USAID DHS Spatial Data Repository

This collection consists of geospatial data layers and summary data at the country and country sub-division levels that are part of USAID's Demographic Health Survey Spatial Data Repository. This collection includes geographically-linked health and demographic data from the DHS Program and the U.S. Census Bureau for mapping in a geographic information system (GIS). The data includes indicators related to: fertility, family planning, maternal and child health, gender, HIV/AIDS, literacy, malaria, nutrition, and sanitation. <br><br>Each set of files is associated with a specific health survey for a given year for over 90 different countries that were part of the following surveys:<br>Demographic Health Survey (DHS)Malaria Indicator Survey (MIS)Service Provisions Assessment (SPA)Other qualitative surveys (OTH)Individual files are named with identifiers that indicate: country,
survey year, survey, and in some cases the name of a variable or
indicator. A list of the two-letter country codes is included in a CSV
file.<br>Datasets are subdivided into the following folders:<br>Survey boundaries: polygon shapefiles of administrative subdivision boundaries for countries used in specific surveys. Indicator data: polygon shapefiles and geodatabases of countries and subdivisions with 25 of the most common health indicators collected in the DHS. Estimates generated from survey data.<br>Modeled surfaces: geospatial raster files that represent gridded population and health indicators generated from survey data, for several countries.Geospatial covariates: CSV files that link survey cluster locations to ancillary data (known as covariates) that contain data on topics including population, climate, and environmental factors.Population estimates: spreadsheets and polygon shapefiles for countries and subdivisions with 5-year age/sex group population estimates and projections for 2000-2020 from the US Census Bureau, for designated countries in the PEPFAR program.Workshop materials: a tutorial with sample data for learning how to map health data using DHS SDR datasets with QGIS. Documentation that is specific to each dataset is included in the subfolders, and a methodological summary for all of the datasets is included in the root folder as an HTML file. File-level metadata is available for most files. <br><br>Countries for which data included in the repository include:<br>

本数据集集合包含美国国际开发署（United States Agency for International Development, USAID）的人口与健康调查空间数据仓库（Demographic Health Survey Spatial Data Repository, DHS SDR）所涵盖的国家及国家次级行政区划级别地理空间数据图层与汇总数据。本集合收录来自人口与健康调查项目（Demographic Health Survey, DHS）及美国人口普查局（U.S. Census Bureau）的地理关联健康与人口统计数据，可用于地理信息系统（Geographic Information System, GIS）制图。该数据集涵盖以下相关指标：生育率、计划生育、母婴健康、性别平等、艾滋病病毒/艾滋病（HIV/AIDS）、识字率、疟疾、营养状况与环境卫生。

每套文件均对应90余个参与以下各类健康调查的国家在特定年份开展的专项健康调查：人口与健康调查（Demographic Health Survey, DHS）、疟疾指标调查（Malaria Indicator Survey, MIS）、服务提供评估（Service Provisions Assessment, SPA）及其他定性调查（Other Qualitative Surveys, OTH）。单个文件以标识符命名，可体现国家、调查年份、调查类型，部分文件还会包含变量或指标名称。逗号分隔值（Comma-Separated Values, CSV）文件中收录了两位字母国家代码列表。

数据集按以下文件夹分类存储：
- 调查边界（Survey boundaries）：包含对应专项调查所涉国家的行政区划边界多边形形状文件（polygon shapefiles）。
- 指标数据（Indicator data）：包含收录人口与健康调查项目（DHS）采集的25项最常用健康指标的国家及次级行政区划多边形形状文件与地理数据库（geodatabase），数据均由调查数据估算生成。
- 建模曲面（Modeled surfaces）：包含由多国调查数据生成的网格化人口与健康指标地理空间栅格文件（geospatial raster files）。
- 地理空间协变量（Geospatial covariates）：包含将调查集群位置与辅助数据（即协变量covariates）关联的CSV文件，辅助数据涵盖人口、气候与环境因素等主题。
- 人口估算（Population estimates）：包含美国人口普查局（U.S. Census Bureau）为总统艾滋病救济紧急计划（President's Emergency Plan for AIDS Relief, PEPFAR）指定国家生成的2000-2020年5年年龄/性别组人口估算与预测数据，涵盖对应国家及次级行政区划的电子表格与多边形形状文件。
- 培训资料（Workshop materials）：包含使用QGIS软件结合人口与健康调查空间数据仓库（DHS SDR）数据集开展健康数据制图的教程与示例数据。
