Description

SFTYPE indicates the type of subfamily (if any) to which each person belongs. See SFRELATE for each person's relationship within the subfamily.

For more information on subfamilies and their measurement, see the Subfamily Overview page.

Comparability

Aside from changes in the definition of group quarters, SFTYPE is perfectly comparable across time. See GQ and "Family Interrelationships" for a discussion of comparability issues.
