Methodology

Areas that can potentially be reached by motorized travel are created using the isochrone service of the openrouteservice. An isochrone basically represents an area that is reachable from location x in time y by means of transport z. Isochrones are based on principles of (road) network analysis. The interaction of facilities, road network, isochrones and population distribution is depicted in the figure below.

Isochrones are calculated for distinct time intervals of 10 minutes each, up to a maximum of 60 minutes. In addition, a further interval of greater than 60 minutes to the respective country border is created. For each interval, the respective population residing therein is added from WorldPop and then aggregated to different scales.

For the aggregation geoboundaries administrative geodata is used.

Caveats / Comments

The underlying routing profile assumes car travel. in many countries this does not reflect the majority and must be considered as a best case scenario.

Therefore, the exact estimates should be taken with caution and interpreted in comparative relation to each other.

Furthermore, the degree of uncertainty of the data sets used is unknown:

  • Completeness of the road network

  • Thematic accuracy and completeness of healthcare facilities

  • Accuracy of population distribution. Especially in remote areas.
