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.
BIRTHSIN1YR (V209) reports the number of births the woman had in the year prior to the survey. This statistic is calculated based on the total number of births in the months 0 to 12 (not 0 to 11) prior to the month of the interview. For example, if the survey were given in January, BIRTHSIN1YR would report the number of births the woman had between the time of the survey and the previous January.
