American Indian Reservations in Arizona

A federal Indian reservation is an area of land reserved for a tribe or tribes under treaty or other agreement with the United States, executive order, or federal statute or administrative action as permanent tribal homelands, and where the federal government holds title to the land in trust on behalf of the tribe. Off-reservation trust land is real estate that is held by the US Department of the Interior for the benefit of a Native American tribe or a member of a tribe, but is not located within an Indian reservation. Off-reservation trust land can be used for a variety of purposes, including: Housing, Agriculture or forestry, Community services like health care and education, Governmental operations, and Cultural activities. Native Nation refers to the indigenous people group itself, with its own political structure and sovereignty, allowing them to govern their affairs within their tribal boundaries. A "tribal reservation" is a specific geographic area of land designated for a Native American tribe to live on, while a "Native Nation" refers to the tribe itself, which is a sovereign political entity with its own government and culture, regardless of whether they reside on a reservation or not; essentially, the reservation is the land, and the Native Nation is the people and their governing body that inhabit it. Example: The Navajo Nation is a Native Nation, and the Navajo Reservation is the specific land area where a large portion of the Navajo people reside. Data Source: The Census Bureau obtains the boundary and attribute information for tribal subdivisions on federally recognized American Indian reservations and off-reservation trust lands from federally recognized tribal governments through the Census Bureau's Boundary and Annexation Survey (BAS). ADHS added the native nation information for each reservation provided by the agency's tribal liaison. Update Frequency: Every 10 years with the decennial census.联邦印第安人保留地（federal Indian reservation）指依据与美国签订的条约、其他协议、行政命令、联邦法规或行政行动，为单个或多个印第安部落预留的永久部落定居家园土地区域，且该土地的所有权由联邦政府以信托形式代部落持有。保留地外信托土地（off-reservation trust land）指由美国内政部（US Department of the Interior）为印第安部落或部落成员持有产权的不动产，但该不动产并不坐落于印第安人保留地范围内。保留地外信托土地可用于多种用途，涵盖住房、农业或林业、医疗保健与教育等社区服务、政府运营以及文化活动。原住民部落（Native Nation）指拥有自身政治架构与主权的原住民群体，可在部落管辖边界内自主管理内部事务。“部落保留地（tribal reservation）”指为印第安部落划定的供其居住的特定地理区域；而“原住民部落（Native Nation）”则指代作为拥有自身政府与文化的主权政治实体的部落本身，与其成员是否居住在保留地范围内无关。简言之，保留地是土地载体，原住民部落则是居住于该土地上的民众及其治理机构。示例：纳瓦霍部落（Navajo Nation）即为典型的原住民部落，纳瓦霍保留地（Navajo Reservation）则是纳瓦霍族多数民众定居的特定土地区域。数据来源：美国人口普查局（Census Bureau）通过其边界与吞并调查（Boundary and Annexation Survey, BAS），从联邦认可的部落政府处获取联邦认可的美国印第安保留地及保留地外信托土地的部落分区边界与属性信息。ADHS补充了由该机构部落联络官提供的各保留地的原住民部落相关信息。更新频率：每十年一次，与十年一次的全国人口普查同步开展。
