The EVI or Economic and Environmental Vulnerability Index is a measure of structural vulnerability to economic and environmental shocks. High vulnerability indicates major structural impediments to sustainable development. Thus, a higher EVI represents a higher economic vulnerability. (Note: In 2020, the United Nations Committee for Development Policy (CDP) approved adjustments to the Economic and Environmental Vulnerability Index (EVI), previously named the Economic Vulnerability Index. Information about the changes adopted can be found in the Report on the twenty-second session (24-27 February 2020) of the CDP, Economic and Social Council document E/2020/33, Official Records 2020, Supplement 13 (https://undocs.org/en/E/2020/23)).
Since 2015 the CDP uses absolute thresholds for the EVI to determine inclusion and graduation eligibility. The inclusion threshold has been set at 36. The graduation threshold has been set at 10 per cent below the inclusion threshold at 32. The EVI is composed of eight indicators, grouped into various subindices. Original values for each EVI indicator are converted into index numbers using a max-min procedure.
