Global Demographic Outlook 2020

Global population witnessed an unprecedented growth in recent decades. From reaching 4 billion in 1974, 6 billion in 1999 and 7.8 billion people this year, the world’s population is set to reach the 8-billion mark in the very near future. This rapid growth will affect less developed nations the most; however, in strong contrast, economically advanced countries across the globe will witness a sharp drop in population, due to a set of mutually-aligned trends. Fertility rates under the 2.0-2.1 threshold required for a stable reproduction rate, combined with an increasing life expectancy, mean that these states will not only have fewer citizens, but will also have to find a solution for the increasing pressure on their current pension system, as a declining number of workers will have to support a growing number of pensioners.
