as most highly vulnerable is projected to grow significantly. A study using five vulnerability categories globally concludes that the total population of all countries with very high vulnerability  is projected to increase from 2019 numbers approximately by 102% by 2050  and 257% by 2100, while the population of all countries with very low vulnerability is projected to decrease by 9% by 2050 and 17% by 2100 . Another study estimates that the total population of all countries classified at most vulnerable  is predicted to increase by 82% by 2050 and 192% by 2100. In contrast the population of all countries classified as least vulnerable  is projected to only increase by 9% by 2050 and 1% by 2100 .
