"In this paper we [propose] a new procedure for estimating population density functions under conditions that the exact location of the CBD [central business district] is unknown or uncertain. As such it can also be utilized as a method for identifying the location of the CBD....[We apply] this method to cross-sectional data from Tel-Aviv-Yafo [Israel] during 1961 through 1990...."
"The paper conceptualizes processes driving change in perimetropolitan regions then, using Sydney [Australia] as a case study, analyses population growth rates and internal migration patterns between 1981 and 1991. Next, a set of social and demographic variables derived from the 1986 Census is analysed to derive four key dimensions of socio-spatial structure, namely: disadvantage, rurality, socio-economic status and retirement."

"Urban growth rates are documented for the largest United States Metropolitan Statistical Areas for the periods 1965-70 and 1975-80. The spatial pattern associated with these growth rates tends to reinforce the sunbelt-frostbelt dichotomy, as the majority of cities with positive migration rates for both time periods are located outside of the heavily industrialized Northeast and Midwest regions of the country. Two and three-group discriminant analyses indicate that manufacturing activity, local tax rates, and spending on education, are particularly important discriminators between growing and declining cities."

The author "assesses metropolitan population trends in Russia and the FSU [Former Soviet Union] over the period 1897-1997, focusing on the most recent period 1970-1997. The paper also examines internal population shifts within metropolitan areas--defined as an area of over one million in population consisting of a central city plus other urban centers of over 15,000 [people] within a 50-mile radius. Metropolitan processes in Russia and the FSU are compared with those in other major world metropolitan areas...."
The role of migration in urban growth in Argentina is analyzed over the period 1951-1991. "Three cohorts or groups are considered, based on the population each agglomeration had in 1951: under 50,000 inhabitants, over 50,000 but smaller than Greater Buenos Aires and, finally, Greater Buenos Aires. Analysis of available data shows that trends in growth changed since 1970, with a lower negative migration balance in the first cohort, a definite, stronger growth of the second one and a slower growth of Greater Buenos Aires on account of a reduction in the migration balance. Variations in rhythm for the three cohorts are considered and compared to the overall development in the country." (SUMMARY IN ENG)

A spatial analysis of fertility around Mexico City reveals an "inverted U" pattern which appears, on the face of it, inconsistent with both conventional economic location analysis and a spatial diffusion process. A closer examination of the problem implies that economic variables, when integrated in a proper model, may account for the observed cross- sectional spatial pattern, whereas pure diffusion can not. Spatial diffusion, however, may be responsible at least in part for the observed fertility changes over time. The geographical patterns of fertility in 2 states neighboring Mexico City (Mexico and Hidalgo) are examined empirically. The interpretation of the nonmonotonic distance effect is that there are significant locational advantages to childbearing at medium distances that are not enjoyed at households location either very close or far away from the city.
