Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
Preferred waiting time before the birth of another child is created from a single question 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, she is no longer asked how old she would like her youngest child to be when the next child is born. 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.
