Housing_Database_by_2020_Census_Tract

The NYC Department of City Planning’s (DCP) Housing Database Aggregate Tables provide the 2010 census count of housing units, the net change in Class A housing units since the census, and the count of units pending completion for commonly used political and statistical boundaries. These tables are aggregated from the DCP Housing Database, which is derived from Department of Buildings (DOB)-approved housing construction and demolition jobs filed or completed in NYC since January 1, 2010. Net housing unit change is calculated as the sum of all three construction job types that add or remove residential units: new buildings, major alterations, and demolitions, and can be used to determine the change in legal housing units across time and space.纽约市城市规划局（NYC Department of City Planning，简称DCP）的住房数据库汇总表，提供了2010年人口普查的住房单元总数、自该次普查以来A级住房单元（Class A housing units）的净变化量，以及适用于常用政治与统计边界的待完工住房单元数量。此类表格的数据汇总自DCP住房数据库，该数据库的数据源为2010年1月1日以来在纽约市提交或完成、经建筑局（Department of Buildings，简称DOB）审批的住房建设与拆除工程。净住房单元变化量的计算方式为三类可增减住宅单元的工程总和：新建建筑、重大改造及拆除工程，该指标可用于研判不同时空范围内合法住房单元的变化情况。
