该数据集提供了厄立特里亚全国范围内医疗和教育服务空间可达性的深入分析。它利用免费开放的工具（如openrouteservice）和开放数据源（主要是OpenStreetMap）创建。通过计算汽车旅行时间等时线（即给定时间或距离内可到达的区域多边形），并与WorldPop的100米分辨率人口数据叠加，评估了教育和医疗服务的可达性。具体来说，数据集计算了距离医院服务10到120分钟时间间隔内的人口，以及距离学校5到50公里距离间隔内的人口。分析单位基于geoboundaries的国家边界，并在可用时汇总了更细的行政级别（ADM 1-4）结果。数据结构包括地区名称、ISO国家代码、唯一标识符、行政级别、服务类别（教育、医院或初级医疗）、范围类型（距离或时间）、范围值（米或秒）、总人口、学龄人口、学龄人口比例、学龄人口区间增量及其比例、总人口比例、人口区间增量及其比例等变量。该数据集旨在支持公共健康、教育规划和地理信息科学等领域的研究和应用。

This dataset provides insights into spatial accessibility to healthcare and education services across Eritrea. 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, travel-time isochrones—polygons representing areas reachable within a given time or distance by car—are used. These isochrones are overlaid with WorldPop population data, which provides 100m-resolution estimates, allowing calculation of 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, results are summarized at finer administrative levels (ADM 1–4). The data structure includes variables such as region name, ISO country code, unique identifier, administrative level, service category (education, hospitals, or primary_healthcare), range type (distance or time), range value (in meters or seconds), total population, school-age population, school-age population share, incremental school-age population in distance bands, and corresponding shares for total population. This dataset supports research and applications in public health, education planning, and geographic information science.
