October 31, 2011, marked an uneasy milestone for Planet Earth. On this day, the global population surpassed seven billion. What does that mean for a world that, until the nineteenth century, was home to less than one billion people? Experts say it means the planet is in trouble. Some wonder if Earth will even be able to sustain human life at its current rate of growth. Will there be enough food for everyone? Will conflicts over land increase? How will the environment be affected? Can humanity survive the predicted disasters? More than a simple case of running out of space, the population crisis is interwoven with a host of other issues?from climate change and resource management to war, disease, and poverty. Discover how all these factors converge to place an entire planet in crisis mode?and explore what sort of responses that crisis may require.
How do you count a nation of more than 250 million peopleâ€"many of whom are on the move and some of whom may not want to be counted? How can you obtain accurate population information for apportioning the House of Representatives, allocating government resources, and characterizing who we are and how we live? This book attempts to answer these questions by reviewing the recent census operations and ongoing research and by offering detailed proposals for ways to improve the census.
A provocative description of the power of population change to create the conditions for societal transformation. As the world nears 8 billion people, the countries that have led the global order since World War II are becoming the most aged societies in human history. At the same time, the world’s poorest and least powerful countries are suffocating under an imbalance of population and resources. In 8 Billion and Counting, political demographer Jennifer D. Sciubba argues that the story of the twenty-first century is less a story about exponential population growth, as the previous century was, than it is a story about differential growth—marked by a stark divide between the world’s richest and poorest countries. Drawing from decades of research, policy experience, and teaching, Sciubba employs stories and statistics to explain how demographic trends, like age structure and ethnic composition, are crucial signposts for future violence and peace, repression and democracy, poverty and prosperity. Although we have a diverse global population, demographic trends often follow predictable patterns that can help professionals across the corporate, nonprofit, government, and military sectors understand the global strategic environment. Through the lenses of national security, global health, and economics, Sciubba demonstrates the pitfalls of taking population numbers at face value and extrapolating from there. Instead, she argues, we must look at the forces in a society that amplify demographic trends and the forces that dilute them, particularly political institutions, or the rules of the game. She shows that the most important skills in demographic analysis are naming and being aware of your preferences, rethinking assumptions, and asking the right questions. Provocative and engrossing, 8 Billion and Counting is required reading for business leaders, policy makers, and anyone eager to anticipate political, economic, and social risks and opportunities. A deeper understanding of fertility, mortality, and migration promises to point toward the investments we need to make today to shape the future we want tomorrow.
There have always been homeless people in the United States, but their plight has only recently stirred widespread public reaction and concern. Part of this new recognition stems from the problem's prevalence: the number of homeless individuals, while hard to pin down exactly, is rising. In light of this, Congress asked the Institute of Medicine to find out whether existing health care programs were ignoring the homeless or delivering care to them inefficiently. This book is the report prepared by a committee of experts who examined these problems through visits to city slums and impoverished rural areas, and through an analysis of papers written by leading scholars in the field.
By telling how the US census classified and divided Americans by race and origin from the founding of the United States to World War II, this text shows how public statistics have been used to create an unequal representation of the nation
Chronic homelessness is a highly complex social problem of national importance. The problem has elicited a variety of societal and public policy responses over the years, concomitant with fluctuations in the economy and changes in the demographics of and attitudes toward poor and disenfranchised citizens. In recent decades, federal agencies, nonprofit organizations, and the philanthropic community have worked hard to develop and implement programs to solve the challenges of homelessness, and progress has been made. However, much more remains to be done. Importantly, the results of various efforts, and especially the efforts to reduce homelessness among veterans in recent years, have shown that the problem of homelessness can be successfully addressed. Although a number of programs have been developed to meet the needs of persons experiencing homelessness, this report focuses on one particular type of intervention: permanent supportive housing (PSH). Permanent Supportive Housing focuses on the impact of PSH on health care outcomes and its cost-effectiveness. The report also addresses policy and program barriers that affect the ability to bring the PSH and other housing models to scale to address housing and health care needs.
Thanks to modern medicine, people are living longer. But can our planet support such a large population? Experts weigh in on the subject, introducing readers to ideas and key details, including how populations grow, change, and how trends are measured. Take Action boxes suggest research activities students can do to increase their understanding of the issue.
