Urbanization itself has punctuated economic development. The spatial distribution of economic activity, measured in terms of population, output and income, is concentrated. The patterns of such concentrations and their relationship to measured economic and demographic variables constitute some of the most intriguing phenomena in urban economics. They have important implications for the economic role and size distribution of cities, the efficiency of production in an economy, and overall economic growth. As Paul Bairoch's magisterial work (1988) has established, increasingly concentrated population densities have been closely linked since the dawn of history with the development of agriculture and transportation. Yet, as economies move from those of traditional societies to their modern stage, the role of the urban sector changes from merely providing services to leading in innovation and serving as engines of growth.", isbn="978-0-230-28082-3", doi="10.1057/9780230280823_33", url="https://doi.org/10.1057/9780230280823_33" }
