THE NATIONAL ACADEMIES
Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council.

Preface
A growing body of evidence indicates that many factors outside the traditional health field affect public health. The idea that our health is determined only by our own behavior, choices, and genetics is no longer tenable. Many now recognize that substantial improvements in public health will occur only by ensuring that health considerations are factored into projects, programs, plans, and policies in non-health-related sectors, such as transportation, housing, agriculture, and education.
Health impact assessment (HIA) is a tool that can help decision-makers identify the public-health consequences of proposals that potentially affect health. Because of the potential that HIA offers to improve public health, the Robert Wood Johnson Foundation, the National Institute of Environmental Health Sciences, the California Endowment, and the U.S. Centers for Disease Control and Prevention asked the National Research Council to develop a framework, terminology, and guidance for conducting HIA.
In this report, the Committee on Health Impact Assessment discusses the need for health-informed decision-making and policies and reviews the current practice of HIA. The committee provides a definition, framework, and criteria for HIA; discusses issues in and challenges to the development and practice of HIA; and closes with a discussion on structures and policies for promoting HIA. The committee notes that the framework provided in this report is not a reinvention of the field but a synthesis of guidance provided in other documents and publications. Thus, the reader will find many similarities between the committee’s descriptions and characterizations and those of other guides.
The present report has been reviewed in draft form by persons chosen for their diverse perspectives and technical expertise in accordance with procedures approved by the National Research Council Report Review Committee. The purpose of the independent review is to provide candid and critical comments that will assist the institution in making its published report as sound as possible and to ensure that the report meets institutional standards of objectivity, evidence, and responsiveness to the study charge. The review comments and draft manuscript remain confidential to protect the integrity of the deliberative process. We thank the following for their review of this report: Jason Corburn, Uni-
versity of California, Berkeley; William H. Dow, University of California, Berkeley; Jonathan C. Heller, Human Impact Partners; Murray Lee, Habitat Health Impact Consulting; Jonathan Levine, University of Michigan; Linda A. McCauley, Emory University; David O. Meltzer, University of Chicago; Keshia M. Pollack, Johns Hopkins Bloomberg School of Public Health; Lindsay Rosenfeld, Northeastern University; Alex Scott-Samuel, University of Liverpool; Nicholas C. Yost, SNR Denton; Lauren Zeise, California Environmental Protection Agency.
Although the reviewers listed above have provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations, nor did they see the final draft of the report before its release. The review of the report was overseen by the review coordinator, Joseph V. Rodricks, Environ, and the review monitor, Gilbert S. Omenn, University of Michigan Medical School. Appointed by the National Research Council, they were responsible for making certain that an independent examination of the report was carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of the report rests entirely with the committee and the institution.
The committee gratefully acknowledges the following for their presentations: Marice Ashe, Public Health Law and Policy; John Balbus, National Institute of Environmental Health Sciences; Ronald Bass, ICF International; Larry Cohen, Prevention Institute; Andrew Dannenberg, U.S. Centers for Disease Control and Prevention; Paul Farmer, American Planning Association; Ed Fogels, Alaska Department of Natural Resources; Robert Gould, Partnership for Prevention; Ralph Keeney, Duke University; Jenelle Krishnamoorthy, U.S. Senate Committee on Health, Education, Labor, and Pensions; Angelo Logan, East Yard Communities for Environmental Justice; April Marchese, U.S. Department of Transportation; John Norquist, Congress for the New Urbanism; Linda Rudolph, California Department of Public Health; Pamela Russo, Robert Wood Johnson Foundation; and Terry Williams, Tulalip Natural Resources Treaty Rights Office.
The committee is also grateful for the assistance of the National Research Council staff in preparing this report. Staff members who contributed to the effort are Ellen Mantus, project director; Heidi Murray-Smith, program officer; Keri Schaffer, research associate; James Reisa, director of the Board on Environmental Studies and Toxicology; Norman Grossblatt, senior editor; Mirsada Karalic-Loncarevic, manager, Technical Information Center; Radiah Rose, manager, editorial projects; and Panola Golson, program associate.
I would especially like to thank the members of the committee for their efforts throughout the development of this report.
