Poverty Mapping Project: Small Area Estimates of Poverty and Inequality

The Poverty Mapping Project: 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.贫困地图项目：贫困与不平等小区域估计数据集，涵盖非洲、亚洲、欧洲、北美洲及南美洲约二十个国家的地方行政单元。该数据集基于国家层面的数据，结合了人口普查和调查数据，运用小区域估计技术进行推导。数据集的编制、整合与标准化工作均从原始数据提供方完成，形成了统一的空间参照和全球一致性的数据集。数据产品包括形状文件（矢量数据）、表格数据集（csv格式）以及质心（包含地理单元的经纬度和相关的贫困估计的csv文件）。此外，还提供了一份包含详细信息和文档的数据目录（xls格式）。该数据集由哥伦比亚大学国际地球科学信息网络中心（CIESIN）与众多外部数据提供方合作制作。
