Description

CBSFTYPE reports the type of subfamily as originally classified by the Census Bureau. See the IPUMS subfamilies page for more information on subfamilies and their measurement.

Unlike the IPUMS analogue SFTYPE, CBSFTYPE is not based on the family interrelationship variables, and it does not identify unrelated subfamilies. Furthermore, the Census Bureau's procedures for identifying subfamilies are known to be unreliable, and only with the more recent ACS data do their procedures appear to yield consistent results.

CBSFTYPE is useful mainly for users attempting to match the Census Bureau's summary files or published estimates; other users--particularly those analyzing change over time--are encouraged to use SFTYPE.

Comparability

While the concepts measured by CBSFTYPE have not changed over time, the Census Bureau's procedures for identifying subfamilies have changed dramatically over the years. See this article for more information.
