Fig. 3 — National plots for all sub-Saharan African countries comparing relative accessibility coverage statistics at 30, 60, 90, 120, 150, and 180 min travel time for the six gridded population data sets. Each plot corresponds to the relative geographical location of the country. Legend indicates the total population falling on barriers (i.e., permanent waterbodies) and thus not included in the analysis.
