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.
BIOIDX (V419) reports the number of entries (number of children) in the height and weight table. This number is typically equal to the number of births in the three (BIRTHSTOT3YR (V238)) or five (BIRTHSIN5YRS (V208) years before the survey. While there is, theoretically, no limit to the number of births recorded in BIRTHSTOT3YR and BIRTHSIN5YRS, BIOIDX is actually limited to the number of columns on the survey form that can be completed. In most cases, BIOIDX is capped at six.
