NYC_Neighborhood_Tabulation_Areas_2020

Neighborhood Tabulation Areas (NTA) are medium-sized statistical geographies for reporting Decennial Census and American Community Survey (ACS). NTAs are created by aggregating census tracts and nest within Community District Tabulation Areas (CDTA). NTAs were created 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).社区制表区域（Neighborhood Tabulation Areas, NTA）是用于汇报十年一次人口普查与美国社区调查（American Community Survey, ACS）数据的中型统计地理单元。该区域由普查街区聚合而成，嵌套于社区分区制表区域（Community District Tabulation Areas, CDTA）之内。其设计初衷为兼顾地理特异性与统计可靠性，因此每个NTA均拥有足够规模的人口，既能削弱美国社区调查所关联的抽样误差，又能提供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NTA并非旨在精准代表社区，也未穷尽纽约市所有社区的命名与认知维度。此外，大型公园、机场、公墓及其他特殊区域等非居住区均在此数据集中单独归类，并依据其类型赋予对应编码（详见NTAType字段）。
