The U.S. Department of Homeland Security (DHS) is responsible for securing and managing the nation's borders. Over the past decade, DHS has dramatically stepped up its enforcement efforts at the U.S.-Mexico border, increasing the number of U.S. Border patrol (USBP) agents, expanding the deployment of technological assets, and implementing a variety of "consequence programs" intended to deter illegal immigration. During this same period, there has also been a sharp decline in the number of unauthorized migrants apprehended at the border.
Trends in total apprehensions do not, ho
Climate change can reasonably be expected to increase the frequency and intensity of a variety of potentially disruptive environmental events--slowly at first, but then more quickly. It is prudent to expect to be surprised by the way in which these events may cascade, or have far-reaching effects. During the coming decade, certain climate-related events will produce consequences that exceed the capacity of the affected societies or global systems to manage; these may have global security implications. Although focused on events outside the United States, Climate and Social Stress: Impli[more]
The United States is in the midst of a major demographic shift. In the coming decades, people aged 65 and over will make up an increasingly large percentage of the population: The ratio of people aged 65+ to people aged 20-64 will rise by 80%. This shift is happening for two reasons: people are living longer, and many couples are choosing to have fewer children and to have those children somewhat later in life. The resulting demographic shift will present the nation with economic challenges, both to absorb the costs and to leverage the benefits of an aging population.

The population of Asia is growing both larger and older. Demographically the most important continent on the world, Asia's population, currently estimated to be 4.2 billion, is expected to increase to about 5.9 billion by 2050. Rapid declines in fertility, together with rising life expectancy, are altering the age structure of the population so that in 2050, for the first time in history, there will be roughly as many people in Asia over the age of 65 as under the age of 15.
It is against this backdrop that the Division of Behavioral and Social Research at the U.S. National Institute
Sponsored by the Census Bureau and charged to evaluate the 2010 U.S. census with an eye toward suggesting research and development for the 2020 census, the Panel to Review the 2010 Census uses this first interim report to suggest general priorities for 2020 research. Although the Census Bureau has taken some useful organizational and administrative steps to prepare for 2020, the panel offers three core recommendations, and suggests the Census Bureau take and assertive, aggressive approach to 2020 planning rather than casting possibilities purely as hypothetical.
The first recommendat
The census coverage measurement programs have historically addressed three primary objectives: (1) to inform users about the quality of the census counts; (2) to help identify sources of error to improve census taking, and (3) to provide alternative counts based on information from the coverage measurement program.
In planning the 1990 and 2000 censuses, the main objective was to produce alternative counts based on the measurement of net coverage error. For the 2010 census coverage measurement program, the Census Bureau will deemphasize that goal, and is instead planning to focus on
In June 2006, seventeen scientists and educators selected by the National Academies, the Academy of Sciences of Iran, and the Académie des Sciences of France held a workshop at the estate of the Fondation des Treilles in Toutour, France, to discuss issues concerning the role of science in the development of modern societies.
Science and Technology and the Future Development of Societies includes the presentations made at the workshop and summarizes the discussions that followed the presentations. Topics of the workshop included science and society issues, the role of science a
Over the past five years, business and education groups have issued a series of reports indicating that the skill demands of work are rising, due to rapid technological change and increasing global competition. Researchers have begun to study changing workplace skill demands. Some economists have found that technological change is "skill-biased," increasing demand for highly skilled workers and contributing to the growing gap in wages between college-educated workers and those with less education. However, other studies of workplace skill demands have reached different conclusions. These di
Serving as a companion to Growing Up Global, this book from the National Research Council explores how the transition to adulthood is changing in developing countries in light of globalization and what the implications of these changes might be for those responsible for designing youth policies and programs. Presenting a detailed series of studies, this volume both complements its precursor and makes for a useful contribution in its own right. It should be of significant interest to scholars, leaders of civil society, and those charged with designing youth policies and programs.
