Metropolis or region: on the development and structure of London.

"Drawing on a disparate range of sources and viewing the question from several perspectives, an attempt is made to trace the development of London over the period since 1800. An account of the physical expansion and population growth is outlined, with ¿London' defined at a number of distinct scales. Attention is first focused on London as a metropolis, and various modelling techniques are used to illustrate the nature of metropolitan expansion. Consideration is given to the possibility that the changing spatial distribution of population through migration may be likened to a well-known process in physics. This is followed by an analysis of London at the broader scale of a region, with similar modelling techniques being employed. Finally, the question is raised as to whether London can still be meaningfully viewed as a metropolitan entity or whether a regional perspective is now more appropriate." (SUMMARY IN FRE AND GER)

On the homogeneous structure found in the system of the population of cities in Japan.

The author applies Auerbach and Zipf's rank-size rule for the population of cities to data for the nine regions of Japan for 1960, 1965, 1970, and 1975. The rule is successfully applied, and the author concludes that "the system of population of cities in Japan was so homogeneous that the distribution of the population in cities in each of the regions of this country could be described by this same rank-size rule." Some theoretical considerations concerning the rank-size rule are also discussed. (summary in JPN)

Lifetime migration to the major cities of the United States, Asia, and Africa.

"The purpose of this paper is to compare and contrast the lifetime migration patterns into the major cities of selected developed and developing countries. This study was confined to cities in...the United States and certain Asian and African countries with relevant published data.... This paper has shown that some lifetime population movements were exceptionally high. Two-thirds of the residents of the major U.S. cities in 1970 were born elsewhere. The major cities in sub-Saharan Africa were second highest with 60 percent. Asian cities followed with 48 percent of their residents being lifetime migrants and the cities of North Africa were lowest with less than a third. Finally, the native population born and reared in most urban agglomerations will probably comprise a larger percentage of the total population in those areas in the future." (SUMMARY IN FRE AND ITA)

Teenage conception and contraception in the English regions.

Nationally available data on teenage fertility, family planning care and mortality were analysed to determine the relationship between teenage conception, availability of abortion and family planning care, and an indicator of socioeconomic disadvantage--the Standardized Mortality Ratio (SMR). In the 14 regions of England the strongest correlate of teenage conception and of the proportion of teenage conceptions aborted was female all-causes SMR. High levels of provision of NHS abortion services and uptake of family planning clinic care did not significantly reduce teenage fertility. Provision of traditional family planning services obviously plays an important role in preventing teenage pregnancy, but innovation in this service coupled with a concerted effort to reduce social disadvantage might have a greater impact on teenage fertility in England.

Segregation and diversity measures in population distribution.

"The purposes of the present paper are to show the relationship between measures of population diversity and measures of segregation, to describe the salient properties of these indexes, and to demonstrate the empirical interrelationships among them." Some measures not frequently used in population studies are considered, and empirical illustrations are given of the significance of using one measure rather than another. In particular, the author stresses proportional reduction of error interpretations for an index and considers its ability to handle more than two groups. The primary geographic focus is on the United States. The "introductory section of the paper treats conceptual issues in more detail. The second section reviews selected measures and recent critical viewpoints, while the third section tests their empirical performance. The conclusion makes some recommendations about the selection of an index. A detailed bibliography follows."

Settlement network development policy and urbanisation in Hungary in the 20th century.

"The paper brings out the role of political economy in influencing the process of urbanisation and [the] structure of settlement network. This is demonstrated through an empirical study of Hungary during the twentieth century. Three phases get easily distinguished: pre-1949 or the period of changes in the state boundaries; 1949-89 or the period of state socialism; and post-1989 or the period of institutional reform. An interesting finding is that there was a bias in favour of large cities and county seats in allocation of development funds under all the regimes."
