Compartmental voter model

Numerous models in opinion dynamics focus on the temporal dynamics within a single electoral unit (e.g. country). The empirical observations, on the other hand, are often made across multiple electoral units (e.g. polling stations) at a single point in time (e.g. elections). Aggregates of these observations, while quite useful in many applications, neglect the underlying heterogeneity in opinions. To address this issue we build a simple agent based model in which all agents have fixed opinions, but are able to change their electoral units. We demonstrate that this model is able to generate rank size distributions consistent with the empirical data.
