SPM unit's work expenses - not capped


Information on the codes for this variable is not currently available.


SPMWKXPNS reports family work expenses and is used in the construction of the Supplemental Poverty Measure (SPM). Work expenses are estimated using the reported number of weeks worked by members of the SPM family unit.

For more information on the estimation of work and child care expenditures for the SPM, see the Census Bureau's "The Research Supplemental Poverty Measure" report.


Aside from the effects of inflation, SPMWKXPNS is comparable across years from 2010 to 2018.

In 2019, the Census Bureau implemented a new processing system to accommodate survey changes. These changes affect income and relationship variables, making poverty measurements before and after 2019 incomparable. For more information on this overhaul, see our guide to the 2019 ASEC updates.
