Measuring Transnational Migration with Roaming Datasets

Abstract

Transnational population mobility can be defined as living and working in two or more countries. Transnational lifestyle is becoming more and more commonplace in various parts of the world thanks to the rising population mobility, changing labor market, opening borders, and developing information and communication technologies. Measuring, understanding, and the managing of such communities is complicated; we can see that traditional statistics and register-based data are not suitable to describe the transnational community. In this paper, we are proposing and testing a methodology for measuring the transnational mobility of a population with the help of the roaming databases of mobile network operators.
