该数据集提供了马达加斯加医疗保健和教育服务空间可达性的深入见解。它使用免费开放工具（如openrouteservice）和开放数据源（主要是OpenStreetMap）创建。为评估教育和医疗服务的可达性，采用旅行时间等时线（表示汽车在给定时间或距离内可到达区域的多边形）与WorldPop人口数据（100米分辨率估计）叠加，计算医院服务10至120分钟时间间隔内和学校5至50公里距离间隔内的人口覆盖。分析单元基于geoboundaries国家边界定义，并在可用时汇总更细的行政级别（ADM 1-4）结果。数据结构包括行政单位名称、ISO国家代码、唯一标识符、服务类别（教育、医院或初级医疗保健）、范围类型（距离或时间）、范围值、总人口、学龄人口及相关比例指标等。该数据集是HeiGIT在HDX上众多导出数据之一，适用于公共健康、教育规划和地理空间分析领域。

This dataset provides insights into spatial accessibility to healthcare and education services across Madagascar. It has been created using free and open tools such as openrouteservice and open data sources, primarily OpenStreetMap (OSM). To assess accessibility to education and healthcare, we use travel-time isochrones—polygons representing areas reachable within a given time or distance by car. We overlay these isochrones with WorldPop population data, which provides 100m-resolution estimates. This allows us to calculate the population within time intervals from 10 to 120 minutes away from hospital services and distance intervals from 5 to 50 km away from schools. The unit of analysis is defined by geoboundaries country borders, and where available we also summarise results at finer administrative levels (ADM 1–4). Data structure includes region/country name, ISO codes, unique identifier, administrative level, service category (education, hospitals or primary_healthcare), range type (distance or time), range values, population counts, school-age population and related share metrics. This dataset is one of many HeiGIT exports on HDX, suitable for public health, education planning, and geospatial analysis applications.
