About SNAP Quality Control (QC) data

The SNAP Quality Control data are an edited version of the raw data file generated by SNAP’s QC System, which is composed of monthly case reviews conducted by State SNAP agencies. The SNAP QC data contain detailed demographic, economic, and SNAP eligibility information for a nationally representative sample of SNAP participants. The data, produced annually, are well suited for tabulating characteristics of SNAP participants.

This site provides access to the public use version of the SNAP QC data in SAS, Stata, SPSS, and CSV formats, as well as the accompanying technical documentation and replicate weights.

Access the most recent fiscal year data file, or browse all data files from fiscal year 1996 to the present.

Note: There are three SNAP QC databases for FY 2020. The first covers October 2019 through February 2020, the second covers June through September 2020, and the third combines the first two. Very few States conducted SNAP Quality Control reviews in March 2020 through May 2020, so data for those months are unavailable. In addition, many States do not have data for each month from June through September 2020, so the sum of State participants and benefits do not reflect the full national caseload during that time period. See the 2020 SNAP QC Technical Documentation for more information.
