2010 Census Tracts

This shows the boundaries for American Indian reservations, counties, tracts, block groups, blocks, military boundaries and political townships along with the associated demographic statistics collected in the 2010 Census. 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. The primary legal divisions of most states are termed counties. In Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau. In four states (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their states. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation.

本数据集展示了美国印第安人保留地、县（county）、普查片区（tract）、街区组（block group）、街区（block）、军事辖区与政治镇区的边界，以及2010年人口普查采集的关联人口统计数据。本数据集所采用的TIGER/Line形状文件及关联数据库文件（.dbf），均取自美国人口普查局主地址文件/拓扑综合地理编码与参照（MAF/TIGER）数据库（MTDB）中筛选后的地理与制图信息。MTDB为无缝衔接的全国性数据集，各部分之间无重叠与空隙；但每份TIGER/Line形状文件均可作为独立数据集单独使用，也可拼接覆盖全美范围。美国多数州的主要法定行政区划为县（county）。在路易斯安那州，此类行政区划被称为堂区（parish）。阿拉斯加州未设县，其等效行政区划为建制自治市镇、市自治市镇、自治市；而在阿拉斯加的非建制地区，等效行政区划为普查区域（census area），此类区域由阿拉斯加州与人口普查局为统计目的协同划定。在马里兰州、密苏里州、内华达州与弗吉尼亚州，存在一个或多个独立于任何县行政区划的建制地区，它们构成所在州的一级行政区划，此类建制地区被称为独立市，在数据展示中被视为等效行政区划单元。完整的堪萨斯州地理空间目录由堪萨斯州数据获取与支持中心（DASC）管理，可通过以下网址获取：https://hub.kansasgis.org/
