The National Household Food Acquisition and Purchase Survey was the first nationally representative survey of American households to collect unique and comprehensive data about household food choices and expenditures. Mathematica collected information from 4,826 households over a seven-day period about foods acquired for home preparation and consumption; foods acquired and consumed away from home; and household characteristics, including income, nonfood expenditures, food security, health status, and diet and nutrition knowledge. The survey included data from Supplemental Nutrition Assistance Program (SNAP) households, low-income households not participating in SNAP, and higher income households.
