The International Principles for Social Impact Assessment defines SIA as being “the processes of analysing, monitoring and managing the intended and unintended social consequences, both positive and negative, of planned interventions (policies, programs, plans, projects) and any social change processes invoked by those interventions”.
An SIA is an interdisciplinary process, and should employ various methods, both quantitative and qualitative. Social impact assessments should not be one-off exercises: To the contrary, they should be ongoing processes which engage with various stakeholders and which report back so as to ensure effective policy processes.
In this regard, you may refer to international SIA standards, for example those set by the International Association for Impact Assessment, which is accessible from this link:
