Been meaning to link to this for a few days. Mark Steyn basically predicts the death of most of the West, and it’s all due to birth rates. This is a long article, but worth reading in full.
The replacement fertility rate is 2.1 babies per woman. Less than that and your countries are going to lose population or you will need significant immigration to replace them.
The US is above the replacement rate with 2.07 births per woman. Ireland is 1.87, New Zealand 1.79, Australia 1.76, Canada 1.5, Germany and Austria are at 1.3, Russia and Italy are at 1.2; Spain 1.1, about half replacement rate. ThatTags: International Politics
