Whether there were any other live births in the interval between the birth and the previously reported birth.
Note: Variables B14 and B15 are questions used in the interview to try and ascertain if the respondent had omitted any live births while reporting her birth history. The birth history may have been modified during the interviewing process, and the responses may not now correspond to the interval between the birth and the preceding birth recorded in this section. The data have been included to help indicate cases where the respondent may have omitted live births while originally reporting the birth history. The omitted births should be included in this final version of the birth history.
