摘要
城市 areas exist in a wide variety of 族群 sizes, from small towns to huge megacities. No proposed form for the 統計 distribution of city sizes has received more attention than Zipf’s law, a Pareto distribution with 冪次定律 exponent equal to one. However, this distribution is typically violated by empirical evidence for small and large cities. Moreover, no theory presently exists to derive city size distributions from fundamental demographic choices while also explaining consistent variations. Here we develop a comprehensive framework based on demography to show how the structure of migration flows between cities, together with the differential magnitude of their vital rates, determine a variety of city size distributions. This approach provides a powerful 數學 methodology for deriving Zipf’s law as
