Population_Administrative_Level_0_Country_Level

Country Population (Admin0) using aggregated Facebook high resolution population density data (https://data.humdata.org/organization/facebook). The world population data sourced from Facebook Data for Good is some of the most accurate population density data in the world. The data is accumulated using highly accurate technology to identify buildings from satellite imagery and can be viewed at up to 30-meter resolution. This building data is combined with publicly available census data to create the most accurate population estimates. This data is used by a wide range of nonprofit and humanitarian organizations, for example, to examine trends in urbanization and climate migration or discover the impact of a natural disaster on a region. This can help to inform aid distribution to reach communities most in need. There is both country and region-specific data available. The data also includes demographic estimates in addition to the population density information. This population data can be accessed via the Humanitarian Data Exchange website.本数据集为基于聚合后的Facebook高分辨率人口密度数据（https://data.humdata.org/organization/facebook）构建的国家人口（行政0级）数据集。该源自Facebook数据向善计划（Facebook Data for Good）的全球人口数据，属于全球精度顶尖的人口密度数据集之一。该数据通过高精度卫星影像建筑物识别技术生成，最高分辨率可达30米。此类建筑物识别数据与公开可获取的人口普查数据相融合，可生成精度顶尖的人口估算结果。该数据集被广泛应用于各类非营利组织与人道主义机构的工作中，例如用于分析城市化进程与气候移民趋势，或是评估自然灾害对特定区域的影响，从而为援助物资分配提供决策依据，精准覆盖最亟需支持的社区群体。数据集同时涵盖国家层面与区域层面的细分数据，除人口密度信息外，还包含人口统计相关的估算数据。用户可通过人道主义数据交换（Humanitarian Data Exchange）平台获取该类人口数据。
