Poverty Mapping Project: Small Area Estimates of Poverty and Inequality

The Small Area Estimates of Poverty and Inequality data set consists of consumption-based poverty, inequality and related measures for subnational administrative units in approximately twenty countries throughout Africa, Asia, Europe, North America, and South America. These measures are derived on a country-level basis from a combination of census and survey data using small area estimates techniques. The collection of data have been compiled, integrated and standardized from the original data providers into a unified spatially referenced and globally consistent data set. The data products include shapefiles (vector data), tabular data sets (csv format), and centroids (csv file with latitude and longitude of a geographic unit and associated poverty estimates). Additionally, a data catalog (xls format) containing detailed information and documentation is provided. This data set is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with a number of external data providers.贫困与不平等小区域估计数据集（Small Area Estimates of Poverty and Inequality）涵盖非洲、亚洲、欧洲、北美及南美共约20个国家的次国家级行政单元的基于消费的贫困、不平等及相关测度指标。上述指标以国家为单位，结合普查与调查数据，采用小区域估计（Small Area Estimates）技术测算得到。本数据集从原始数据提供方采集、整合并标准化为统一的空间参考型全球一致化数据集。数据集产品包括矢量数据格式的形状文件（Shapefile）、CSV格式的表格数据集，以及包含地理单元经纬度与对应贫困估计值的质心点CSV文件。此外，本数据集还提供包含详细信息与说明文档的XLS格式数据目录。本数据集由哥伦比亚大学国际地球科学信息网络中心（CIESIN）联合多家外部数据提供方共同制作。
