asked the Secretary of State for the Environment what is the percentage of owner-occupied housing for each year since 1979 for the Northern region and the Bishop Auckland constituency.

Estimates of the owner-occupied dwelling stock in the North (standard) region at the end of 1979, 1980 and 1981 are published in "Housing and Construction Statistics" annual volumes 1969–1979, 1970–1980 and 1971–1981, respectively, copies of which are available in the Library. No estimates have been made of the owner-occupied dwellings in the Bishop Auckland constituency.
