A major study predicts that almost every country's population will be shrinking by the end of the century due to low fertility rates, with implications for global economy and societal reorganization.
Key Points
Fertility rates in half of all nations are already too low to maintain population size
By 2050, three quarters of all countries will have shrinking populations
97% of countries are projected to have shrinking populations by the end of the century
Developing countries will see fertility rates increase while wealthier nations will see declines
Pros
Potential benefits for the environment and food security with a smaller population
Reorganization of societies and global economy may lead to new opportunities
Cons
Challenges in labor supply, social security, and nationalistic geopolitics
Reliance on open immigration may become necessary for economic growth
