Probably more important to look at longer term demographic trends than a 1y change.

Fertility rates have halved in the last 60 years, and as a consequence, the developed world has a contracting population, as the fertility rates are now all below 2.

The only thing that accounts for population increases in those places (AU, EU, US etc) is immigration from other geographies.

The following table shows the change in fertility rates since 1960, and breaks that down across the major geographic regions of the world.

Note all of the 2021 rates that are below 2 - they are populations that will contract without immigration. The inescapable observation is the reduction in birthrates globally though - in part because of the improved medical care that has seen reduced infant mortality
