Development of the Food-at-Home Monthly Area Prices Data

The Food-at-Home Monthly Area Prices (F-MAP) data product provides detailed food price data to support a broad range of food economics research, supplementing existing public food price data. The data product contains monthly mean unit values and 6 price index measures for 90 food-at-home categories across 10 major metropolitan areas and 4 census regions. This report introduces the USDA, Economic Research Service (ERS) Food Purchase Groups (EFPGs) food classification system and describes the methods used to construct the F-MAP data product using weighted retail scanner data from 2016 to 2018. The F-MAP data product is modeled after the Quarterly Food-at-Home Price Database (QFAHPD) previously published by USDA, ERS to report 1999–2010 food-at-home prices.

家庭食品月度区域价格（Food-at-Home Monthly Area Prices, F-MAP）数据集产品提供详尽的食品价格数据，以支撑各类食品经济学研究，并对现有公开食品价格数据形成补充。该数据集涵盖10个主要大都市区及4个人口普查区域内90个家庭食品品类的月度平均单位价值与6项价格指数指标。本报告介绍了美国农业部（United States Department of Agriculture, USDA）经济研究服务局（Economic Research Service, ERS）的食品购买分组（Food Purchase Groups, EFPGs）食品分类体系，并阐述了基于2016至2018年加权零售扫描数据构建F-MAP数据集产品的方法。F-MAP数据集产品的构建参考了美国农业部经济研究服务局此前发布的、用于披露1999-2010年家庭食品价格的季度家庭食品价格数据库（Quarterly Food-at-Home Price Database, QFAHPD）。
