The Global Risks Perception Survey (GRPS) respondents were asked to assess the likelihood of the individual global risk on a scale of 1 to 7, with 1 representing a risk that is not likely to happen and 7 a risk that is very likely to occur. They also assessed the impact of each global risk on a scale of 1 to 5 (1: minimal impact, 2: minor impact, 3: moderate impact, 4: severe impact and 5: catastrophic impact).
The GRPS is the main instrument used to assess global risks in the Report. The survey was conducted between early September and mid-October 2016 (from 07 September to 15 October 2016) among the World Economic Forum’s multi-stakeholder communities of leaders from business, government, academia and non-governmental and international organizations as well as members of the Institute of Risk Management.
See Appendix B of the Report for more details. To ensure legibility, the names of the global risks are abbreviated; see Appendix A for the full name and description.
