CBNSUBFAM
Number of subfamilies in household (original Census Bureau classification)
Return to Household Composition variables list

Description

CBSFTYPE reports the number of subfamilies as originally classified by the Census Bureau that the household contains. See the IPUMS subfamilies page for more information on subfamilies and their measurement.

Unlike the IPUMS analogue NSUBFAM, CBNSUBFAM 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.

CBNSUBFAM 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 NSUBFAM.

Comparability

While the concepts measured by CBNSUBFAM 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.
