Access to electricity and digital inclusion: evidence from mobile call detail records

Abstract

Abstract Despite significant progress in mobile connectivity, a large number of individuals in Sub-Saharan Africa are at risk of being left behind, especially those living in rural areas and women. In this paper, we use an original data set of mobile call detail records from Senegal and exploit variations across plausibly similar rural municipalities to assess the impact of access to electricity on mobile connectivity. We find that access to mobile connectivity for rural users, measured by mobile telephony subscriptions or smartphone ownership, increases with access to electricity, with a stronger impact for women. The impact on usage is also positive, but stems from the increased volume of incoming communications: rural mobile users with access to electricity do not place more calls than those with limited access; rather, they receive more calls and text messages from urban areas, especially those with higher living standards. These findings suggest that access to electricity can be a significant driver of digital inclusion in Sub-Saharan Africa.
