Global Risks Report, 2016

2012-2020 method: Global Risks Perception Survey of the Forum's multistakeholder community; each global risk rated for likelihood and impact over a 10-year horizon on a numeric scale (1 to 5 confirmed in the 2012 and 2020 reports; not checked for other years). The size of the risk set changed: 50 risks in 2012, 31 in 2014, 30 in 2020. The risk list and definitions changed between years (for example cyberattacks, income disparity and unemployment entered in 2012). Label and category as printed in WEF's own 'Evolving Risks Landscape, 2007-2020' figure (Global Risks Report 2020, Figure I). The figure uses short labels; the edition's own report may word the risk differently. Category read from the figure's colour key. Cross-checked: for 2012-2020 the Global Risks Report 2021 Figure IV prints the same top 5 labels and colours. Top 5 per ranking only; the edition's own report may rank more risks.
