Map of healthcare facilities (in 2012)90 and the population density (in 2015)91 living more than 5 km from healthcare facilities. Areas and healthcare facilities are coloured according to the generation (2G to 4G) of the cellular network in range, where the range is calculated from cell tower location and the distance of the furthest measured signal92 within the Uganda national boundary93. The white circles around the health facilities indicate the 5-km-radius threshold. This figure is a remapping of publicly available data using the open source geographical information system application QGIS (https://www.qgis.org). We chose Uganda as an example country owing to the availability of the required data. We downloaded healthcare facility locations and ranges from http://maps.data.ug/layers/geonode%3Ahealth_centres_ubos_and_others_merged, cell tower location from https://opencellid.org/ (OpenCelliD Project is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License), and population data from http://www.worldpop.org.uk/data/summary/?doi=10.5258/SOTON/WP00283 (WorldPop datasets are available under the Creative Commons Attribution 4.0 International License). For details on how we generated this graph see Supplementary Information section B. Raw and intermediate data can be found in Supplementary Table 3 and at https://doi.org/10.5281/zenodo.1320937.
