By mid-2028, the population of the UK is set to increase by three million to 69.4 million, primarily driven by immigration.
According to projections published on Monday by the Office for National Statistics (ONS), 73 per cent of the growth is predicted to be due to the net international immigration of 2.2 million people.
Less than one-third, 27 per cent, of the increase will be due to natural population growth (more births than deaths).
The ONS also predicts that the population will pass the 70 million mark by mid-2031.
However, The Times noted that the 70 million mark could be hit far sooner. Based on a higher projection offered by the ONS, where net migration runs at around 290,000 a year, that level could be reached in the next eight or nine years.
