Abstract

The USDA Economic Research Service has monitored food insecurity at national and state levels since 1995 using the Current Population Survey Food Security Supplement. But if a food insecurity measure is to inform action and target interventions, it must be constructed for smaller geographic levels that consider geographic price differences. This article constructs a novel measure of food insecurity using an alternative approach based on financial needs of households, known as the household living budget (HLB). The HLB is defined as the income required to satisfy a household's essential needs, enabling it to maintain a modest yet sufficient standard of living while covering federal and state income taxes. The HLB is constructed at the census tract level and incorporates three key determinants of food insecurity: household size and composition, household income, and food costs. We demonstrate how the HLB along with publicly available data can be used to construct a food insecurity measure using a residual income approach to assess if households are able to afford paying for food expenditures and assess the qualification thresholds of the Supplemental Nutrition Assistance Program (SNAP). Food insecurity estimates are obtained for households in Washington, D.C. and benchmarked to regional results provided by a survey sponsored by the Capital Area Foodbank.

利用家庭生活预算评估小地理区域粮食不安全状况的新方法

自 1995 年以来，美国农业部经济研究局利用当前人口调查食品安全补充资料，对全国和各州的食品不安全状况进行了监测。但是，如果粮食不安全的衡量标准要为行动提供依据并确定干预措施的目标，就必须在较小的地域范围内构建衡量标准，并考虑地域价格差异。本文采用另一种基于家庭经济需求的方法，即家庭生活预算（HLB），构建了一种新的粮食不安全度量方法。家庭生活预算被定义为满足家庭基本需求所需的收入，使其能够在支付联邦和州所得税的同时维持适度但足够的生活水平。HLB 是在人口普查区的层面上构建的，包含了粮食不安全的三个关键决定因素：家庭规模和组成、家庭收入和食品成本。我们展示了如何利用 HLB 和公开可用的数据，采用剩余收入法构建食物不安全度量，以评估家庭是否有能力支付食物开支，并评估补充营养援助计划 (SNAP) 的资格阈值。我们获得了华盛顿特区家庭的粮食不安全估计值，并以首都地区粮食银行发起的一项调查所提供的地区结果为基准。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
