Predicting Poverty and Wealth with Mobile Phone Metadata

Project Info

Project Description

Accurate and timely estimates of population characteristics are a critical input to social and economic research and policy. In industrialized economies, novel sources of data are
enabling new approaches to demographic profiling, but in developing countries, fewer sources of big data exist.We show that an individual’s past history of mobile phone use can
be used to infer his or her socioeconomic status. Furthermore, we demonstrate that the predicted attributes of millions of individuals can, in turn, accurately reconstruct the
distribution of wealth of an entire nation or to infer the asset distribution of microregions composed of just a few households. In resource-constrained environments where censuses
and household surveys are rare, this approach creates an option for gathering localized and timely information at a fraction of the cost of traditional methods.
