In 2016, a new Interagency Technical Working Group (ITWG) on improving the SPM was formed to advise on challenges and opportunities brought before it by the Census Bureau and the BLS concerning data sources, estimation, survey production, and processing activities for development, implementation, publication, and improvement of the SPM. Currently, this ITWG is reviewing potential changes to implement in September 2021. One change under consideration by the Working Group is how the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) benefits are valued in the SPM, allowing for state-level variation in the average assistance received by program participants. Using data from the 2018 Current Population Survey Annual Social and Economic Supplement (CPS ASEC), this paper analyzes the impact of using state-varying WIC values instead of national WIC values to estimate SPM rates.
