It is not news that each of us grows old. What is relatively new, however, is that the average age of the American population is increasing. More and better information is required to assess, plan for, and meet the needs of a graying population. The Aging Population in the Twenty-First Century examines social, economic, and demographic changes among the aged, as well as many health-related topics: health promotion and disease prevention; quality of life; health care system financing and use; and the quality of care--especially long-term care. Recommendations for increasing and improving the data available--as well as for ensuring timely access to them--are also included.

Tillfälligt slut
This book reviews the uses and abuses of microsimulation models--large, complex models that produce estimates of the effects on program costs and who would gain and who would lose from proposed changes in government policies ranging from health care to welfare to taxes. Volume 1 is designed to guide future investment in modeling and analysis capability on the part of government agencies that produce policy estimates. It will inform congressional and executive decision makers about the strengths and weaknesses of models and estimates and will interest social scientists in the potential of microsimulation techniques for basic and applied research as well as policy uses. The book concludes that a "second revolution" is needed to improve the quality of microsimulation and other policy analysis models and the estimates they produce, with a special emphasis on systematic validation of models and communication of validation results to decision makers.

America's international economic decisions rest to a large degree on the information available to policymakers. Yet the quality of international trade and financial data is in serious doubt. This book reveals how our systems for collecting and analyzing trade data have fallen behind the times--and presents recommendations for new approaches to accuracy and usefulness of these economic data. The volume traces the burgeoning use of international economic data by public and private analysts at a time when the United States is becoming increasingly integrated into the world economy. It also points out problems of capturing new transactions, comparing data from different sources, limited access to the data, and more. This is the first volume to review all three types of U.S. international data--merchandise trade, international services transactions, and capital flows. Highlights include: * Specific steps for U.S. agencies to take. * Special analyses on improving the accuracy of merchandise trade data, filling data gaps on the fast-growing international services transactions, and understanding structural changes in world capital markets.* Comments, complaints, and suggestions from an original survey of more than 100 key users of trade data. This practical volume will be invaluable to policymakers, government officials, business executives, economists, statisticians, and researchers.

The nation's health care system has changed dramatically and the country is debating further significant changes. Comprehensive information is needed to guide policymakers in understanding and evaluating the current problems and in formulating federal health care policy. This book contains an evaluation of the plan developed by the National Center for Health Statistics for restructuring its existing provider surveys. It identifies current and future data needed by researchers and policymakers to assess the effect of changes in financing, organization, and delivery of health care on access, quality, costs, and outcomes of care and determines the extent to which the design and content of the proposed survey can meet these data needs. The book goes beyond a simple review and recommends a design framework to develop a coordinated and integrated data system to gather information about people and their illness over time and to link this information to costs and health care outcomes.

The recent level of illegal immigration to the United States has increased debates about the effect of these immigrants on the cost of public services, and states have begun to enact policies that limit the public services available to illegal immigrants. The central issues are how many illegal immigrants reside in particular local areas and states and their effect on public expenditures and revenues and the economy in general. The Local Fiscal Effects of Illegal Immigration workshop selected six studies for analysis. The six case studies focused on one specific aspect of the complex question of the demographic, economic, and social effects of immigration: the net public services costs of illegal immigrants to selected geographical regions.

The Committee on National Statistics and the Committee on Population, at the request of the NIA, convened a workshop in March 1996 to discuss data on the aging population that address the emerging and important social, economic, and health conditions of the older population. The purposes of the workshop were to identify how the population at older ages in the next few decades will differ from the older population today, to understand the underlying causes of those changes, to anticipate future problems and policy issues, and to suggest future needs for data for research in these areas. The scope of the workshop was broader than that of the 1988 CNSTAT report, including not only data on health and long-term care, but also actuarial, economic, demographic, housing, and epidemiological data needs for informing public policy.

This report had its origin in a Committee on National Statistics workshop in November 1993, one of a series on improving economic statistics, jointly sponsored by the Bureau of Economic Analysis (BEA) and the Bureau of the Census of the U.S. Department of Commerce. The focus of the workshop was on revising the presentation of the government sector in the U.S. economic accounts to bring it more into line with the international System of National Accounts (SNA) and current data collection capability, to enhance information about the public sector, and to make the U.S. accounts more comparable to those of other countries.

