2020 Neighborhood Tabulation Areas (NTAs) - Mapped

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年街区制表区域（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）数据的中等规模统计地理单元。2020年街区制表区域由2020年人口普查片区（census tracts）汇总而成，并嵌套于社区区划制表区域（Community District Tabulation Areas，CDTA）内部。街区制表区域的划定出于地理精准性与统计可靠性的双重需求。因此，每个街区制表区域均拥有足够的人口规模，可抵消美国社区调查相关的抽样误差，同时其分析单元规模小于社区区划制表区域。尽管街区制表区域的边界与关联名称大致契合纽约民众普遍认知的诸多街区，但街区制表区域并非旨在精准定义所有街区，也并非要穷尽纽约市所有街区的命名与认知范畴。此外，大型公园、机场、墓地及其他特殊区域等非住宅区域在本数据集中单独分类，并根据其类型赋予对应编码（详见NTAType字段）。本数据集所有过往发布版本均可通过<a href="https://www1.nyc.gov/site/planning/data-maps/open-data/bytes-archive.page?sorts[year]=0">BYTES of the BIG APPLE- Archive</a>获取。
