New study warns major economies face population drops of 20-50% by 2100 due to low birth rates.

A new study warns that major economies could see their populations fall by 20-50% by 2100 due to declining birth rates. Two-thirds of the world's population is in countries where families have fewer than 2.1 children. This trend could slow economic growth and increase the burden on younger generations to support more retirees. The study suggests that increasing fertility rates, productivity, and labor intensity could help, but adapting will take time.
