SPMNPERS_19RYALT

SPM unit's number of persons (2019 SPM reference year)

Codes

SPMNPERS_19RYALT is a 2-digit numeric variable.

Description

SPMNPERS_19RYALT records the total number of persons in the family unit used to calculate the Supplemental Poverty Measure (SPM). The SPM family units, identified in SPMFAMUNIT_19RYALT, are defined differently from the family units used to calculate official poverty.

This variable is an alternative version of SPMNPERS that was re-released for the 2020 ASEC which reflects methodological changes first introduced with the 2021 CPS ASEC sample. For more information, see our documentation on the re-release of the 2019 SPM research file in the 2020 ASEC that describes methodological improvements that impact SPM resource and threshold variables. The SPM reference year is the calendar year to which the income, taxes, transfers, expenses, and poverty thresholds apply.
