*USE geoid TO JOIN DATA DOWNLOADED FROM DATA.CENSUS.GOV* The TIGER/Line Shapefiles are extracts of selected geographic and cartographic information from the Census Bureau's Master Address File (MAF)/Topologically Integrated Geographic Encoding and Referencing (TIGER) System (MTS). The TIGER/Line Shapefiles contain a standard geographic identifier (GEOID) for each entity that links to the GEOID in the data from censuses and surveys. The TIGER/Line Shapefiles do not include demographic data from surveys and censuses (e.g., Decennial Census, Economic Census, American Community Survey, and the Population Estimates Program). Other, non-census, data often have this standard geographic identifier as well. Data from many of the Census Bureau’s surveys and censuses, including the geographic codes needed to join to the TIGER/Line Shapefiles, are available at the Census Bureau’s public data dissemination website (https://data.census.gov/). States and Equivalent Entities are the primary governmental divisions of the United States. In addition to the 50 states, the Census Bureau treats the District of Columbia, Puerto Rico, American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, and the U.S. Virgin Islands as the statistical equivalents of states for the purpose of data presentation. Downloaded from https://www2.census.gov/geo/tiger/TIGER2022/STATE/ on June 22, 2023**使用地理标识符（GEOID）关联从data.census.gov下载的数据集** TIGER/线形状文件（TIGER/Line Shapefiles）是从美国人口普查局主地址文件（Master Address File, MAF）/拓扑集成地理编码与参照系统（Topologically Integrated Geographic Encoding and Referencing, TIGER）（简称MTS）中提取的精选地理与制图信息集合。该类形状文件为每个实体分配了标准地理标识符（GEOID），可与人口普查及调查数据中的GEOID完成关联匹配。TIGER/线形状文件本身不包含普查与调查类的人口统计数据，例如十年一次人口普查、经济普查、美国社区调查以及人口估计项目的数据。此外，诸多非普查类数据集同样带有该标准地理标识符。美国人口普查局诸多普查与调查项目的数据（含可用于关联TIGER/线形状文件的地理编码信息），均可通过该局的公共数据发布网站（https://data.census.gov/）获取。 州及等效实体是美国的主要行政区划单元。除50个州外，美国人口普查局在数据展示场景中，将哥伦比亚特区、波多黎各、美属萨摩亚、北马里亚纳群岛联邦、关岛及美属维尔京群岛视为与州等效的统计单元。 本数据集于2023年6月22日从https://www2.census.gov/geo/tiger/TIGER2022/STATE/ 下载获取。
