"Population-based survey experiments have become an invaluable tool for social scientists struggling to generalize laboratory-based results, and for survey researchers besieged by uncertainties about causality. Thanks to technological advances in recent years, experiments can now be administered to random samples of the population to which a theory applies. Yet until now, there was no self-contained resource for social scientists seeking a concise and accessible overview of this methodology, its strengths and weaknesses, and the unique challenges it poses for implementation and analysis. Drawing on examples from across the social sciences, this book covers everything you need to know to plan, implement, and analyze the results of population-based survey experiments. But it is more than just a 'how to' manual. This lively book challenges conventional wisdom about internal and external validity, showing why strong causal claims need not come at the expense of external validity, and how it is now possible to execute experiments remotely using large-scale population samples. Designed for social scientists across the disciplines, Population-Based Survey Experiments provides the first complete introduction to this methodology"--Provided by publisher4207 Population-based survey experiments have become an invaluable tool for social scientists struggling to generalize laboratory-based results, and for survey researchers besieged by uncertainties about causality.

Population: Analysis and Models presents a discussion of demographic analysis and models. This book has been translated from French to provide access to an integrated textbook aimed at the French equivalent of undergraduates. The book is organized into two parts. Part I is devoted to analysis and is subdivided into two sections. The first section deals with elementary analysis or the steps that must precede an analysis of any complexity. It comprises three chapters: after an introduction, it presents the analysis of the results of one census followed by a summary of the analysis of population

The approach of equilibrium has been greeted with forebodings of labour shortages and of inability to populate growth centres or develop resources; further large scale immigration has been recommended and it is claimed that Australia can accommodate many times its present population. These forebodings are challenged. The population structure will become more normal and the workforce will continue to grow, its skills depending upon training and rewards. Growth centres are an alternative to further expansion of capital cities and imply fewer at risk of poverty and less risk to the environment.

It is standard practice, both within and outside China, to divide its population between rural and urban. However, this distinction is more complex than at first appears. China's State Statistical Bureau uses three distinct concepts when defining China's rural population. These have been translated into "rural," "agricultural" and "countryside" definitions. A further complication is that the people included in each of these definitions has changed over time. As a result, data for China's rural population is ambiguous unless the user can determine which of the three definitions is being used and from which period.

The peoples of the Western Hemisphere are in a young stage of demographic evolution. Except for the populations of the United States and Canada, those of Latin America have still a large proportion (about 40 per cent) of children and very few (less than 5 per cent) old persons. They will enter the stage of population "aging" sometime in the near or distant future, depend ing on how soon the fertility rate will follow the now declining death rate. This will lead these populations to a "demographic maturity" by lessening their bur den of dependency and by increasing the productivity of their peoples.

AbstractImmigration has conditioned the peopling of Australia. This article examines the evolution of Australia's population as influenced by immigration, what the impacts of population change have been for the economy, society and environment and what options exist to influence this process. The desirable course of policy is examined. A central role for immigration and the enhancement of its management and of complementary policies in building a worthy future for Australians are proposed. The contribution of past economic analysis to understanding of these issues and to informing policy settings is discussed and work still required in analysis and policy is identified.

Bericht über Bevölkerungsverteilung und -wachstum in Sudan und über Pläne und Möglichkeiten des National Population Committee (NPC) angesichts der für die nächsten 20 Jahre erwarteten Verdoppelung der Bevölkerungszahl bei einem Wirtschaftswachstum von "minus 1 Prozent". (DÜI-Sdt)

Assume k(k≥ 2) independent populations π1, π2μk are given. The associated independent random variables Xi,(i= 1,2,…k) are Logistically distributed with unknown means μ1, μ2, μk and equal variances. The goal is to select that population which has the largest mean. The procedure is to select that population which yielded the maximal sample value. Let μ(1)≤μ(2)≤…≤μ(k) denote the ordered means. The probability of correct selection has been determined for the Least Favourable Configuration μ(1)=μ(2)==μ(k – 1)=μ(k)–δ where δ > 0. An exact formula for the probability of correct selection is given.

Ten years ago the United Nations sponsored the first conference of governments on global population. Held in Bucharest, the conference was spearheaded by the United States and planned as a rally in support of the notion that population was growing too rapidly around the world and that the right prescription was family planning. But Bucharest did not turn out as planned. Such developing giants as India and China questioned the cure, and the rallying cry became, rather, that development is the best contraceptive. The conferees produced a grandly-named World Population Plan of Action which, though it acknowledged the role of family planning and contraception, had more than one plan in its platform.
