More of our people and resources will disappear
In 2046, 33 years from now, it will be circa 6.7 million people, up from 4.5 million today. We can take it that this is a sort of accepted national plan and our planners will make hay with it, as best they can.
It’s a rise of 2.2m people, about 70,000 people per year. Our native birth rate is almost flat, like most Europeans; for the coming decade at least we will lose our own young people, maybe as many as 70,000 per year, as is now happening, and they will be replaced by immigrants, mostly non-Europeans, it seems, or fringe Europeans, or people of special status.
