The field of Health Impact Assessment is relatively new to the United States, but already a number of state and local governments are incorporating these assessments into land use planning and decision making. In five years, the use of HIA in the U.S. has increased dramatically with more than 100 HIAs completed or in progress in the U.S. from 2007 to 2010. This article provides a brief overview of HIA in the United States, describes how it is being used in other states with respect to land use decision making, and examines how HIA is starting to be incorporated into traditional land use and environmental decision making in New York.
