asked the Secretary of State for Social Services if he will state both the level and the percentage change each year since 1979 in total National Health Service gross revenue expenditure based on the National Health Service pay and prices index, and after deduction each year of an appropriate demographic element to take account of the numbers of elderly people and the cost of medical technology; and, in separate columns, how large these latter two elements were for each of these years.

The information requested in the first part of the question is as follows:

NHS Revenue England (gross)—Percentage increase deflated by movements in NHS pay and prices
	Cash (£ million)	Percentage
1978–79	6,053
1979–80	7,223	-0·2
1980–81	9,402	+2·3
1981–82	10,488	+2·0
1982–83	11,477	+1·5
1983–84	12,169	+0·8
1984–85	13.027	+0·9
1985–86	13,740	-0·1

Calculations for demographic pressure and medical advance are not relevant to National Health Service expenditure as a whole. The information in respect of hospital and community health services expenditure was given to the hon. Member in my reply to him on 23 February at column
