NYC_Public_Use_Microdata_Areas_PUMAs_2010

The 2010 NYC Public Use Microdata Areas (PUMAs) are statistical geographic areas defined for the dissemination of Public Use Microdata Sample (PUMS) data. PUMAs have a minimum population of 100,000, are aggregated from census tracts, and approximate Community Districts (CDs), or combinations of CDs (There are 59 CDs and only 55 NYC PUMAs because of such combinations). This geography is also used for disseminating American Community Survey (ACS) estimates. These boundary files are derived from the US Census Bureau's TIGER project and have been geographically modified to fit the New York City base map.2010年纽约市公共使用微数据区域（Public Use Microdata Areas，简称PUMAs）是为发布公共使用微数据样本（Public Use Microdata Sample，简称PUMS）数据而划定的统计地理分区。PUMAs的人口下限为10万人，由人口普查片区聚合而成，其范围近似于社区专区（Community Districts，简称CDs）或多个CDs的组合（纽约市共设有59个CDs，但因存在组合情况，仅划定了55个PUMAs）。该地理分区同样用于发布美国社区调查（American Community Survey，简称ACS）的估算数据。此类边界文件源自美国人口普查局的TIGER项目，并已针对纽约市底图完成地理适配调整。
