2020 Neighborhood Tabulation Areas (NTAs)

2020 Neighborhood Tabulation Areas (NTAs) are medium-sized statistical geographies for reporting Decennial Census and American Community Survey (ACS). 2020 NTAs are created by aggregating 2020 census tracts and nest within Community District Tabulation Areas (CDTA). NTAs were delineated with the need for both geographic specificity and statistical reliability in mind. Consequently, each NTA contains enough population to mitigate sampling error associated with the ACS yet offers a unit of analysis that is smaller than a Community District. Though NTA boundaries and their associated names roughly correspond with many neighborhoods commonly recognized by New Yorkers, NTAs are not intended to definitively represent neighborhoods, nor are they intended to be exhaustive of all possible names and understandings of neighborhoods throughout New York City. Additionally, non-residential areas including large parks, airports, cemeteries, and other special areas are represented separately within this dataset and are assigned codes according to their type (See NTAType field).

2020年社区制表区域（Neighborhood Tabulation Areas, NTAs）是用于发布十年一次人口普查（Decennial Census）与美国社区调查（American Community Survey, ACS）数据的中型统计地理单元。2020年NTAs通过聚合2020年人口普查区（census tracts）生成，并嵌套于社区分区制表区域（Community District Tabulation Areas, CDTA）范围内。NTAs的划定兼顾地理精准性与统计可靠性的双重需求。因此，每个NTA均拥有足够的人口规模以抵消ACS相关的抽样误差，同时提供了比社区分区更小的分析单元。尽管NTA的边界与关联名称大致契合纽约民众普遍认知的诸多社区，但NTAs并非旨在确切表征社区，也并非旨在穷尽纽约市所有可能的社区名称与认知。此外，大型公园、机场、公墓及其他特殊区域等非居住区将在本数据集中单独呈现，并根据其类型分配代码（详见NTAType字段）。本数据集所有过往发布版本均可在<a href="https://www.nyc.gov/content/planning/pages/resources/datasets/neighborhood-tabulation">DCP官网：BYTES of the BIG APPLE</a>获取。当前版本：26b
