The Bill and Melinda Gates foundation, interested in solving education or welfare related problems in developing countries, is looking for the solutions that could better gauge the demography of a country. Lack of any concrete census data from Afghanistan can be substituted by tracking migration patterns of people through Call Detail Records (CDR) from cellular subscribers.

We came up with a framework to visualize short-term movement over long distance and long-term migration patterns of people based on CDR, and to correlate these patterns. We track inter-provincial migration and how it is varies in response to Geopolitical events like Bomb-blasts, Flood, and Snowfall. CDR data is also supplemented with complementary data from airtime top up activity to account for socioeconomic factors of the subscriber.
