Assume positive intent. I flagged your comment because you made a false and scurrilous insinuation about my intentions. I'm not a UK citizen or resident and don't care about their immigration policy one way or another. But a high immigration rate will obviously increase housing demand: this is basic macroeconomics and trivially true.

The UK net immigration rate has been high relative to other countries worldwide, especially in recent years. It is an outlier on that basis. I'm not sure why you would limit the comparison to only high-income countries.
