该数据集提供了南非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，数据集利用旅行时间等时线——代表驾车在给定时间或距离内可到达区域的多边形。这些等时线与WorldPop人口数据（提供100米分辨率估计）叠加，从而计算从医院服务10到120分钟时间间隔内以及从学校5到50公里距离间隔内的人口。分析单位基于geoboundaries国家边界定义，并在可用时在更细的管理级别（ADM 1-4）汇总结果。数据结构包括：地区或国家名称、ISO3国家代码、管理单元的唯一标识符、国家代码、管理级别、服务类别（教育、医院或初级医疗）、范围类型（距离或时间）、范围（距离以米为单位，时间以秒为单位）、指定范围内的人口、学龄人口数量、学龄人口累计百分比、当前距离带新增的学龄人口、当前间隔新增学龄人口比例、总人口累计百分比、当前距离带新增人口、当前间隔人口占总人口比例。

This dataset provides insights into spatial accessibility to healthcare and education services across South Africa. 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 or country name, ISO3 country code, unique identifier for the administrative unit, country code, administrative level of the unit, service category (education, hospitals or primary_healthcare), range type (distance or time), range (distance in meters or time in seconds), population within the specified range, number of school-age individuals within the range, cumulative percentage of school-age population, incremental school-age population added in the current distance band, proportion of new school-age population in the current interval, cumulative percentage of total population, incremental population added in the current distance band, share of the total population represented by the current interval.
