Socioeconomic data for Forest Service 2020 RPA Assessment

These data provide observed county-level population and personal income data from 2010 and document the projections of those variables over the 2015-2070 period, in five-year increments, for five Shared Socioeconomic Pathways (SSPs) that are the basis for 2020 Renewable Resources Planning Act (RPA) Assessment socioeconomic scenarios. The SSPs are more fully described in the “RPA socioeconomic scenarios summary” document provided in this publication’s Supplemental Information. These data cover the conterminous United States of America.These data are a key set of drivers that are used in multiple natural resource analyses done to meet the legislative requirements of the Forest and Rangeland RPA of 1974. Data from several sources were used to create the historical data and provide national scale guidance for the projections. In fulfillment of the Forest and Rangeland Renewable Resources Planning Act of 1974, the USDA Forest Service periodically assesses the condition and trends of the Nation's renewable resources. These data support the development of future scenarios that are the basis for all resource analyses in the Assessment.Original metadata date was 09/16/2019. On 09/25/2019 the data and metadata were updated to include 2010 data. On 10/17/2023 metadata was updated to include reference to published RPA Assessment.

本数据集包含2010年美国县一级人口与个人收入观测数据，以及针对5种共享社会经济路径（Shared Socioeconomic Pathways, SSPs）的2015-2070年以5年为间隔的变量预测结果；上述路径为2020年《可再生资源规划法案》（Renewable Resources Planning Act, RPA）评估所采用的社会经济情景的核心依据。有关共享社会经济路径的详细说明，详见本出版物补充材料中的《RPA社会经济情景概要》（RPA socioeconomic scenarios summary）文档。本数据集覆盖美国本土48州。
本数据集为满足1974年《森林与牧场可再生资源规划法案》立法要求所开展的多项自然资源分析提供了关键驱动因子集。本数据集的历史数据整合自多源资料，并为全国尺度的预测工作提供了参考依据。
为落实1974年《森林与牧场可再生资源规划法案》，美国农业部（United States Department of Agriculture, USDA）林务局会定期评估美国可再生资源的现状与变化趋势。本数据集支撑了本次评估中所有资源分析所依托的未来情景的构建工作。
本数据集的原始元数据创建于2019年9月16日；2019年9月25日，数据集与元数据完成更新，补充纳入2010年相关数据；2023年10月17日，元数据再次更新，补充了已正式发布的《RPA评估》相关引用。
