Summary

Story summary

Britain's population is set to soar to 74.3 million by 2100, a remarkable 6.8% rise, largely thanks to immigration, as per UN estimates. With a net influx of 14.3 million people, this growth outpaces other EU nations. In contrast, without this migration, the population could plummet below 50 million due to declining birth rates and an aging society.
