[Migration to and from sections of Rotterdam].

"The number of people that move to, from or within large cities is, in a relative sense, far greater than the corresponding figure for the other parts of the Netherlands. Big city mobility concerns mostly internal migration. The 1995 migration statistics on sections of Rotterdam show dissimilarities between the different sections of the city with respect to composition and intensity of population flows. This article focuses on the differences between two sections of Rotterdam." (SUMMARY IN ENG)

Urbanization and internal migration.

This is a survey of the U.N. Population Division's contributions to the study of urbanization and internal migration, related research, and publications. In order to review these contributions, the relevant U.N. publications are classified under five broad topics: "estimates and projections of urban, rural and city populations, including problems of data comparability and methods to measure internal migration; monitoring of trends in urbanization; estimates and analyses of migration as a component of urban and metropolitan growth; studies of demographic and socio-economic aspects of urbanization, and studies of demographic and socio-economic aspects of internal migration."

Adolescent women's contraceptive decision making.

A modified rational decision model incorporating salient events and social influences (particularly from sexual partners) is used to analyze adolescent women's consistent use of oral contraceptives (OCs) over a six-month period. Data are taken from a panel study of 308 clients of an inner-city family planning clinic. Expected OC use was computed for each subject on the basis of subjective expected utility (SEU) theory, and is found in multivariate analyses to be a significant predictor of actual OC use. In addition, variables representing baseline and follow-up partner influences, the salience of pregnancy for the subject, and positive side effects of OCs during the first months of use are found to predict OC use. Partner's support of OC use during follow-up and positive side effects of OCs are found to predict OC use among subjects for whom OC use was not the expected decision according to baseline SEU. Implications of the findings for models of adolescents' contraceptive behavior and for clinicians are discussed.

Fertility decline and differences in less-developed countries: an anthropological microstudy of some communities of West Bengal, India and Upper Khumbu, Nepal.

The role of socioeconomic and other cultural factors as determinants of fertility change has been widely discussed, with some scholars emphasising an inverse relation between socioeconomic development and fertility, others suggesting that no such relation necessarily exists, and yet others indicating that by using data from various sources it is possible to "prove" that a given country's crude birth rate has declined, remained unchanged or increased. Demographic data are presented on age-sex structure, completed and total fertility rates, and age specific fertility rates by age cohorts of women, from several small, anthropological population units of West Bengal, India and Upper Khumbu, Nepal, exposed to various physical and cultural environmental stresses. The data show that fertility has declined in most of the populations/subpopulations studied and that the decline may, deductively, be attributed to economic development via greater family planning practices.

Infant feeding practices in Bombay slums.

A study was conducted in two slum areas in a Bombay suburb covering a total population of 4879. One hundred and fifty-three mothers having children below two years were interviewed. Ninety six per cent infants below the age of 4 months received breast milk, though exclusive breastfeeding was practised only in 37% infants. Timely complementary feeding rate was only 0.48. Twenty three per cent of mothers used bottle for administration of supplementary food or water. Only 15.7% of mothers used commercial milk formula and 8.5% used commercial weaning food.

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 costs of urbanization: a case study of Pakistan.

"A methodology is developed for estimating the aggregate costs of urbanization in Pakistan for 1983-2003. These costs are then compared with the future investment resource pool, and are found to be larger than the total pool. Alternative policy solutions to alleviate the problem are explored. Although some capital-saving strategies (such as major public works programs in rural areas and labor-intensive employment policies) would be helpful, it will be impossible to avoid a substantial rise in the proportion of the urban population without services from about one quarter to about one half of the total. The paper concludes with suggestions for refining the methodology in future studies."

The growth of large cities in India, 1961-1971.

"The general characteristics and the growth 1961-1971 of class 1 cities (those with more than 100,000 population in 1971) in India are examined. An unexpected correlation shows that the larger cities are more specialized, and growing faster. A factor analysis reduces the original variables to apparently significant factors, but these fail to classify the individual cities convincingly. An alternative simple classification of cities in terms of growth rates and degree of specialization shows strong regional components, dividing India into an emerging system of dynamic interdependent cities, and areas of stagnation and lack of specialization."

Characteristics of condom use and associated problems: experience in Bangladesh.

Data from the 1983 Bangladesh Condom User Survey (BCUS) are analyzed for patterns of condom use and various problems directly influencing their effectiveness. The survey was undertaken to explain an apparent gap between reports of the number of condoms distributed in certain areas compared with prevalence of users as reported in contraceptive prevalence surveys. These data are analyzed from behavioral and management perspectives to identify various factors influencing utilization, with potential implications for understanding and improving family planning and AIDS/STD prevention service systems. Patterns of use are related to differences in source of supply through public, free or private-priced systems, differences in urban or semi-rural place of residence, and differences in perceptions of men or women. The problem with condom use most often identified by the respondents was breakage.

Population and employment density functions revisited: a spatial interaction approach.

"This article proposes a generalized urban spatial structure and transportation network, and adapts the Garin-Lowry model to simulate both population and service employment densities in this hypothetical, yet realistic, city. The model is solved numerically while varying exogenous factors such as the distance friction coefficients and the spatial distribution of basic employment.... The results are generalized by estimating, via regression analysis, density functions over a large sample of simulated density patterns, pointing to the critical importance of transportation costs and basic employment distribution, and providing a basis for further empirical studies."

Risk groups and risk areas.

The risk approach to health management usually relates to groups of people. An alternative method is to concentrate on the areas at risk, which may sometimes be more useful in decision-making.
