NFAMS
Number of families in household

Description

NFAMS is a constructed variable that counts the number of families within each unit. A "family" is any group of persons related by blood, adoption, or marriage. An unrelated individual is considered a separate family. Thus, a household consisting of a widow and her servant contains two families; a household consisting of a large, multiple-generation extended family with no boarders, lodgers, or servants counts as a single family.

The universe for this variable, in the U.S. censuses from 1850 to 1930 and the 1940 100% dataset is all sample units, which relies on SAMPRULE. Additionally, the universe for this variable in the 1910-1920 Puerto Rican censuses is SAMPRULE not equal to 4.

Comparability

For persons in households, NFAMS indicates the number of families in the household. For persons in group quarters in the period before 1940, NFAMS indicates the number of families in any sampled unit. From 1850 to 1930 and the 1940 100% dataset, most families can be identified, but for samples from 1940 onward, NFAMS is coded 1 for persons in group quarters. See GQ and "Family Interrelationships" for a discussion of comparability issues.
