Shrinking populations mean less growth and a more fractious world

If current forecasts are accurate, 2064 will be the first year in centuries when fewer babies are born than people die. Birth rates in India will fall to below the level seen in America last year. Even with immigration and successful pro-natal policies, America’s population will only have a little bit of growth left. By 2100 there will be many fewer migrants left to attract. The world’s fertility rate will hit 1.7. Just two Pacific islands and four African countries will manage to reproduce above replacement level.
