People Pause

The world's population isn't growing:

For decades, we’ve been told that the world’s biggest problem is too many people. From Malthus in the 18th century to “The Population Bomb” in the 1960s, the warnings were dire: More people would mean more famine, more poverty, more environmental destruction. But something unexpected has happened. The demographic math has changed. And the United Nations, the world’s most cited authority on population forecasts, has taken notice. Until recently, their models predicted that the global population would continue to grow throughout the 21st century, reaching a peak of nearly 11 billion by the year 2100. But in its 2022 and 2024 revisions, the U.N. quietly lowered its global population projections. The most recent estimate puts the peak at just 10.3 billion, and it comes nearly two decades earlier, around 2084. .... Over the last decade, several independent teams of researchers have developed alternative population projections. Most of them show that fertility will drop faster than the U.N. is predicting. A team at the University of Washington’s Institute for Health Metrics and Evaluation (IHME), for example, gained wide attention in 2020, when it projected that the global population would peak around 2064 at just over 9 billion and decline to about 8.8 billion by 2100. Wolfgang Lutz, one of the world’s most respected demographers, has also published projections showing a lower and earlier population peak. Lutz’s group at the Wittgenstein Centre for Demography and Global Human Capital bases its models on education and urbanization trends, which are closely tied to fertility behavior. In a 2024 analysis of surveys involving over a million women in Sub-Saharan Africa, Lutz and his co-authors concluded that fertility rates there are falling faster than expected, especially as female education improves.
