How many people are there in the world? How many die each year, and how many babies are born?
These are key questions that we need to understand the world around us. The global population dataset is one of our most important at Our World in Data: it underpins nearly every topic we cover.
The UN releases an update of its World Population Prospects every two years. Its latest release was due in 2021 but was delayed as a result of the COVID-19 pandemic. But, today – on World Population Day – the long-awaited dataset has been released.
In this article, we highlight some of the key findings of the twenty-seventh publication of the ‘World Population Prospects’.
With early access to this new UN data we have also published a new Population and Demography Data Explorer, where you can explore this full dataset in detail, for any country in the world.
