US State Boundaries

This dataset represents States and equivalent entities, which are the primary governmental divisions of the United States. The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. In addition to the fifty States, the Census Bureau treats the District of Columbia, Puerto Rico, and each of the Island Areas (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.

本数据集展现了美国的州及其等价实体，它们构成了美国主要的政府行政区域。TIGER/Line 形状文件及相关数据库文件（.dbf）是从美国人口普查局的主地址文件/拓扑集成地理编码与参照（MAF/TIGER）数据库（MTDB）中提取的选定地理和制图信息的集合。MTDB 构成一个无缝的全国性文件，各部分之间无重叠或间隙。然而，每个 TIGER/Line 形状文件均设计为独立的数据集，也可组合使用以覆盖整个国家。除五十个州外，人口普查局还将哥伦比亚特区、波多黎各以及各岛屿地区（美属萨摩亚、北马里亚纳群岛联邦、关岛和美属维尔京群岛）视为在数据展示中的州级统计等价物。
