Description

The CFU is the basis of the Hammel/Laslett household classification scheme. CFUs are formed in one of three ways: by a married couple without offspring; by a married couple with never-married offspring and/or never- married adopted/foster children; or by a lone parent with at least one never-married child. If there are more than two generations in a household, the CFU is formed from the youngest generation upwards. Individuals not in a CFU are allocated the code of 0. No individual can be assigned to more than one CFU. A code of 99 means unclassifiable.

For further details on the construction of the CFU see E. A. Hammel and P. Laslett. (1974). "Comparing household structure over time and between cultures." Comparative studies in Society and History 16(1): 73-109.
