>the white population of the UK has been increasing since the 40s
Actually, you're wrong. The White British population has indeed grown over the last 30 years, though not by much. However, it saw a significant decline in the 1960s and still hasn't returned to those levels, even though it has increased by a few hundred thousand each decade since 1970.
White population of England 1966:
46,540,500 98.73%
White poplation of England 2021:
45,783,401 81%
And that's including all the white immigrants. I doubt that there were that many non British whites in England in 1966.
What now William?
