> Yes. France has a better housing supply, and roughly the same area. But France has over twice the area, and under half the population density, even before you account for the almost uninhabited mountainous areas in Wales, Northern England and Scotland. So our populations are squeezed into smaller areas.

If you compare population density maps of France vs the UK, you can see that it's pretty similar - there are clusters of population in certain locations, and wide areas with barely any inhabitants.
