Elon Musk warns of a potential population collapse, emphasizing that the U.S. fertility rate has fallen to 1.62. A recent study suggests a revised target of 2.7 children per woman, taking into account factors like mortality rates and reproduction probabilities. The decline in global birth rates from 5.3 in the 1960s to 2.3 in 2023 highlights the urgency of the situation. Researchers argue that achieving true sustainability, not just in population but also in cultural diversity, requires revisiting traditional fertility benchmarks.
Considering stochasticity [unpredictability] in fertility and mortality rates, and sex ratios, a fertility rate higher than the standard replacement level is necessary to ensure sustainability of our population.
The underpopulation crisis has been a serious threat to the sustainability of developed countries.
Musk has been sounding the alarm on worldwide population collapse for years, claiming it will be 'the biggest problem the world will face in 20 years.'
The worldwide total fertility rate - the number of children per woman - has dropped from 5.3 in the 1960s to 2.3 in 2023.
