Notes
Preferred waiting time before the birth of another child is created from two variables, the first asking how long from the date of interview the respondent would like to wait before the birth of the next child. If the respondent answered "Don' t know" or gave an "Other" answer when she was asked how long she would like to wait for her next child, then she was asked how old she would like her youngest child to be when the next child is born, and the response to this is converted into a number of years before the next child is wanted. If the respondent replied to the second question that she had no children then the variable is set to missing. In some countries there may be some additional non-numeric responses to the question of how long to wait before the next birth. These are assigned additional codes on a country-specific basis.
