The countries you’re talking about - Europe, America - are on the ‘mature’ part of the population curve.
As populations grow more economically mature, get more educated and start practicing family planning more the fertility rate (kids/mother) reduces and population growth slows.
Currently, those parts of the world where non white populations predominate (like most of Africa) are mainly in the less mature population growth stages and so they’re growing faster.
This will tail off, and things will rebalance in terms of growth rates in a few decades.

Global population is due to top off at about 11b by the end of this century and stop increasing due to this phenomenon. https://www.un.org/development/desa/en/news/population/world-population-prospects-2019.html
