Book Description
The world's population has risen to more than 7 billion people, making issues such as food supply, energy resources, and water quality even more serious. Population Growth examines this major issue in ways that emphasize the causes and effects of population growth. In addition, it examines why some countries face the challenge of a young population, while other countries must maintain the quality of life for an aging population. Finally, Population Growth explores the importance of education and economic opportunities in meeting these important challenges.

Book Description
According to most scientists, Earth's atmosphere has warmed by about 1.4 degrees Fahrenheit in the past 100 years. The result has been melting glaciers, rising sea levels, and more extreme weather events. Some people say that current climate change is part of the natural cycle of changes on Earth. Many scientists, however, think that Earth's climate is changing because of increased greenhouse gases in the atmosphere. Climate Change examines how countries around the world are taking steps, such as conservation, to lessen the effects of climate change.

Book Description
Is rapid world population growth actually coming to an end? As population growth and its consequences have become front-page issues, projections of slowing growth from such institutions as the United Nations and the World Bank have been called into question. Beyond Six Billion asks what such projections really say, why they say it, whether they can be trusted, and whether they can be improved. The book includes analysis of how well past U.N. and World Bank projections have panned out, what errors have occurred, and why they have happened. Focusing on fertility as one key to accurate projections, the committee examines the transition from high, constant fertility to low fertility levels and discusses whether developing countries will eventually attain the very low levels of births now observed in the industrialized world. Other keys to accurate projections, predictions of lengthening life span and of the impact of international migration on specific countries, are also explored in detail. How good are our methods of population forecasting? How can we cope with the inevitable uncertainty? What population trends can we anticipate? Beyond Six Billion illuminates not only the forces that shape population growth but also the accuracy of the methods we use to quantify these forces and the uncertainty surrounding projections. The Committee on Population was established by the National Academy of Sciences (NAS) in 1983 to bring the knowledge and methods of the population sciences to bear on major issues of science and public policy. The committee's work includes both basic studies of fertility, health and mortality, and migration; and applied studies aimed at improving programs for the public health and welfare in the United States and in developing countries. The committee also fosters communication among researchers in different disciplines and countries and policy makers in government, international agencies, and private organizations. The work of the committee is made possible by funding from several government agencies and private foundations.

Book Description
The world population surpassed the seven billion mark in 2011, yet many women and couples still lack access to reproductive health services. These facts have profound implications for maternal and child health, environmental quality, and food security. Global Population and Reproductive Health provides an introduction to an important and timely public health topic. The text is unique in that it explores the inextricable link between population and reproductive health – a connection that is often overlooked – as well as their impact on global and local environmental issues. Students will come away with a clear understanding of the relationships among all these issues, and the vital need for integrated policies and international cooperation. Contents Include: 1. Overview 2. Measures and Theories 3. Health 4. Related Issues 5. Policies

Book Description
This book broadens and deepens understanding of a wide range of population-climate change linkages. Incorporating population dynamics into research, policymaking and advocacy around climate change is critical for understanding trajectory of global greenhouse gas emissions, for developing and implementing adaptation plans and thus for global and national efforts to curtail this threat. The papers in this volume provide a substantive and methodological guide to the current state of knowledge on issues such as population growth and size and emissions; population vulnerability and adaptation linked to health, gender disparities and children; migration and urbanization; and the data and analytical needs for the next stages of policy-relevant research.

Book Description
Globalization connects governments, cultures, and economies, making it easier for people to make, sell, and buy goods worldwide. It brings different people more easily into contact, but it can also disrupt traditional cultures. It helps create jobs in poor countries and allows businesses to make goods more cheaply. However, it can also widen the gap between rich and poor. Globalization explains how people are working to bring the positive effects of globalization to populations around the world.

Book Description
Population and Climate Change provides the first systematic in-depth treatment of links between two major themes of the 21st century: population growth (and associated demographic trends such as aging) and climate change. It is written by a multidisciplinary team of authors from the International Institute for Applied Systems Analysis who integrate both natural science and social science perspectives in a way that is comprehensible to members of both communities. The book will be of primary interest to researchers in the fields of climate change, demography, and economics. It will also be useful to policy-makers and NGOs dealing with issues of population dynamics and climate change, and to teachers and students in courses such as environmental studies, demography, climatology, economics, earth systems science, and international relations.

Book Description
The United Nations population estimates and projections form a comprehensive set of demographic data to assess population trends at the global, regional and national levels. They are used in the calculation of many of the key development indicators commonly used by the United Nations system, including for more than one third of the indicators used to monitor progress towards the achievement of the Sustainable Development Goals. The 2019 revision of the World Population Prospects is the twenty-sixth edition of the official United Nations population estimates and projections, which have been prepared since 1951 by the Population Division of the Department of Economic and Social Affairs. The 2019 revision presents population estimates from 1950 until the present for 235 countries or areas, which have been developed through country-specific analyses of historical demographic trends. It builds on previous revisions by incorporating additional results from the 2010 and 2020 rounds of national population censuses as well as information from vital registration and recent nationally representative household sample surveys. The 2019 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and country levels. These Highlights summarise key population trends described by the estimates and projections presented in World Population Prospects 2019.

Book Description
This book addresses nine relevant questions: Will population growth reduce the growth rate of per capita income because it reduces the per capita availability of exhaustible resources? How about for renewable resources? Will population growth aggravate degradation of the natural environment? Does more rapid growth reduce worker output and consumption? Do rapid growth and greater density lead to productivity gains through scale economies and thereby raise per capita income? Will rapid population growth reduce per capita levels of education and health? Will it increase inequality of income distribution? Is it an important source of labor problems and city population absorption? And, finally, do the economic effects of population growth justify government programs to reduce fertility that go beyond the provision of family planning services?
