Google Earth Engine——美国人口普查局定期发布一个名为TIGER的地理数据库。这个表格包含了2010年人口普查的人口概况1的数值，按普查区汇总

The United States Census Bureau regularly releases a geodatabase named TIGER. This table contains the 2010 census Demographic Profile 1 values aggregated by census tract. Tract areas vary tremendously, but in urban areas are roughly equivalent to a neighborhood. There are about 74,000 polygon features covering the United States, the District of Columbia, Puerto Rico, and the ​​Island areas.​​

For full technical details on all TIGER 2010 products, see the ​​TIGER technical documentation.​​

Each tract also includes attributes with sums of the DP1 population measurements that intersect the boundary. The columns have the same name as the shortname column in the ​​DP1 lookup table.​​

美国人口普查局定期发布一个名为TIGER的地理数据库。这个表格包含了2010年人口普查的人口概况1的数值，按普查区汇总。区的面积差别很大，但在城市地区，大致相当于一个社区。有大约74,000个多边形特征，覆盖美国、哥伦比亚特区、波多黎各和岛屿地区。

关于所有TIGER 2010产品的全部技术细节，请参见TIGER技术文件。

每个区还包括与边界相交的DP1人口测量值之和的属性。这些列的名称与DP1查询表中的短名列相同。
