USDA produces four food plans outlining practical, nutritious diets at successively higher cost levels: the Thrifty, Low-Cost, Moderate-Cost, and Liberal Food Plans. The Thrifty Food Plan serves as the basis for maximum allotments in SNAP.

SNAP Education (SNAP-Ed) is the nutrition education and obesity prevention component of SNAP; its goal is to improve the likelihood that persons eligible for SNAP will make nutritious food choices within a limited budget and choose physically active lifestyles consistent with the current Dietary Guidelines for Americans and the USDA food guidance.

FNS asked Mathematica Policy Research, Inc., (MPR) to assess the CPS estimates in relation to alternative estimates from the Survey of Income and Program Participation (SIPP), which collects longitudinal monthly income data.
