HC Deb 01 February 1972 vol 830 c92W
Mr. Chichester-Clark

asked the Secretary of State for the Environment whether he will set out in tabular form the percentage change in productivity in the construction industry in each of the last 10 years.

Mr. Channon

There is no productivity index for construction but figures relating to operatives employed by contractors on new work show that, after correcting for price changes, the average gross output per operative changed over each of the last 10 years as follows:

Year Percentage change over the previous year
1962 0
1963 +4
1964 +7
1965 +7
1966 +2
1967 +7
1968 +7
1969 +3
1970 +7
1971 (estimated) +8
Percentages have been rounded to the nearest 1 per cent.
