Jamaica’s one of the islands in the Caribbean that arguably has come a long way if you believe Geoba.se which at this point its own fertility rate is now 1.94 children per woman with people living up to their seventies mostly owing to better education and efforts at birth control. While it’s still got its own problems at times, let’s not forget that it managed to catch up with many, if not most of, North America in fertility declines.
Many more Mexicans are expected to live up to their seventies as well and now there are around 2.17 children per woman over there. Canada fares at around 1.60 children per woman and America at 2.06 births per woman. As for both Mexico and Jamaica, it’s also got to do with rapid economic growth and industrialisation that would’ve been unthinkable (to some) before.
It’s safe to say that both Jamaica and Mexico are firmly within Stage 3 of demographic transition.
