Carlos Sarraute, Pablo Blanc, Javier Burroni

TL;DR
This paper analyzes Mexican mobile phone usage to understand demographic patterns and introduces a new method to predict age and gender of users based on calling behavior and communication networks.
Contribution
It presents an observational study of usage differences by demographics and a novel methodology for demographic prediction using call patterns and communication graph structure.
Findings
Significant differences in phone usage across age and gender groups.
Effective demographic prediction achieved on a large real-world dataset.
Abstract
Mobile phone usage provides a wealth of information, which can be used to better understand the demographic structure of a population. In this paper we focus on the population of Mexican mobile phone users. Our first contribution is an observational study of mobile phone usage according to gender and age groups. We were able to detect significant differences in phone usage among different subgroups of the population. Our second contribution is to provide a novel methodology to predict demographic features (namely age and gender) of unlabeled users by leveraging individual calling patterns, as well as the structure of the communication graph. We provide details of the methodology and show experimental results on a real world dataset that involves millions of users.
