This is a 8-digit numeric variable.
SPMFAMUNIT uniquely identifies the family units used to calculate the Supplemental Poverty Measure (SPM).
SPM family units can differ from official poverty units in several ways, including: treating cohabiting partners as members of the same family; treating foster children under age 22 and children under 15 with no identifiable relatives in the household as members of the householder's family; and combining all individuals unrelated to the household head, but who related to one another in the same family unit regardless of the age or marital status.
To identify which SPM family units differ from the family units used to measure official poverty status, see SPMNEWFAM.
For more information on the construction of families used in the SPM, see the Census Bureau's "Unit of Analysis for Poverty Measurement: A Comparison of the Supplemental Poverty Measure and the Official Poverty Measure" report.
