How's the birth rate in India or the african countries?
Africa fertility rate is dropping around 1.5% per year annually for the region as a whole.
Increasingly technologized populations drop fertility fast
And some refusal to use condoms.
If this changes, the trend will sharply reverse.
Most forecast say population will peak at 10bn to 11bn - https://ourworldindata.org/future-population-growth
- A big part of this increase in indeed from Africa which is expected to increase by 3bn - from 1.3bn in 2020 to 4.3bn in 2100
- The largest uncertainty is also about Africa where faster economic growth is expected to bring down population growth (counter-intuitively).
To illustrate the point: The last 40 years have been the worst we will see in terms of stability, economic growth etc .... yet Population growth in Africa thrived and the % of people living in poverty reduced dramatically and the current population is healthier, wealthier, and more educated than ever before (https://ourworldindata.org/grapher/above-or-below-extreme-po... ).
Once you start increasing quality of life and education, birth rates will plummet.
It would only be “over population” because our current in-effecient systems can’t keep up and they need to evolve.
