Health Impact Assessment (HIA)
The World Health Organization defines HIA as "A combination of procedures, methods and tools by which a policy, program or project may be judged as to its potential effects on the health of a population, and the distribution of those effects within the population." HIAs are being implemented at a growing rate throughout Europe as a way to effectively gauge the health impacts of land use planning and policy decisions. While the knowledge and use of HIA processes is currently minimal in the United States, some agencies, such as the San Francisco Department of Environmental Health, are beginning to use community-based HIAs. As health problems related to the built environment increase, local public health officials are taking a greater interest in land-use planning decisions and, thus, a greater interest in tools such as HIA.list of links that pertain to HIA. Some of these Web sites have a thorough resource database on HIAs with toolkits, research, and proven examples of HIA, while others may contain only a single report on HIA or a bibliography with references to other documents on HIA.
