Accessibility to Healthcare

Access to healthcare is a measure of human well-being that is constrained by numerous geographically-varying factors, the most immediate of which is the time it takes individuals to travel to a properly equipped and adequately staffed healthcare facility. Under the leadership of Dr Daniel Weiss and building on earlier research into travel time to cities, we have characterized travel time to healthcare facilities in unprecedented detail. We produce global travel time maps with and without access to motorized transport, thus characterizing travel time to healthcare for populations distributed across the wealth spectrum.
