World population projections, 2020

The world's population, today numbering some 5.5 billion people, may approach 12 billion by the end of the next century. By the year 2020, 26 years from today, it will most likely have increased by about 2.5 billion to a total of 8 billion people, an increase of nearly 100 million a year. Over 93 percent of this growth will take place in the developing countries. Nygaard contends that two regions in particular merit attention. South Asia and Africa, where large percentages of the poor live today and where future food production is of concern, face substantial increases in their populations. India, Pakistan, and Bangladesh plus the continent of Africa will add another 1.5 billion people to the population roles.Population forecasting. ,Population Statistics. ,Population growth. ,Africa Economic conditions. ,Asia Economic conditions. ,Bangladesh. ,Pakistan. ,India. ,

Maternity waiting homes in Southern Lao PDR : the unique \u27silk home\u27

The concept of maternity waiting homes (MWH) has a long history spanning over 100 years. The research reported here was conducted in the Thateng District of Sekong Province in southern Lao People&rsquo;s Democratic Republic (PDR) to establish whether the MWH concept would be affordable, accessible, and most importantly acceptable, as a strategy to improve maternal outcomes in the remote communities of Thateng with a high proportion of the population from ethnic minority groups. The research suggested that there were major barriers to minority ethnic groups using existing maternal health services (reflected in very low usage of trained birth attendants and hospitals and clinics) in Thateng. Unless MWH are adapted to overcome these potential barriers, such initiatives will suffer the same fate as existing maternal facilities. Consequently, the Lao iteration of the concept, as operationalized in the Silk Homes project in southern Lao PDR is unique in combining maternal and infant health services with opportunities for micro credit and income generating activities and allowing non-harmful traditional practices to co-exist alongside modern medical protocols. These innovative approaches to the MWH concept address the major economic, social and cultural barriers to usage of safe birthing options in remote communities of southern Lao PDR.<br /

A new model for competition between many languages

Time evolutions of number of cities, population of cities, world population, and size distribution of present languages are studied in terms of a new model, where population of each city increases by a random rate and decreases by a random division. World population and size distribution of languages come out in good agreement with the available empirical data.Comment: 6 pages 5 figure

The World Bank's population lending and sector review

The objective of this paper is to review the historical experience of the Bank's lending and sector activities in the population field, and to evaluate the Bank's strengths and weaknesses in this field. Based on analysis of Bank documents, interviews and field visits, the review concludes that the Bank's overall performance in the population field has been commendable and its efforts to differentiate its activities in the various part of the world laudable. PHN's work in establishing policy dialogue with governments on population is identified as the area in which the Bank's impact has been greatest. The Bank has been particularly effective with development of policy in countries with new programs rather than in those with established programs. The Bank's ability to deal with high level policy issues and to establish inter-sectoral linkages is seen as strong and effective. The greatest weaknesses in Bank projects are identified as the lack of diversity in project format, the organizational structure through which projects are implemented and the manner in which projects are supervised.Health Monitoring&Evaluation,ICT Policy and Strategies,HIV AIDS,Health Economics&Finance,Agricultural Research

CAUSES AND CONSEQUENCES OF THE WORLD POPULATION EVOLUTION

This study intends to realize a critical debate on the content and the dynamics of the theoretical concepts connected to the world population growth, trying to explain the origin and sense of the expression demographic explosion and other expressions that completed, detailed or disproved this syntagm. The research is founded on the idea that the debate on the terminology used in present to define the demographic evolution, the presentation of the global and the differential components of the population increase, the main factors and evolutive scenarios of the world population, throw light correctly on the dimension of the phenomenon and represent a guide for the demographic present time. Based on these relevant aspects, the study leads to the idea that our planet is structured in two diverging worlds: a poor one, still in a demographic expansion and a rich one, in a demographic stagnation, even in a virtual decline.demographic explosion, overpopulation, regional disparities

The brain drain and the world distribution of income and population

This paper models the evolution of the world distribution of income and shows that while the distribution of income per capita across economies in the world will be stable in the long run, the world distribution of population may be divergent. The paper then uses this model to analyze the impact of the current trend towards predominantly skilled emigration from poor to rich countries on fertility, human capital formation, and growth, in both the sending and receiving countries. It shows that in the long run, brain drain migration patterns may increase world inequality as relatively poor countries grow large in terms of population. In the short run however, it is possible for world inequality to fall due to rises in GDP per capita in large developing economies with low skilled emigration rates
