For many Americans who live at or below the poverty threshold, access to healthy foods at a reasonable price is a challenge that often places a strain on already limited resources and may compel them to make food choices that are contrary to current nutritional guidance. To help alleviate this problem, the U.S. Department of Agriculture (USDA) administers a number of nutrition assistance programs designed to improve access to healthy foods for low-income individuals and households. The largest of these programs is the Supplemental Nutrition Assistance Program (SNAP), formerly called the Food Stamp Program, which today serves more than 46 million Americans with a program cost in excess of $75 billion annually. The goals of SNAP include raising the level of nutrition among low-income households and maintaining adequate levels of nutrition by increasing the food purchasing power of low-income families. In response to questions about whether there are different ways to define the adequacy of SNAP allotments consistent with the program goals of improving food security and access to a healthy diet, USDA's Food and Nutrition Service (FNS) asked the Institute of Medicine (IOM) to conduct a study to examine the feasibility of defining the adequacy of SNAP allotments, specifically: the feasibility of establishing an objective, evidence-based, science-driven definition of the adequacy of SNAP allotments consistent with the program goals of improving food security and access to a healthy diet, as well as other relevant dimensions of adequacy; and data and analyses needed to support an evidence-based assessment of the adequacy of SNAP allotments. Supplemental Nutrition Assistance Program: Examining the Evidence to Define Benefit Adequacy reviews the current evidence, including the peer-reviewed published literature and peer-reviewed government reports. Although not given equal weight with peer-reviewed publications, some non-peer-reviewed publications from nongovernmental organizations and stakeholder groups also were considered because they provided additional insight into the behavioral aspects of participation in nutrition assistance programs. In addition to its evidence review, the committee held a data gathering workshop that tapped a range of expertise relevant to its task.

The United States is viewed by the world as a country with plenty of food, yet not all households in America are food secure, meaning access at all times to enough food for an active, healthy life. A proportion of the population experiences food insecurity at some time in a given year because of food deprivation and lack of access to food due to economic resource constraints. Still, food insecurity in the United States is not of the same intensity as in some developing countries. Since 1995 the U.S. Department of Agriculture (USDA) has annually published statistics on the extent of food insecurity and food insecurity with hunger in U.S. households. These estimates are based on a survey measure developed by the U.S. Food Security Measurement Project, an ongoing collaboration among federal agencies, academic researchers, and private organizations. USDA requested the Committee on National Statistics of the National Academies to convene a panel of experts to undertake a two-year study in two phases to review at this 10-year mark the concepts and methodology for measuring food insecurity and hunger and the uses of the measure. In Phase 2 of the study the panel was to consider in more depth the issues raised in Phase 1 relating to the concepts and methods used to measure food security and make recommendations as appropriate. The Committee on National Statistics appointed a panel of 10 experts to examine the above issues. In order to provide timely guidance to USDA, the panel issued an interim Phase 1 report, Measuring Food Insecurity and Hunger: Phase 1 Report. That report presented the panel's preliminary assessments of the food security concepts and definitions; the appropriateness of identifying hunger as a severe range of food insecurity in such a survey-based measurement method; questions for measuring these concepts; and the appropriateness of a household survey for regularly monitoring food security in the U.S. population. It provided interim guidance for the continued production of the food security estimates. This final report primarily focuses on the Phase 2 charge. The major findings and conclusions based on the panel's review and deliberations are summarized.

Few United States government programs are as controversial as those designed to aid the poor. From tax credits to medical assistance, aid to needy families is surrounded by debate—on what benefits should be offered, what forms they should take, and how they should be administered. The past few decades, in fact, have seen this debate lead to broad transformations of aid programs themselves, with Aid to Families with Dependent Children replaced by Temporary Assistance to Needy Families, the Earned Income Tax Credit growing from a minor program to one of the most important for low-income families, and Medicaid greatly expanding its eligibility. This volume provides a remarkable overview of how such programs actually work, offering an impressive wealth of information on the nation's nine largest "means-tested" programs—that is, those in which some test of income forms the basis for participation. For each program, contributors describe origins and goals, summarize policy histories and current rules, and discuss the recipient's characteristics as well as the different types of benefits they receive. Each chapter then provides an overview of scholarly research on each program, bringing together the results of the field's most rigorous statistical examinations. The result is a fascinating portrayal of the evolution and current state of means-tested programs, one that charts a number of shifts in emphasis—the decline of cash assistance, for instance, and the increasing emphasis on work. This exemplary portrait of the nation's safety net will be an invaluable reference for anyone interested in American social policy.

The federal government spends billions of dollars every year on domestic food assistance (FA) programs. The U.S. Dept. of Agriculture administers most of these programs and monitors the prevalence of food insecurity -- that is, the percentage of U.S. households that were unable to afford enough food sometime during the year. Other federal agencies also fund FA programs; however, comprehensive and consolidated information on the multiple programs is not readily available. This report examines: (1) the prevalence of food insecurity in the U.S.; (2) spending on FA programs; (3) what is known about the effectiveness of these programs in meeting program goals; and (4) the implications of providing FA through multiple programs and agencies.

"Daniel Imhoffs recently-published The Farm Bill: A Citizens Guide [is] a welcome and much-needed source for translating farm bill legalese ... [it is] a thorough and navigable history of the farm bill ... [that] hands readers the tools to take action." Foodprint "Dan Imhoff does an extraordinary job of explaining an impenetrable bill with such clarity that we can't ignore the facts: that our current Farm Bill profoundly damages our organic farms, our environment, and our health. Just as extraordinary are the practical solutions Imhoff proposes for fixing the bill--humane policies that would support regenerative agriculture and our local farmers instead of tearing them down." Alice Waters, Executive Chef, Founder, and Owner, Chez Panisse "Cuts to the core of dozens of issues Congress wrestles with every four years, and gives citizens sage advice for making their voices heard in a debate too often dominated by Big Ag, Big Food, and Big Money." Ken Cook, President and Cofounder, Environmental Working Group "A must-read for those who truly care about how they feed themselves and their families." Michel Nischan, Founder and CEO, Wholesome Wave "Readers will gain deep insight into the big barriers to Farm Bill reform, but also into the ripening opportunities for major change. Imhoff makes a strong case for why we should care and what it will take to transform policy." Ferd Hoefner, Strategic Senior Advisor, National Sustainable Agriculture Coalition "Dan Imhoff is the go-to person if you want to know both details and the full sweep of the Farm Bill." Wes Jackson, President Emeritus, The Land Institute.
