2020 Census PL 94-171

2020 Census PL 94-171. The PL 94-171 dataset is the Redistricting Data File created by the U.S. Census Bureau for use by the states in redistricting based on the decennial census. In addition to tabulating the data, our team merged the census data with geographic information, so that it is ready to use in standard mapping softwares. Note these files are too large to use in ESRI mapping softwares and the PL2020_5FILES dataset should be referenced and used instead.2020年美国人口普查PL 94-171数据集。PL 94-171数据集是美国人口普查局（U.S. Census Bureau）基于十年一次人口普查成果编制的选区重划数据文件，专供各州开展选区重划工作使用。本团队除完成数据制表汇总外，还将普查数据与地理信息进行融合，使其可直接适配标准地图绘制软件。需注意，此类文件体积过大，无法在ESRI地图绘制软件中使用，建议参考并改用PL2020_5FILES数据集。
