The persistence of high fertility in sub-Saharan Africa, while all other world regions have been able to control population growth, represents a grave threat. Tradtional explanations for this phenomenon--e.g., lower levels of income, education, health, and urbanization--are not adequate, given the fact that many Asian countries have been able to reduce(More)
Searching for an optimum solution to the Bangladesh arsenic crisis: Thirty years ago Bangladesh experienced very high levels of infant and child mortality, much of it due to water-borne disease in deltaic conditions where surface water was highly polluted. In what appeared to be one of the great public health achievements, 95% of the population were(More)
This article aims to show how the period now known as adolescence came into being and how it was shaped by international economic, institutional, and social influences. It considers premodern societies and argues that traditional culture has shaped contemporary adolescence even more than has global society. Explanations are offered for the enormous(More)
Near-global fertility decline began in the 1960s, and from the 1980s an increasing number of European countries and some Asian ones achieved very low fertility (total fertility below 1.5) with little likelihood of completed cohort fertility reaching replacement level. Earlier theory aiming at explaining this phenomenon stressed the incompatibility between(More)
The confirmation of a significant number of HIV-positive persons and some deaths due to AIDS in Nigeria has rendered more urgent the study of sexual networking, both for an understanding of the risk of HIV transmission and also that of sexually transmitted diseases, which may serve as a vehicle for HIV infection. This article reports on a research project(More)
Abstract In the 39 years between the 1921 and 1960 censuses, urban population in Ghana multiplied by nine while the population of the whole country only trebled. The major factor in urban growth was rural-urban migration and the reproduction of the migrants. In 1963 a survey consisting of a systematic sample of households in 45 rural centres, randomly(More)
Summary Although sexual abstinence has probably been the single most important factor in restricting human fertility, Western researchers have tended to regard it as a phenomenon mostly found outside marriage. The research reported here was carried out amongst the Yoruba, a sub Saharan people, among whom it is more desirable in terms of social stability(More)
The present is unexpectedly a critical time for population change and policy. We are little more than half way through the great population growth spurt that began in the middle of the twentieth century, but developed-country governments seem to be losing interest in the issue. This loss of interest may have a significant demographic impact. The probable(More)
