This report fills a request for a study of food deserts-areas with limited access to affordable and nutritious food-from the Food, Conservation, and Energy Act of 2008. The report summarizes findings of a national-level assessment of the extent and characteristics of food deserts, analysis of the consequences of food deserts, lessons learned from related Federal programs, and a discussion of policy options for alleviating the effects of food deserts. Overall, findings show that a small percentage of consumers are constrained in their ability to access affordable nutritious food because they live far from a supermarket or large grocery store and do not have easy access to transportation.

Results from reviewed studies indicate that for most participants in the Food Stamp Program-children, nonelderly men, and the elderly-use of food stamp benefits does not result in an increase in either Body Mass Index (BMI) or the likelihood of being overweight or obese. However, for nonelderly women, who account for 28 percent of the food stamp caseload, some evidence suggests that participation in the Food Stamp Program may increase BMI and the probability of obesity. Different results for age and sex subgroups remain unexplained. Further, because food stamp benefits are issued to households, not individuals, mixed results across age and sex subgroups make it difficult to target policy alternatives to address potential weight gain among some participants while not affecting others in the household.

Disparities in health and health care across racial, ethnic, and socioeconomic backgrounds in the United States are well documented. The reasons for these disparities are, however, not well understood. Current data available on race, ethnicity, SEP, and accumulation and language use are severely limited. The report examines data collection and reporting systems relating to the collection of data on race, ethnicity, and socioeconomic position and offers recommendations.

One of the most substantial policy changes in the past decade was the elimination of the main social welfare program for poor families, Aid to Families with Dependent Children, ending the entitlement to cash benefits and replacing it with a policy emphasizing work. A question relevant for understanding the consequences of this policy change is how the time allocation among work and family care activities of poor families has changed. President Clinton's proposed budget for fiscal 2001 includes funds for the Bureau of Labor Statistics (BLS) to develop a survey to measure how Americans spend their time (U.S. Department of Labor, 2000). BLS has already explored the feasibility of such a survey. In 1997, a pilot study that collected time-use data for a sample of Americans was conducted, and the results of that study were presented at a 1997 conference sponsored by BLS and the MacArthur Network on the Family and the Economy. Using knowledge gained from the pilot study and the conference, BLS published a report on the feasibility of a national time-use survey and developed a proposal to conduct the survey. Time-Use Measurement and Research is a summary of a workshop convened to consider data and methodological issues in measuring time use. This report discusses why time-use data are needed, highlighting many of policy and behavioral applications of time-use data. It also summarizes conceptual issues covered during the workshop, discusses a framework for how individuals and households allocate their time, and comments on some conceptual issues in measuring time use.