The Social Security Administration (SSA) is reengineering its disability claims process for providing cash benefits and medical assistance to blind and disabled persons under the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) Program (Title II and Title XVI of the Social Security Act). As one element of this effort, SSA has proposed a redesigned disability determination process. The agency has undertaken a multi-year research effort to develop and test the feasibility, validity, reliability, and practicality of the redesigned disability determination process before making any decision about implementing it nationally. SSA requested the National Academy of Sciences to review and provide advice on its research relating to the development of a revised disability decision process, including the approach, survey design, and content of the Disability Evaluation Study (DES). One of the committee's tasks is to examine SSA's research into existing and other developing functional assessment instruments for the redesign efforts and to provide advice for adopting or developing instruments for the redesigned decision process and the DES.

The U.S. Department of Education uses estimates of school-age children in poverty to allocate federal funds under Title I of the Elementary and Secondary Education Act for education programs to aid disadvantaged children. Historically, the allocations have been made by a two-stage process: the department's role has been to allocate Title I funds to counties; the states have then distributed these funds to school districts. Until recently, the department has based the county allocations on the numbers and proportions of poor school-age children in each county from the most recent decennial census. States have used several different data sources, such as the decennial census and the National School Lunch Program, to distribute the department's county allocations to districts. In 1994 Congress authorized the Bureau of the Census to provide updated estimates of poor school-age children every 2 years, to begin in 1996 with estimates for counties and in 1998 with estimates for school districts.The Department of Education is to use the school district estimates to allocate Title I basic and concentration grants directly to districts for the 1999-2000 and later school years, unless the Secretaries of Education and Commerce determine that they are "inappropriate or unreliable" on the basis of a study by the National Research Council. That study is being carried out by the Committee on National Statistics' Panel on Estimates of Poverty for Small Geographic Areas.

This final report of the Panel on Alternative Census Methodologies provides an assessment of the Census Bureau's plans for the 2000 census as of the time of the 1998 census dress rehearsal. It examines changes in census plans following, and to a modest extent in reaction to, the panel's second interim report, regarding the use of sampling for nonresponse follow-up, construction of the master address file, use of multiple response modes and respondent-friendly questionnaires, and the use of administrative records. It also describes evaluation plans for the census dress rehearsal and plans for data collection and experimentation during the 2000 census. Most of the results from the dress rehearsal were not yet available to the panel, so this report does not offer any suggested changes to 2000 census plans in response to the dress rehearsal.

This report was prepared in response to a request from the Economic Research Service (ERS) of the U.S. Department of Agriculture (USDA). It summarizes the discussions at a February 1998 workshop convened by the Committee on National Statistics; the Board on Children, Youth, and Families; and the Food and Nutrition Board. The fiscal year 1998 (FY1998) appropriations bill for USDA gave ERS responsibility for all research and evaluation studies on USDA food assistance programs. The bill provided $18 million to fund these studies, an increase from $7 million in FY1997. ERS asked the Committee on National Statistics for assistance in identifying new areas of research and data collection and in further improving the evaluation studies of food assistance programs. By bringing together many who work on evaluation of food assistance programs, policy analysis, survey methods, nutrition, child nutrition and child development, outcome measurement, and state welfare programs, the issues presented and discussed at the workshop provided ERS with information that could be used to develop a framework for their research program.

For every weapons system being developed, the U.S. Department of Defense (DOD) must make a critical decision: Should the system go forward to full-scale production? The answer to that question may involve not only tens of billions of dollars but also the nation's security and military capabilities. In the milestone process used by DOD to answer the basic acquisition question, one component near the end of the process is operational testing, to determine if a system meets the requirements for effectiveness and suitability in realistic battlefield settings. Problems discovered at this stage can cause significant production delays and can necessitate costly system redesign. This book examines the milestone process, as well as the DOD's entire approach to testing and evaluating defense systems. It brings to the topic of defense acquisition the application of scientific statistical principles and practices.

The Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) of 1996 fundamentally changed the nation's social welfare system, replacing a federal entitlement program for low-income families, called Aid to Families with Dependent Children (AFDC), with state-administered block grants, the Temporary Assistance for Needy Families (TANF) program. PRWORA furthered a trend started earlier in the decade under so called "waiver" programs-state experiments with different types of AFDC rules-toward devolution of design and control of social welfare programs from the federal government to the states. The legislation imposed several new, major requirements on state use of federal welfare funds but otherwise freed states to reconfigure their programs as they want. The underlying goal of the legislation is to decrease dependence on welfare and increase the self-sufficiency of poor families in the United States.In summer 1998, the Office of the Assistant Secretary for Planning and Evaluation (ASPE) of the Department of Health and Human Services (DHHS) asked the Committee on National Statistics of the National Research Council to convene a Panel on Data and Methods for Measuring the Effects of Changes in Social Welfare Programs. The panel's overall charge is to study and make recommendations on the best strategies for evaluating the effects of PRWORA and other welfare reforms and to make recommendations on data needs for conducting useful evaluations. This interim report presents the panel's initial conclusions and recommendations. Given the short length of time the panel has been in existence, this report necessarily treats many issues in much less depth than they will be treated in the final report. The report has an immediate short-run goal of providing DHHS-ASPE with recommendations regarding some of its current projects, particularly those recently funded to study "welfare leavers"-former welfare recipients who have left the welfare rolls as part of the recent decline in welfare caseloads.

The Social Security Administration (SSA) has been engaged in a major effort to redesign the process for determining disability for cash benefits and medical assistance under its Social Security Disability Insurance (SSDI), Title II of the Social Security Act and the Supplemental Security Income (SSI), Title XVI of the Social Security Act. Because of the complexity and far-reaching impact of its efforts, SSA concluded that the redesign effort requires extensive research, testing, and validation, as well as further development of some of its components before national implementation. The effect of the new determination process on the number and characteristics of future beneficiaries also needs further study. The agency asked the National Academies to provide ongoing independent and unbiased review of, and recommendations on, its current and proposed research as it relates to the development of a revised disability decision process including the approach, survey design, and content of the complex multiyear Disability Evaluation Study (DES).The present report is the third in a series of short interim reports of the National Academies' Committee to Review the SSA's Disability Decision Process. This third interim report relates directly to one of the contract tasks-review of the design, approach, and content of the DES, as proposed by SSA's contractor for the survey, Westat, Inc. This report is limited to a brief review of the sample design (including that of the pilot study), instruments and procedures, and response rates goals developed by Westat and provided by SSA in June 1999 to the committee for its review and recommendations. It also comments on the proposed timeline for initiation of each phase of the survey.

One of the most substantial policy changes in the past decade was the elimination of the main social welfare program for poor families, Aid to Families with Dependent Children, ending the entitlement to cash benefits and replacing it with a policy emphasizing work. A question relevant for understanding the consequences of this policy change is how the time allocation among work and family care activities of poor families has changed. President Clinton's proposed budget for fiscal 2001 includes funds for the Bureau of Labor Statistics (BLS) to develop a survey to measure how Americans spend their time (U.S. Department of Labor, 2000). BLS has already explored the feasibility of such a survey. In 1997, a pilot study that collected time-use data for a sample of Americans was conducted, and the results of that study were presented at a 1997 conference sponsored by BLS and the MacArthur Network on the Family and the Economy. Using knowledge gained from the pilot study and the conference, BLS published a report on the feasibility of a national time-use survey and developed a proposal to conduct the survey.Time-Use Measurement and Research is a summary of a workshop convened to consider data and methodological issues in measuring time use. This report discusses why time-use data are needed, highlighting many of policy and behavioral applications of time-use data. It also summarizes conceptual issues covered during the workshop, discusses a framework for how individuals and households allocate their time, and comments on some conceptual issues in measuring time use.

