Gridded Population of the World, Version 4 (GPWv4): Administrative Unit Center Points with Population Estimates, Revision 11

The Gridded Population of the World, Version 4 (GPWv4): Administrative Unit Center Points with Population Estimates, Revision 11 consists of UN WPP-adjusted population estimates and densities for the years 2000, 2005, 2010, 2015 and 2020, as well as the basic demographic characteristics (age and sex) for the year 2010. The data set also includes administrative name, land and water area, and data context by administrative Unit center point (centroid) location. The center points are based on approximately 13.5 million input administrative Units used in GPWv4, therefore, these files require hardware and software that can read large amounts of data into memory.

《世界人口网格，版本 4（GPWv4）：行政单元中心点及人口估计，修订版 11》包含了联合国人口预测署（UN WPP）调整后的人口估计和密度数据，涉及年份为 2000、2005、2010、2015 和 2020 年，同时还包括了 2010 年的基本人口统计学特征（年龄和性别）。该数据集还涵盖了行政名称、陆地和水域面积，以及通过行政单元中心点（质心）位置的数据背景。中心点基于大约 1350 万个在 GPWv4 中使用的输入行政单元，因此，这些文件需要能够读取大量数据至内存的硬件和软件。
