Bettencourt, L.M.A., Zünd, D. Demography and the emergence of universal patterns in urban systems. Nat Commun
Objective:
- Adopt the lens of evolutionary population dynamics to show the emergence and meaning of Zipf’ distribution as a neutral law, signaling the absence of selection
Case:
- US
Methodology:
- Population growth equation
Data Source
- Mobility and migration data
Findings:
- The structure of migration flows between cities, together with the differential magnitude of their vital rates, determinea variety of city size distributions using Zipf law.
