The UN Population Division report of 2022 projects world population to continue growing after 2050, although at a steadily decreasing rate, to peak at 10.4 billion in 2086, and then to start a slow decline to about 10.3 billion in 2100 with a growth rate at that time of -0.1%.
This estinmate is dropping almost every year. If the worlds population growth goes into reverse
How will we cope with a shrinking workforce, an aging population, and potential economic challenges, but also potentially lower resource consumption and environmental impact

@helenS research shows that infant mortality rate is the biggest issue - if you no longer need an heir and a spare you dont get the spare. Cointarception availability may be a afctor and financial ambition may be a factor. The decline in religious beliefs may also be a factor.
Studies suggest a global decline in male sperm counts, with some research indicating a decrease of over 50% in the past 50 years, potentially linked to environmental factors, lifestyle choices, and industrialization.
Unhealthy lifestyle choices, such as smoking, excessive alcohol consumption, drug use, obesity, and prolonged exposure to heat, can negatively impact sperm count and quality, potentially leading to male infertility.
Interesting - the good news is guys it does seem to be plateauing at 50%.
@Captain In 2025, there are six countries, all in Sub-Saharan Africa, where the average woman of childbearing age can expect to have between 5-6 children throughout their lifetime. In fact, of the 20 countries in the world with the highest fertility rates, Afghanistan and Yemen are the only countries not found in Sub-Saharan Africa. With a fertility rate of almost six children per woman, Chad is the country with the highest fertility rate in the world. Population growth in Chad is among the highest in the world. Lack of healthcare access, as well as food instability, political instability, and climate change, are all exacerbating conditions that keep Chad's infant mortality rates high, which is generally the driver behind high fertility rates.

@helenS Yep I knew that one - poverty and high infant mortality breeds babies -about as counter intuitive as you could imagine if you were an alien but exactly what you'd expect if yu were familiar with human society.
