Population in the world is currently (2019-2020) growing at a rate of around 1.08% per year (down from 1.10% in 2018 1.12% in 2017 and 1.14% in 2016). The current average population increase is estimated at 82 million people per year.

Annual growth rate reached its peak in the late 1960s when it was at around 2%. The rate of increase has nearly halved since then and will continue to decline in the coming years.

World population will therefore continue to grow in the 21st century but at a much slower rate compared to the recent past. World population has doubled (100% increase) in 40 years from 1959 (3 billion) to 1999 (6 billion). It is now estimated that it will take another nearly 40 years to increase by another 50% to become 9 billion by 2037.
