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.
To provide high spatial resolution subnational estimates of poverty and inequality for use by a wide user community for interdisciplinary studies of poverty, inequality and the environment.

贫困测绘项目：贫困与不平等小区域估计数据集收录了非洲、亚洲、欧洲、北美及南美约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。此类指标以国家为单位，结合人口普查与调查数据，通过小区域估计（Small Area Estimates）技术推导得出。本数据集的全部数据均由原始数据提供方整合、标准化处理，最终形成统一的空间参考型全球一致数据集。数据集产品包含形状文件（矢量数据）、表格数据集（CSV格式）以及质心点数据（包含地理单元经纬度与对应贫困估计值的CSV格式文件）。此外，本数据集还附带XLS格式的数据目录，其中包含详细的数据集信息与说明文档。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。
本数据集旨在提供高空间分辨率的次国家级贫困与不平等估计结果，供广大用户群体开展贫困、不平等与环境相关的跨学科研究使用。
