Poverty & Income Volatility

USDA's food and nutrition assistance programs help address the needs of low-income Americans.

ERS examines how income, income volatility, and participation in various food and nutrition assistance programs relate to:

  • economic well-being,
  • diet and nutrition,
  • food security and food spending,
  • child poverty, and
  • food accessibility and the food environment.

ERS has compiled a database of over 1,000 peer-reviewed research reports and articles covering a broad spectrum of food and nutrition assistance research based on both intramural and extramural research published at ERS and elsewhere. The database is searchable by title, lead author, topic, year of publication, data set analyzed and exact word(s) or phrases contained in the publication’s bibliographic citation.
