on the questionnaire.