Part of an in-depth study of how information technology research and development could more effectively support advances in the use of information technology (IT) in government, Summary of a Workshop on Information Technology Research for Federal Statistics explores IT research opportunities of relevance to the collection, analysis, and dissemination of federal statistics. On February 9 and 10, 1999, participants from a number of communities - IT research, IT research management, federal statistics, and academic statistics - met to identify ways to foster interaction among computing and communications researchers, federal managers, and professionals in specific domains that could lead to collaborative research efforts. By establishing research links between these communities and creating collaborative mechanisms aimed at meeting relevant requirements, this workshop promoted thinking in the computing and communications research community and throughout government about possibilities for advances in technology that will support a variety of digital initiatives by the government.

Recent trends in federal policies for social and economic programs have increased the demand for timely, accurate estimates of income and poverty for states, counties, and even smaller areas. Every year more than $130 billion in federal funds is allocated to states and localities through formulas that use such estimates. These funds support a wide range of programs that include child care, community development, education, job training, nutrition, and public health. A new program of the U.S. Census Bureau is now providing more timely estimates for these programs than those from the decennial census, which have been used for many years. These new estimates are being used to allocate more than $7 billion annually to school districts, through the Title I program that supports educationally disadvantaged children. But are these estimates as accurate as possible given the available data? How can the statistical models and data that are used to develop the estimates be improved? What should policy makers consider in selecting particular estimates?This new book from the National Research Council provides guidance for improving the Census Bureau's program and for policy makers who use such estimates for allocating funds.

Improving Access to and Confidentiality of Research Data summarizes a workshop convened by the Committee on National Statistics (CNSTAT) to promote discussion about methods for advancing the often conflicting goals of exploiting the research potential of microdata and maintaining acceptable levels of confidentiality. This report outlines essential themes of the access versus confidentiality debate that emerged during the workshop. Among these themes are the tradeoffs and tensions between the needs of researchers and other data users on the one hand and confidentiality requirements on the other; the relative advantages and costs of data perturbation techniques (applied to facilitate public release) versus restricted access as tools for improving security; and the need to quantify disclosure risks--both absolute and relative--created by researchers and research data, as well as by other data users and other types of data.
Informing America's Policy on Illegal Drugs
What We Don't Know Keeps Hurting Us

How should the war on drugs be fought? Everyone seems to agree that the United States ought to use a combination of several different approaches to combat the destructive effects of illegal drug use. Yet there is a remarkable paucity of data and research information that policy makers require if they are to create a useful, realistic policy package-details about drug use, drug market economics, and perhaps most importantly the impact of drug enforcement activities. Informing America's Policy on Illegal Drugs recommends ways to close these gaps in our understanding-by obtaining the necessary data on drug prices and consumption (quantity in addition to frequency); upgrading federal management of drug statistics; and improving our evaluation of prevention, interdiction, enforcement, and treatment efforts. The committee reviews what we do and do not know about illegal drugs and how data are assembled and used by federal agencies. The book explores the data and research information needed to support strong drug policy analysis, describes the best methods to use, explains how to avoid misleading conclusions, and outlines strategies for increasing access to data.Informing America's Policy on Illegal Drugs also discusses how researchers can incorporate randomization into studies of drug treatment and how state and local agencies can compare alternative approaches to drug enforcement. Charting a course toward a better-informed illegal drugs policy, this book will be important to federal and state policy makers, regulators, researchers, program administrators, enforcement officials, journalists, and advocates concerned about illegal drug use.

Reform of welfare is one of the nation's most contentious issues, with debate often driven more by politics than by facts and careful analysis. Evaluating Welfare Reform in an Era of Transition identifies the key policy questions for measuring whether our changing social welfare programs are working, reviews the available studies and research, and recommends the most effective ways to answer those questions. This book discusses the development of welfare policy, including the landmark 1996 federal law that devolved most of the responsibility for welfare policies and their implementation to the states. A thorough analysis of the available research leads to the identification of gaps in what is currently known about the effects of welfare reform. Evaluating Welfare Reform in an Era of Transition specifies what-and why-we need to know about the response of individual states to the federal overhaul of welfare and the effects of the many changes in the nation's welfare laws, policies, and practices.With a clear approach to a variety of issues, Evaluating Welfare Reform in an Era of Transition will be important to policy makers, welfare administrators, researchers, journalists, and advocates on all sides of the issue.
