Statistics and Dynamics of Urban Populations

2023
Abstract In this book, we describe all aspects of quantitative approaches to urban population growth, ranging from measures and empirical results such as the famous Zipf law, to the mathematical description of their evolution. We will follow the historical development of these approaches, starting with the Gibrat law to modern stochastic

Modeling the Segregation of the Urban Population

Environment and Planning B: Planning and Design, 1984
The paper is concerned with the effects of spatial externalities on urban development. With the Herbert-Stevens model of the housing market as the point of departure, equilibrium conditions are formulated. Similar to those of stationary points in quadratic programming, these conditions allow the adaptation of the corresponding algorithms.
