The chart shows the annual rate of global population growth according to historical estimates and projections from the UN World Population Prospects.
The growth rate peaked in 1963 at over 2% per year, and since then, it has more than halved, falling to less than 1% by 2020.
The UN demographers expect rates to continue falling until the end of the century, eventually leading to negative growth rates and a shrinking global population.
