Analysed Indicators

For the examination of the CRI, the following indicators were analysed:

1. 
   number of deaths,
   
2. 
   number of deaths per 100 000 inhabitants,
   
3. 
   sum of losses in US$ in purchasing power parity (PPP) as well as
   
4. 
   losses per unit of gross domestic product (GDP).
   

For the indicators 2–4, economic and population data primarily provided by the International Monetary Fund were taken into account. It must be added, however, that especially for small (e.g. Pacific Small Island Developing States) or extremely politically unstable countries (e.g. Somalia), the required data are not always available in sufficient quality for the entire time period observed. Those countries needed to be omitted from the analyses.

The CRI 2021 is based on the loss figures of 180 countries from the year 2019 and the period 2000 to 2019. This ranking represents the most affected countries. In each of the four categories ranking is used as a normalisation technique. Each country's index score has been derived from a country's average ranking in all four indicating categories, according to the following weighting: death toll, 1/6; deaths per 100 000 inhabitants, 1/3; absolute losses in PPP, 1/6; losses per GDP unit, 1/3.

For example, in the Climate Risk Index for 2000-2019, Bangladesh ranks 9^th in annual fatalities among all countries analysed in this study, 37^th in Fatalities per 100 000 inhabitants, 13^th in losses and 37^th in losses per unit GDP (see Annexes, Table 4). Hence, its CRI Score is calculated as follows:

CRI Score = 9 x 1/6 + 37 x 1/3 + 13 x 1/6 + 37 x 1/3 = 28.33

Only six countries have a lower CRI Score for 2000-2019, hence Bangladesh ranks 7^th in this index category (see Table 2).
