This report summarizes research findings from the Food Assistance and Nutrition Research Innovation and Development Grants in Economics Program (RIDGE), formerly known as the Small Grants Program. The Economic Research Service created the program in 1998 to stimulate new and innovative research on food assistance and nutrition issues and to broaden the participation of social science scholars in these issues. The report includes summaries of the research projects that were awarded 1-year grants in summer and fall 2004. The results of these research projects were presented at the October 2005 Small Grants Program conference. The projects examine issues of childhood obesity, food insecurity among vulnerable populations, food assistance program participation and household well-being, and community influence on food assistance and dietary choices. Several of the projects focus on specific populations, such as people living in the rural South and those living on American Indian reservations. The studies summarized herein were conducted under research grants with USDA’s Economic Research Service (ERS) Food and Nutrition Assistance Research Program (FANRP).
