Plenty has been written over the years about the decline in fertility rates throughout many parts of the world.

Researchers at the University of Washington’s Institute for Health Metrics and Evaluation are out with new research that shows the world’s population may hit a grim milestone by 2100.
The researchers found that as a result of falling fertility rates—which is the average number of children a woman gives birth to, nearly every country in the world could have a declining population by the year 2100.
Once the fertility rate falls below 2.1, populations begin to decline. For context, the fertility rate was 4.7 in 1950 and had fallen all the way to 2.4 in 2017. The researchers predict that the fertility rate will decline to 1.7 by 2100.
They predict that 23 countries, such as Japan, Spain, South Korea and Thailand, will see their populations decline by roughly half by 2100 as a result of declining fertility rates.
The researchers predict the global population will peak at 9.7 billion around 2064, after which it will fall to 8.8 billion by 2100. They note that 183 out of 195 countries will have fertility rates below the 2.1 threshold by then.
“That’s a pretty big thing; most of the world is transitioning into natural population decline,” researcher Professor Christopher Murray told the BBC. “I think it’s incredibly hard to think this through and recognize how big a thing this is; it’s extraordinary, we’ll have to reorganize societies.”
China, which is the world’s most populous country, will see its population peak in about four years at 1.4 billion before falling to 732 million by 2100. India is expected to take China’s place as the world’s most populous nation. …
