§ Mr. Worsleyasked the Secretary of State for the Environment what changes there were in the stock of dwellings in London between 1961 and 1966 and between 1966 and the latest dales for which estimates are available.
§ Mr. ChannonBetween the census of 1961 and 1966, 130,000 dwellings were completed in London, 32,000 were closed or demolished in slum clearance action and there was a net loss of 17,000 from other causes, giving a net increase of over 70,000. Between April, 1966, and the end of 1970, 158,000 dwellings were completed, and there were 35,000 losses from slum clearance and 16,000 other losses, net, so that the total stock increased by about 105,000. Details are shown below.
Comparison of the numbers of dwellings enumerated in the 1961 census and the 1966 sample census, 2.41 million and 2.35 million, would indicate a reduction rather than an increase, but it is known that dwellings were over-estimated in 1961 and under-estimated in 1966. My officials estimate the amount of the error in London as about 90,000 in 1961 and 50,000 in 1966.
