For all persons who are eligible for data collection in the round, FAMSZERD reports the number of persons associated with a single family unit in round. FAMSZERD is calculated after students are linked to their associated parent RUs for analytical purposes. This variable is appropriate for family-level analyses, though users should note that persons ineligible for data collection are not included.
FAMSZERD is a two-digit numeric variable.
