Mobile-phone mapping succeeds where national censuses fail
The Washington Post - 10/30/2014
Traditionally, the way we know who lives where is the result of national censuses. But those head counts can be expensive and occur rarely, and a new study suggests that the the passive tallying that happens every time our mobile phones check into a cellphone tower can provide a sort of living census that, researchers say, can improve how we respond to everything from earthquake devastation to the spread of Ebola.
Pierre Deville of Belgium’s University of Louvain in Belgium and Northeastern University’s Center for Complex Network Research and Catherine Linard of Belgium’s Université Libre de Bruxelles are the study’s lead authors, and their newly released research appears in the Proceedings of the National Academy of Sciences.
