Query: Estimating Food Consumption and Poverty Indices with Mobile Phone Data   Recent studies have shown the value of mobile phone data to tackle problems
related to economic development and humanitarian action. In this research, we
assess the suitability of indicators derived from mobile phone data as a proxy
for food security indicators. We compare the measures extracted from call
detail records and airtime credit purchases to the results of a nationwide
household survey conducted at the same time. Results show high correlations (>
.8) between mobile phone data derived indicators and several relevant food
security variables such as expenditure on food or vegetable consumption. This
correspondence suggests that, in the future, proxies derived from mobile phone
data could be used to provide valuable up-to-date operational information on
food security throughout low and middle income countries.
