Why use HIA?
HIA is based on four values that link the HIA to the policy environment in which it is being undertaken.
- Democracy – allowing people to participate in the development and implementation of policies, programmes or projects that may impact on their lives.
- Equity – HIA assesses the distribution of impacts from a proposal on the whole population, with a particular reference to how the proposal will affect vulnerable people (in terms of age, gender, ethnic background and socio-economic status).
- Sustainable development – that both short and long term impacts are considered, along with the obvious, and less obvious impacts.
- Ethical use of evidence – the best available quantitative and qualitative evidence must be identified and used in the assessment. A wide variety of evidence should be collected using the best possible methods.
