Interurban migration and the dynamics of a system of cities: 1. The stochastic framework with an application to the French urban system.

"A stochastic framework for the modelling of interurban migration is presented. The model is an extension of a recently developed master-equation approach to interregional migration. The population dynamics of the French urban system, described by a set of 78 cities, is investigated within the period 1954-82. The importance of synergy effects (self-reinforcing collective effects) as well as socioeconomic macrovariables for the understanding of urban dynamics becomes obvious. A forecasting of urban dynamics...[up to the year 2002 confirms] this result and [gives] further insight into the nested structure of urban systems."

Urban vegetational change as an indicator of demographic trends in cities: the case of Detroit.

"In this study the author seeks to find whether changes in urban vegetation can be linked to urban social changes by using Detroit [Michigan] as a case study. Demographic trends in Detroit are analyzed in light of the increasing greenness in the city detected by recent satellite images. Robust relationships between greenness change and demographic factors associated with urban decay (population decline, an increase in poverty level, and an increase in vacant units) are found.... It is concluded that vegetation trends could be used as indicators of urban socioeconomic changes. A vegetation-based urban environmental quality index could therefore be developed to monitor physical and social changes in the cities."

Metropolitan concentration in developing countries.

"We examine the economic, political and cultural determinants of urban concentration in developing countries using a sample of 53 countries. We find that as countries develop, urban concentration, measured as the largest city's share of the population, at first increases and then decreases. We also find that foreign investment influences concentration in a similar way since foreign investors tend to locate in the main city at low levels of development but are willing to locate outside the center in more developed countries. Political and cultural factors such as lack of democracy, government instability and religiously and [ethnically] homogeneous populations all contribute to high levels of urban concentration. For many developing countries these non-economic factors have led to primate cities whose size far exceeds what would be justified by economic considerations." (SUMMARY IN FRE AND GER)

African urbanization: dependent linkages in a global economy.

"The colonial experience drastically altered the indigenous urban system in Africa, replacing it with a European-driven urban system designed to facilitate the extraction of resources. The urban system and the nature of ties with the colonial power allowed African integration into the world economy only in a dependent fashion. These dependent ties were deepened as the world economy became more globalized in the post-colonial period. The continent rapidly urbanized, with much of the population concentrating in primate cities. This urbanization was not accompanied by economic growth; as a result Africa will soon become a continent of large cities--with urban population they cannot physically and economically support."

The simulation of urban system dynamics in Atlantic Canada, 1951-1991.

"A dynamic urban model is used to study the post-war evolution of the Atlantic Canada urban system. The computer-based simulation model is calibrated for the period 1951-86 and then employed to predict the 1991 population of each CMA and CA within the system. The simulation results show that, to a large extent, the evolution of the system can be understood in terms of endogenous system dynamics rather than exogenous events. Specifically, competition among the cities of the region is a significant factor in the urban system evolution. The high degree of abstraction of the model means that data requirements for application are minimal, and the calibration procedure is relatively simple. The successful predictions show that the model can yield useful results in spite of its simplicity." (SUMMARY IN FRE)

Population movements to a growth-pole: the case of Hosur, Tamil Nadu.

This study examines the characteristics of population growth in Hosur, a small town in Tamil Nadu, India. "A special feature of the population in Hosur is the phenomenon of bachelors living together, mostly young men who have migrated from big cities. Commuting is not important in the mobility pattern of Hosur, less than ten per cent of employees in the industrial areas travelling daily from outside. Only one-third of the non-migrant labour force has access to the more attractive jobs in the modern factories, while short-term wage labour plays an important role in the labour structure of commuters. The demographic future of Hosur is not connected strongly with commuting patterns, but more with the spatial behaviour of the bachelors."

The development process and urbanisation in a newly organised state: a case study of Haryana.

"This paper examines the impact of emergence of Haryana [India] as a new state in 1966 on its development and concomitant urbanisation process. The analysis is based on data for individual towns for all the post-Independence censuses of 1951 to 1981. It was found that urban growth in the state was far more rapid during the post-1966 period than that during the pre-1966 phase. The spatial picture of urban growth also changed somewhat."
