Part 2/11:
Back in the 1950s, women worldwide averaged nearly five children each (4.9). Today, that number has fallen sharply to around 2.4, with many nations dipping below the replacement rate of 2.1 children per woman. In the United States, the fertility rate stands at just 1.6, meaning the population is not reproducing enough to sustain itself naturally. This decline poses a significant threat to the long-term demographic and economic stability of nations.
