Abstract
We consider a network of mobile phone customers aggregated by
geographical proximity. We analyze the anonymous communication patterns of 2.5
million customers of a Belgian mobile phone operator. Grouping customers by billing
address, we build a social network of cities, that consists of communication between
571 cities in Belgium. We show that inter-city communication intensity is characterized
by a gravity model: the communication intensity between two cities is proportional to
the product of the size of the population of these cities divided by the square of their
distance.
