UN projections have also been dropping over time:

> Its previous release projected that the world population would be around 10.88 billion in 2100 and would not yet have peaked.

> In this new release, the UN projects that the global population will peak before the end of the century – in 2086, at just over 10.4 billion people.

> There are several reasons for this earlier and lower peak. One is that the UN expects fertility rates to fall more quickly in low-income countries compared to previous revisions. It also expects less of a ‘rebound’ in fertility rates across high-income countries in the second half of the century.
