As defined in 2011 by the National Research Council of the National Academies, an “HIA [health impact assessment] is a systematic process that uses an array of data sources and analytic methods and considers input from stakeholders to determine the potential effects of a proposed policy, plan, program, or project on the health of a population and the distribution of those effects within the population. HIA provides recommendations on monitoring and managing those effects.”

This is a longitudinal dataset displaying all HIA bills introduced between January 1, 2012 and December 31, 2016. As such, no HIA bills introduced prior to January 1, 2012 are included. For legislation prior to January 1, 2012 please see the National Conference of State Legislatures' An Analysis of State Health Impact Assessment Legislation.
