In the chart, we see the global population growth rate per year. This is based on historical UN estimates and its medium projection to 2100. Global population growth peaked in the 1960s at over 2% per year.
The world population has changed dramatically over the last few centuries. Let’s examine long-run population data to understand this change and how quickly the world’s population is growing today. The chart shows the increasing number of people living on our planet over the last 12,000 years.
Population by country, available from 10,000 BCE to 2023, based on data and estimates from different sources. HYDE (2023); Gapminder (2022); UN WPP (2024) – with major processing by Our World in Data.
Historical national accounts estimates of the share of the world's population living on less than $5 per day, by region; How do UN Population projections compare to the previous revision? Marriages per 1,000 people; Natural population growth with UN projections; Natural population growth rate vs. child mortality rate
How do UN Population projections compare to the previous revision? Marriages per 1,000 people; Natural population growth with UN projections; Natural population growth rate vs. child mortality rate; Natural population growth rate vs. median age; Number of deaths, by world region; Population since 10,000 BCE, Marimekko; Population 1950 to 2100 ...
As population growth continues to decline, the curve representing the world population is getting less and less steep. Towards the end of the century, the UN expects the global population to reach its peak at around 10.4 billion.
Average exponential rate of growth of the population over a given period. It is calculated as ln(P2/P1) where P1 and P2 are the populations on subsequent years. Available from 1700 to 2100, based on data and estimates from different sources.
In the chart, I’ve shown a range of these historical revisions, with their projections for the world population between 1970 and 2020. The UN’s latest population estimates – which is our closest estimate of the true population – are also shown for comparison.
Population by country, available from 10,000 BCE to 2100, based on data and estimates from different sources. Source. HYDE (2023); Gapminder (2022); UN WPP (2024) – with major processing by Our World in Data. Last updated.
Since 2019, the global population growth rate has fallen below 1%. That’s less than half its peak growth rate – of 2.3% – in the 1960s. As global fertility rates continue to fall (see below), this rate will continue to fall.
