State-Level Supplemental Nutrition Assistance Program Expansions During and After the COVID-19 Pandemic, United States, 2020-2023

This dataset contains a state-level record of Supplemental Nutrition Assistance Program (SNAP) expansions adopted during and post the COVID-19 pandemic across all 50 U.S. states and the District of Columbia. It documents the timing, scope, and implementation of major pandemic-related SNAP policies, including Emergency Allotments (EA), Pandemic-Electronic Benefit Transfer (P-EBT), and U.S. Department of Agriculture (USDA)-approved administrative waivers, between March 2020 and August 2023. Data were systematically extracted from the USDA's Food and Nutrition Service (FNS) public database on COVID-19 SNAP waivers (unable to be accessed at time of publication) and harmonized through a structured coding protocol.
