Health Impact Assessment FAQs

What is Health Impact Assessment?

Health Impact Assessment is a process by which the potential impacts of a project (such as a development project), proposal, or policy on public health can be evaluated prior to the implementation of the project, proposal, or policy.

What are the steps of an HIA?

There are six steps involved in conducting an HIA:

  • Screening
  • Scoping
  • Assessment
  • Recommendations
  • Reporting
  • Monitoring and Evaluation

How can the Tracking Network help me complete my HIA?

Data on the EPHT portal (Massachusetts and National portals) can be used during the Scoping, Assessment, and Monitoring and Evaluation steps of an HIA to either characterize baseline conditions or monitor changes after implementation. For more information about the EPHT Program and how CDC is supporting HIA work, visit the EPHT HIA page (http://ephtracking.cdc.gov/showHealthImpactAssessment.action#) and the CDC’s Healthy Places website (http://www.cdc.gov/healthyplaces/hia.htm).

Where can I find examples of other HIA projects?

Several examples of other projects are available in the “HIA Practice at DPH” section. A searchable tool of national HIA projects is available at the Health Impact Project’s website.

Who conducts HIAs?

Individuals conducting HIAs may have backgrounds in health, transportation, urban planning, environmental science, or other related fields. They often need to collaborate because they have different expertise. HIAs typically involve representatives from government, the community, nonprofit organizations, and sometimes developers.

Who else is providing guidance on HIAs?
