2020 Census State Redistricting Data - Group Quarters Population for Block Groups

For more information about this layer please see the GIS Data Catalog. US Census 2020 File03 (Table P5), Subjects Group Quarters Population by Major Group Quarters Type. A unique logical record number (LOGRECNO in the geographic header) is assigned to all files for a specific geographic entity. This field is the key that links records across all four files. Besides the logical record number, other identifying fields also are carried over from the geographic header file to the table files. These are file identification (FILEID), state/U.S. abbreviation (STUSAB), characteristic iteration (CHARITER), and characteristic iteration file sequence number (CIFSN). The geographic header is standard across all electronic data products from the 2020 Census. Note that some fields in the Redistricting products are not filled. For example, the CHARITER field is used in other 2020 Census products; in the 2020 Census State Redistricting Data (Public Law 94-171) Summary File, it is always coded as 000, GEOIDs are Census Block Groups. For table P5 details refer to the online census documentation: 2020 Census State Redistricting Data (Public Law 94-171) Summary File

如需了解该图层的更多信息，请参阅地理信息系统（GIS）数据目录。本文件为美国2020年人口普查文件03（表P5），主题为按主要集体宿舍类型划分的集体宿舍人口。所有针对特定地理实体的文件均分配有唯一逻辑记录编号（地理表头中的LOGRECNO），该字段是关联四个文件中所有记录的关键纽带。除逻辑记录编号外，其他标识字段也从地理表头文件迁移至表格文件，包括文件标识（FILEID）、州/美国标准缩写（STUSAB）、特征迭代编号（CHARITER）以及特征迭代文件序列号（CIFSN）。该地理表头是2020年人口普查所有电子数据产品的统一标准格式。请注意，选区重划产品中的部分字段未填充内容：例如，CHARITER字段在其他2020年人口普查产品中被使用；在2020年人口普查州选区重划数据（公法94-171）汇总文件中，该字段始终被编码为000，地理标识符（GEOIDs）对应普查街区组。如需了解表P5的详细信息，请参阅在线普查文档：2020年人口普查州选区重划数据（公法94-171）汇总文件
