该数据集提供了尼日尔医疗和教育服务空间可及性的深入洞察。它使用免费开放工具（如openrouteservice）和开放数据源（主要是OpenStreetMap）创建。为了评估教育和医疗的可及性，数据集采用旅行时间等时线（即表示在给定时间或距离内可通过汽车到达区域的多边形），并将其与WorldPop人口数据（提供100米分辨率估计）叠加。这样可以计算距离医院服务10到120分钟时间间隔内以及距离学校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，并在可用时在更细的行政级别（ADM 1-4）上汇总结果。数据结构包括区域或国家名称、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）、覆盖区方法（距离或时间）、范围（米或秒）、指定范围内的人口、学龄人口及其比例、人口份额等列。该数据集是HeiGIT在HDX上众多导出之一，旨在支持公共健康、人道主义和研究应用，但受限于OSM数据完整性、人口估计准确性、旅行时间假设和边界精度。This dataset provides insights into spatial accessibility to healthcare and education services across Niger. 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 columns such as name, iso, id, country, admin_level, category, range_type, range, population, school_age_population, school_age_population_share, school_age_population_interval, school_age_population_interval_share, population_share, population_interval, and population_interval_share. This dataset is one of many HeiGIT exports on HDX, intended for public health, humanitarian, and research applications, with limitations noted regarding OSM completeness, population estimates, travel time assumptions, and boundary precision.
