university of oxford’s malaria atlas project just published new research showing that 80.7 percent of the world's population live an hour or less from a city. (in the visualization above, "d" stands for "day" and "h" is for "hour.") the map takes into account transportation infrastructure across the globe. from nature:

...new data sources provided by open street map and google now capture transportation networks with unprecedented detail and precision. here we develop and validate a map that quantifies travel time to cities for 2015 at a spatial resolution of approximately one by one kilometre by integrating ten global-scale surfaces that characterize factors affecting human movement rates and 13,840 high-density urban centres within an established geospatial-modelling framework.

our results highlight disparities in accessibility relative to wealth as 50.9% of individuals living in low-income settings (concentrated in sub-saharan africa) reside within an hour of a city compared to 90.7% of individuals in high-income settings. by further triangulating this map against socioeconomic datasets, we demonstrate how access to urban centres stratifies the economic, educational, and health status of humanity.
