asked the Secretary of State for the Environment if he will publish in the Official Report (a) the average local authority unrebated rents for the years 1975–76 to 1981–82 inclusive, (b) the average local authority rebated rents for the years 1975–76 to 1981–82 inclusive and (c) the average income, net of all statutory deductions, of local authority tenants for the years 1975–76 to 1981–82 inclusive.

The available figures on the average unrebated rent of local authority tenants in England and Wales from 1975–76 to 1981–82, and for the average rebated rent as at April and October 1975–81 are given in the following tables. The average net disposable income data collected in the course of the family expenditure survey has not been analysed by household tenure.

Table 1
Year	Average unrebated rent (£ per dwelling per week)
1975–76	4·28
1976–77	4·91
1977–78	5·58
1978–79	5·90
1979–80	6·48
1980–81	8·18
1981–82	11·50

Note:These figures are estimated from the returns which authorities make to the Chartered Institute of Public Finance and Accountancy (CIPFA) each April, returns they make to the Department of Employment for retail price index purposes each October and, for 1980–81 and 1981–82, the subsidy claim forms they return to the Department of the Environment.

Note:These figures derive from returns which local authorities make to the Department of Employment for retail price index purposes. The average rebated rent is by convention the average rent payable by tenants, net of any rent rebates received, but counting in full the rent paid by tenants receiving supplementary benefit. Average rebated rent figures are not available for financial years.
