Mathematica’s nutrition research uncovers evidence to help improve food and nutrition support for individuals, families, and communities. From the studying the effects of targeted taxes on consumption of sugar-sweetened beverages to examining the impact of providing employment and training services to participants in the Special Nutrition Assistance Program (SNAP), we partner with federal, state, and local decision makers on their journeys from inquiry to insight.
Mathematica’s expertise ranges from evaluating programs meant to prevent childhood obesity, promote consumption of fruits and vegetables, and improve household food security to conducting microsimulations of changes to SNAP eligibility requirements. Drawing from a toolbox that ranges from rapid-learning approaches to complex random assignment evaluations, we bring rigor and objectivity in collaborating with our partners.
Evaluation of SNAP Employment and Training Pilots
The Supplemental Nutrition Assistance Program (SNAP) is the primary source of nutrition assistance for many low-income people. Beyond providing access to food assistance, SNAP also provides some participants with a critical work support, helping them during times of unemployment or underemployment.
Multi-City Evaluation of Sugar-Sweetened Beverage (SSB) Taxes
This study evaluated the implementation and impact of these taxes in four cities, primarily in Philadelphia and Oakland, with additional analysis in San Francisco and Seattle.
