Other relevant research: World population growth – This article is focusing on the history of population growth up to the present. We show how the world population grew over the last several thousand years and we explain what has been driving this change. The annual growth rate of the world population in 2019 is around 1.1% and is predicted to decrease even more in the next few decades, continuing the trend of slower population growth. To calculate growth rate, start by subtracting the past value from the current value. Then, divide that number by the past value. Finally, multiply your answer by 100 to express it as a percentage. For example, if the value of your company was $100 and now it's $200, first you'd subtract 100 from 200 and get 100.

Specifically, population growth rate refers to the change in population over a unit time period, often expressed as a percentage of the number of individuals in the population at the beginning of that period.

We can expect the world's population of 6.5 billion to become 13 billion by 2067 if current growth continues. The world's growth rate peaked in the 1960s at 2% and a doubling time of 35 years.
