Metropolitan population growth and distribution in the American South, 1970-1990.

"Southern Metropolitan Statistical Areas (MSA) are rated among the nation's leaders in [U.S.] population growth in recent decades. Growth and rankings of MSAs are examined using Pannell's (1974) method. A linear rank-size pattern of cities is revealed, with centers of greatest population growing larger while smaller centers follow with proportionally smaller population changes. A regression model provided some support for the contention that city sizes affect city growth rates. Additional factors in southern metropolitan growth and decline were considered. Introduction of a labor cost factor into the regression model provided moderate support in accounting for variation in MSA growth rates. Several MSAs grew at rates predicted by the regression model while others performed differently than expected. Explanations for variations are presented for selected MSAs."

Metropolitan population change in Russia and the Former Soviet Union, 1897-1997.

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...."

Recent trends in Sydney's population.

"In the summer 1990 issue of this journal the author published a...paper on Sydney's [Australia] population geography. The profile drawn in that paper was Sydney as of the mid-1980s. The aim of the present article is to provide readers with an up-date on that profile, examining the demographic evolution of the city over the past decade...." Aspects considered include population growth, internal patterns of population change, ethnic composition, health and age distribution.

[A brief outline of demographic development in Bulgaria].

The author reviews the major demographic trends of the twentieth century in Bulgaria. "The results from the analysis show that the demographic development of Bulgaria especially in the years after 1950 differs very little from the developed, urbanized and industrialized countries. The common features are: development towards [replacement] fertility, [lower mortality rates], zero natural growth [leading] to an increasing life expectancy at birth, [and] population ageing...."

Spatial demographic trends and patterns in the Warsaw urban region.

The relationship between the age and sex structure of the Warsaw urban region of Poland and the population dynamics of this area is analyzed. "The process of spatial population development in the Warsaw urban region is of a cyclical nature. Starting from 1948-1950, the changes in the proportions of the population increase between the core and the remaining parts of the region oscillated over time. These trends can be interpreted with reference to the basic components of population change--natural increase and net migration, as well as policy-related factors."

The structural correlates of metropolitan migration: 1970-1975.

This study is concerned with the debate over the supremacy of organizational versus environmental models for explaining population change within the context of metropolitan-nonmetropolitan turnaround migration. A sample of U.S. metropolitan areas is classified by a migration typology that considers sign changes or consistencies in rates of net migration between the 1960s and 1970s. "Four categories result and organizational, environmental and technological data are analyzed utilizing ridge regression with interaction terms to ascertain whether structural differences among migration categories exist." The study shows that organizational factors are more relevant for urban areas experiencing in-migration, and environmental factors are more relevant for those experiencing out-migration.

[Population development in Greater Santiago between 1970 and 1982: an analysis of district census results].

"An attempt is made in the light of an analysis of population changes occurring in several sub-districts of Greater Santiago in the period between the last population censuses of 1970 and 1982, based on small-area census units (distritos and communas) to draw attention to the effects on the spatial growth of the city resulting from changed conditions in the political and juridical sphere since the change of power in 1973." The effect of changes in government policy concerning the liberalization of the property market and the illegal occupation of land are noted. (summary in ENG)

Monitoring the metropolitanization process.

Alternative approaches have led to different interpretations of the metropolitanization process in the United States. We identify and illustrate several methods and procedures for monitoring metropolitan-nonmetropolitan population change using the 1950-1980 U.S. decennial censuses. Two basic approaches are compared: constant area approaches and component methods. In addition, we assess the effects of changing metropolitan definitions on metropolitan-nonmetropolitan growth. The results clearly reveal that the underlying mechanics of metropolitanization not only are complex but have changed substantially during the 1950-1980 period. We conclude with observations regarding the use of these procedures in future research.

Is nonmetropolitan America being repopulated? The evidence from Pennsylvania's minor civil divisions.

We analyze population change and net migration, by age and sex, from 1940 to 1970, for 1,834 Nonmetropolitan Pennsylvania Minor Civil Divisions (MCD's) classified by residence, population potential, socioeconomic status, and distance from metropolitan centers. Our analysis indicates, as expected, reconcentration of residents from both urban and remoter nonmetropolitan localities into exurban peripheries 25 to 35 miles for metropolitan centers. Since 1960, however, a "turnaround" appears in many truly rural tracts, which have been experiencing an influx or retention of persons 35 years of age and older. Statistical explanations are strongest for males in poor, isolated places, weakest for more accessible, socioeconomically advanced places and their female inhabitants. Throughout the study period and area, nonurban MCD's register more positively than the rural.

Recent nonmetropolitan population change in fifty-year perspective.

Post-1970 nonmetropolitan population shifts are examined by dividing nonmetropolitan counties into ten cohorts based on the duration and direction of consistent population change since 1920. Analysis indicates that the post-1970 gains reported by Beale are pervasive in nonmetropolitan America, occurring even in a majority of the counties that lost population consistently from 1920 to 1970. Growth was greatest in countries adjacent to metropolitan areas but was more than urban spillover effect. In a clear break with traditional patterns, net inmigration contributed significantly to overall population gain and was particularly strong among countries without an urban center. The rate of natural increase continued to slow in the post-1970 period, with natural decrease becoming common among countries with protracted histories of population decline.

Population movement and city-suburb redistribution: an analytic framework.

This paper introduces an analytic framework that can be used to assess the relationships between individual movement differentials and place characteristics, on the one hand, and aggregate mobility levels and city-suburb population change (in size or composition), on the other. Application of this framework using census data for individual metropolitan areas allows the analyst to decompose population changes due to net migration into contributing mobility streams and their component rates which are subject to unique community and individual influences. The paper provides both theoretical and empirical rationale for the framework, illustrates its use with 1970 census data, and discusses its implications for empirical research on city-suburb population redistribution.
