asked the Minister of Health if any estimate has been made of

The only estimate on the lines suggested by the hon. and gallant Member of which I am aware is contained in a report of a Committee appointed by the Minister of Reconstruction, a copy of which I am sending him.

asked the Minister of Health if any estimates have been made of the quantities of the carious materials required for the erection of each or any of the types of houses erected under the housing schemes; and, if so, what they are?

Estimates of the quantities of materials required for the erection of various types of houses erected under the housing schemes have been made. When set out in detail the list of materials required is somewhat lengthy, but a general summary of the quantities of the principal materials required in the erection of two types—a parlour house and a non-parlour house—is as follows:the number of houses required since 1914, based on the number of marriages during the period; if so, what it is; and what was the number of marriages and the increase in the number of houses in each of the decennial periods, 1901–1910 and 1911–1920?

I do not think that the statistics of marriages in themselves give a reliable basis for estimating the number of houses required. The number of marriages in England and Wales between 1901 and 1910 was 2,640,515, and the increase in the number of buildings between the censuses in 1901 and 1911 was 841,000. The number of marriages between 1911 and 1920 was 3,075,903, and the increase in the number of structually separate dwellings between the censuses of 1911 and 1921 was 357,000.
