On the move: migration, urbanization and development in Papua New Guinea.

"Migration and urbanization data from Papua New Guinea's first truly national census in 1980 are considered against a backdrop of spatial and social inequalities. Source and destination factors affecting migration flows and destinations are found to relate to population density, availability of rural wages, ease of access, destination wage-earning opportunities, historical linkages and present day developments. Short-distance migration differs from longer-distance migration; many migrants are short-term, and possibly circular, migrants. Migration and urbanization are considered part of the same process of developmental change." A section is included on earlier censuses and surveys, data reliability, and related problems.

Abortion services in the United States, 1987 and 1988.

A 1989 survey by The Alan Guttmacher Institute shows that 1.6 million abortions were performed in the United States in 1988, a number that has remained relatively unchanged since 1980. More than 98 percent of abortions in 1987-1988 were performed in metropolitan areas. Although 51 percent of metropolitan counties have no provider of abortion services, 93 percent of nonmetropolitan counties are without a provider. The lack of abortion services in nonmetropolitan areas has been intensified by a 13 percent reduction since 1985 in the number of hospitals that offer abortion services. The number of nonhospital facilities providing abortion services increased by four percent, however, and specialized clinics provided 64 percent of all abortions performed in 1988.

[Urbanization, the growth of big cities, and some of their problems].

The system of cities in developing countries (which usually are ex-colonial countries) is commonly characterized by primate city domination. The presence of big cities are often felt as parasitic, rather than being economically constructive. Rapid population growth in big cities is often accompanied by 1) shortages of productive employment opportunities, urban housing, and public services; and 2) emergence of squatter settlements, environmental pollution, and sociopsychological stress. In 1985, the urban population of Indonesia had reached 43 million, or 26.2% of the total population. So far, the growth of Indonesia's urban population is concentrated in its metropolitan cities. Even though the pattern of primacy is not striking, a tendency exists for the city-size distribution to deviate more from rank-size rule distribution. Distorted patterns of spatial development have restricted the development of small and middle range cities. In the year 2000, the urban population of Indonesia is estimated to become more than twice its number in 1985. Therefore, national urban policies need to focus more on promoting the development of intermediate and small cities.

[Intra-urban population and housing in Sao Paulo].

"This paper outlines an analysis of intra-urban demography in Sao Paulo [Brazil], by means of differentials among rates of population growth, densities and age distributions of the several spatial segments of the city. In trying to analyze together housing and demographic variables, it associates the youth of the peripheral population to the housing model prevalent till the eighties--irregular allotment, self-help and home ownership. The data show changes in this peripheral pattern for the last decade: the population growth rate of the central zone (mainly the interior ring) has been greater than that of the periphery. This would be explained by the increase of inner city slums and by verticalization. This tendency was already visible from census data of 1970 and 1980, which show an increase in the number of slums and in the proportion of tenants." (SUMMARY IN ENG)

The spatial pattern of urban population growth in Java, 1980-1990.

"The emergence of fast-growing peri-urban regions and corridors joining large cities has been a feature of rapid urban growth in Asia in the last fifty years. These areas have been characterised by a mixture of urban and rural activities and by strong rural-urban linkages. This paper uses data from the 1980 and 1990 Indonesian Censuses to measure the extent to which this process has been occurring on Java in the intervening decade. It calculates and categorises the absolute and proportional increase in the urban populations of each kabupaten in Java, and examines some of the reasons for the emerging patterns. The paper concludes with a discussion of the policy implications of the findings."

The long run effect of green belt amenities upon the population growth: the case of almost linear demand function.

"The purpose of this paper is to suggest that, in evaluating the relevance of sustaining the green belt, we must pay more attention to the fact that the green belt amenities can accelerate rather than decelerate the population growth of a city. For this, this paper analyzes the case where there exist green belt amenities and the demand for land function is almost linear. In this case, it can be shown that the green belt is ineffective in restricting the population growth in the long run."

[Development of urbanization in Japan].

"In Japan urbanisation has developed very rapidly in relation with economic development and concentration of the population and industry in towns; in consequence urbanisation is making rapid progress in the suburbs of large towns. The author emphasises some geographical aspects of urbanisation in Japan: urban growth, spatial urbanisation, transformation of the landscape, regional circulation of capitals and characteristics of urbanisation in Japan."
