Investigating the effect of clustering of the urban field on sustainable population growth of centrally located and peripheral towns.

In a previous study (Portnov and Erell, 1998a), an Index of Clustering was defined, which allowed an analysis of the combined effect of spatial isolation and remoteness of peripheral towns on the long-term patterns of their population growth. In the present paper, the analysis of the effect of clustering of the urban field on the patterns of population growth is extended to centrally located urban places, and the validity of this index is tested in two unevenly populated countries--Israel and Norway. In both countries, the effect of clustering of the urban field on the patterns of urban growth is twofold. In sparsely populated areas, the presence of neighboring towns appears to increase their chances of attracting potential migrants due to inter-urban exchanges, while in more densely populated areas, increasing clustering tends to reduce migration influx to a given locality due to inter-town competition. Following this conclusion, a strategy of "redirecting priorities" leading to the formation of urban clusters is proposed, which may enhance the potential of urban growth in geographical areas where this is desirable.

Urbanization and economic development policy in Korea.

"This paper has firstly discussed the development strategy and urbanization in [the Republic of] Korea for the period 1960-1980. [This is] followed with an intensive review of the past and recent population redistribution policy of Korea. Finally the authors make some general suggestions which are characterized as an expansion of opportunities and services in the underprivileged areas." (summary in CHI)

The temporal and spatial dynamics of income and population growth in Ohio, 1950-1990.

"This paper focuses on spatial variation of growth within a state. Using Ohio as a case study, two hypotheses are extracted from the literature. First, the theories of polarization and polarization reversal suggest that in the old industrial core the leading sector role of manufacturing has diminished in old manufacturing poles, and that income growth trends differ substantially between these old poles and new centres of development. Second, the theories of suburbanization and migration reversals suggest that population growth is contingent upon level of urbanization, and that the relationship has changed drastically between the pre-1970s, 1970s, and post-1970s periods."

[Simulation of possible developments in urbanization in the German Democratic Republic by the use of a multi-regional population model].

An attempt is made to forecast likely trends in urbanization in the German Democratic Republic over the next 50 years using the multi-regional approach developed at the International Institute for Applied Systems Analysis in Laxenburg, Austria. "Three scenarios describe possible variants in the changes of fertility, mortality and interregional migration as demographic factors. The term 'region' is applied to 4 sizes of communities each grouped as rural communities, small towns, small medium-size towns, and large medium-size towns/large towns. The results of the simulation indicate for all three scenarios an absolute and relative decline in population of the rural communities and a continuation of the process of concentration among the population."

Polycentrism, commuting, and residential location in the San Francisco Bay area.

"The San Francisco Bay Area has taken on a distinct polycentric metropolitan form, with three tiers of hierarchical employment centers encircling downtown San Francisco.... In this paper it is found that polycentric development is associated with differentials in suburban and urban commute trip times: commute trips made by employees of suburban centers are shorter in duration than commute trips made by their counterparts in larger and denser urban centers. Differentials were even greater, however, with respect to commuting modal splits. Lower density, outlying employment centers averaged far higher rates of drive-alone automobile commuting and insignificant levels of transit commuting....The effects of housing availability and prices on the residential locational choices of those working both in urban and in suburban employment centers are also investigated...."

Some demographic and economic aspects of Third World and First World urbanization and the economic implications thereof for South Africa.

"This paper analyses various demographic and economic features of the urbanization process that is taking place in Third World (developing) and First World (developed) countries. A comparison of some demographic and economic differences between contemporary Third World urbanization and First World urbanization at a comparable stage of development is made. The aim is to see what South African urbanization can learn from the comparison between Third and First World urbanization."
