From: A model for simulating emergent patterns of cities and roads on real-world landscapes

Population density distributions on a 6 km grid showing a typical Zipf’s Law relationship for the census data (red), and the LTP model (blue), which shows a comparably broad distribution. In contrast, a counterfactual ‘Geographical Determinism’ scenario (brown), with the same landscape conditions as ‘Water Bodies’, but lacking the reinforcement dynamics of the model, does not fit the census population data.
