HC Deb 27 November 1952 vol 508 c95W
Dr. Stross

asked the Minister of Housing and Local Government for an estimate of the number of occupied dwellings in England and Wales which have fallen into such disrepair that they cannot be rendered fit for human habitation at a reasonable cost of repair.

Mr. H. Macmillan

I do not think there is any means of making a reliable estimate short of a detailed survey.
