Patterns of change in the intermetropolitan location of population, jobs, and housing: 1950 to 1980.

"This paper presents a discussion and estimates of a simultaneous-equations model of intrametropolitan location of population, employment, and housing. What distinguishes this work from prior research on suburbanization is that population is distinguished by income class, employment is distinguished by type, and housing is distinguished by mode (i.e., owner versus rental). The model is estimated for three distinct decades, namely, the 1950s, 1960s, and 1970s. Moreover, rather than inferring the causal linkages between population, employment, and housing from estimates of urban density functions or from relative changes in central city and suburban population, this paper utilizes [U.S.] data on actual movers between central cities (suburbs) and suburbs (central cities), as well as on the location of metropolitan in-migrants in the central city versus the suburban ring."

Changing urban populations: regional restructuring, racial polarization, and poverty concentration.

This study examines the changing profile of the urban United States, with particular reference to the impact of immigration, suburbanization, and growing diversity associated with increased racial and income polarization. "This overview provides a backdrop by focusing on the forces that shape key demographic trends across broad regions and in metropolitan areas and then shows how these trends have led to disparities in growth and decline, racial polarization, and poverty concentration."

Urbanization in the Republic of Korea and Taiwan: a NIEs pattern.

"This paper will present an analysis of urban structure in the Republic of Korea and Taiwan, which formed as these regions evolved into so-called ¿newly industrializing economies' (NIEs).... In Korea and Taiwan [the process of] over-urbanization and expansion of primate cities was already under way during the colonial period; but in the postwar process of rapid industrialization, their urban structures began to change again, giving rise to characteristics not observed in other developing countries. The first task of this paper is to analyze these characteristics in terms of a NIE.... The second task...is to undertake comparative analysis of the two types.... In Korea the rise of ¿regionalism' and the formation of an urban poor social stratum generated serious social conflict. Analyzing these problems is the third task of this paper."

Regional population redistribution in the USSR: 1979-84.

"The primary purpose of this paper is to assess very broadly the regional growth and redistribution of the total, urban and rural populations of the USSR, as well as aggregate, regional and city size patterns of urbanization for the 1979-84 period. In order to investigate the continuity or reversal of trends, comparisons with preceding intercensal periods will also be undertaken, particularly with the 1970-79 period." It is found that "regional rates of population change between 1979 and 1984 were generally lower than those of 1970-79, primarily due to a general decline in natural increase rates. In addition, regional variations in rates of population change for the 1979-84 period were similar to those of the 1970-79 period.... The USSR has apparently reversed its long-term trend of deconcentration in the sense that the population as a whole is becoming more concentrated again, but this time in a new area of concentration, Central Asia, which is now the most populous economic region."

Spatial distribution of total Hg in urban soils from an Atlantic coastal city (Aveiro, Portugal).

The aim of this study was to investigate the levels and the spatial distribution of total Hg concentrations in soils from the urban area of Aveiro (Portugal) in order to assess the impact of industrial activities and identified Hg emission sources in these urban soils. For this purpose, soils were collected in 25 sampling points (at two depths) within the urban perimeter and in places considered representative of the main green areas of the city. A median concentration of 0.091 mg kg(-1) (dry weight) was obtained, regardless the depth. Aveiro was considered a low polluted city in terms of total Hg and no direct effects of emissions of Hg from industrial activities nearby could be detected in these urban soils. Despite of the low values obtained, high variability (range of approximately 0.5 mg kg(-1)) was observed in the results. Such was considered to be related to characteristic features of soils in urban settings and to the behaviour of Hg in the urban environment.

Shifts in the distribution of rural population in the non-Chernozem zone of the RSFSR.

"Rural population change within the Non-Chernozem zone of the RSFRS [Russian Soviet Federated Socialist Republic] is examined over the period 1959-79 at several levels of analysis: the Non-Chernozem zone as a whole, its major economic regions, individual oblasts, individual rayons and individual farms and rural places. The overriding tendency at all levels of analysis has been the increasing spatial concentration of rural population." The authors observe that "this concentration assumes a variety of forms, from the concentration of rural population in the suburban zones of large cities and the immediate surroundings of rayon seats to a decline in the number of rural places (from 180,000 in 1959 to 118,000 in 1979) and the growth of local centers against a general background of rural population decline. The authors hint that the observed tendency is a positive development, in keeping with the policy of converting Soviet agriculture to a more intensive path of development."

The transformation of the agricultural population and the urbanisation process in China.

"Nine causes for the occurrence of surplus agricultural labour with the modernisation of agriculture have been identified. Several solutions to this problem are presented. Urbanisation of the agricultural population in a way suited to China's characteristics is necessary, important and possible." An example of labor saving through mechanization in Heilongjiang province is presented.
