During the last 25 years, life expectancy at age 50 in the United States has been rising, but at a slower pace than in many other high-income countries, such as Japan and Australia. This difference is particularly notable given that the United States spends more on health care than any other nation. Concerned about this divergence, the National Institute on Aging asked the National Research Council to examine evidence on its possible causes. According to Explaining Divergent Levels of Longevity in High-Income Countries, the nation's history of heavy smoking is a major reason why lifespans in the United States fall short of those in many other high-income nations. Evidence suggests that current obesity levels play a substantial part as well. The book reports that lack of universal access to health care in the U.S. also has increased mortality and reduced life expectancy, though this is a less significant factor for those over age 65 because of Medicare access. For the main causes of death at older ages-cancer and cardiovascular disease-available indicators do not suggest that the U.S. health care system is failing to prevent deaths that would be averted elsewhere. In fact, cancer detection and survival appear to be better in the U.S. than in most other high-income nations, and survival rates following a heart attack also are favorable. Explaining Divergent Levels of Longevity in High-Income Countries identifies many gaps in research. For instance, while lung cancer deaths are a reliable marker of the damage from smoking, no clear-cut marker exists for obesity, physical inactivity, social integration, or other risks considered in this book. Moreover, evaluation of these risk factors is based on observational studies, which-unlike randomized controlled trials-are subject to many biases.
Hispanics and the Future of America presents details of the complex story of a population that varies in many dimensions, including national origin, immigration status, and generation. The papers in this volume draw on a wide variety of data sources to describe the contours of this population, from the perspectives of history, demography, geography, education, family, employment, economic well-being, health, and political engagement. They provide a rich source of information for researchers, policy makers, and others who want to better understand the fast-growing and diverse population that we call "Hispanic." The current period is a critical one for getting a better understanding of how Hispanics are being shaped by the U.S. experience. This will, in turn, affect the United States and the contours of the Hispanic future remain uncertain. The uncertainties include such issues as whether Hispanics, especially immigrants, improve their educational attainment and fluency in English and thereby improve their economic position; whether growing numbers of foreign-born Hispanics become citizens and achieve empowerment at the ballot box and through elected office; whether impending health problems are successfully averted; and whether Hispanics' geographic dispersal accelerates their spatial and social integration. The papers in this volume provide invaluable information to explore these issues.
Designed to protect the privacy of individual student test scores, grades, and other education records, the Family Educational Rights and Privacy Act (FERPA) of 1974 places limits the access of educational researches, and slows research not only in education but also in related fields, such as child welfare and health. Recent trends have converged to greatly increase the supply of data on student performance in public schools. Education policies now emphasize education standards and testing to measure progress toward those standards, as well as rigorous education research. At the same time, private firms and public agencies, including schools, have replaced most paper records with electronic data systems. Although these databases represent a rich source of longitudinal data, researchers' access to the individually identifiable data they contain is limited by the privacy protections of FERPA. To explore possibilities for data access and confidentiality in compliance with FERPA and with the Common Rule for the Protection of Human Subjects, the National Academies and the American Educational Research Association convened the Workshop on Protecting Student Records and Facilitating Education Research in April 2008.
