Pfr, what on earth are you expecting? I mean in WWII which was a much greater emergency. Families were evacuated, some returned, some didn't. Most of those who didn't chose not to. I would think that given a place in a rural community, the idea that you should move back to a deprived area of (for instance) London's East End, wouldn't be entirely welcome.

Same here to some extent, I know that people are clamouring to be rehoused in the borough, but sometimes I wonder why.
