Notes:
(1) The current price estimates are derived from the censuses of production for 1963, 1968, 1971 and 1972. The construction industry was not covered in the last two censuses.
(2) The estimates for 1971 and 1972 are provisional, particularly those for 1972. The provisional results for 1972 are expected to be published in a Business Monitor by the end of 1973.
(3) Census of production information does not relate completely to calendar years but partly to firms' own financial years. In particular, the current price estimates for 1968, 1971 and 1972 for coal mining relate to years ending at about the end of March. The effects of the miners' strike in early 1972 will therefore mainly appear in the 1971 estimates.

Mr. Nott

The following is the information available:

(4) No estimates can yet be made at 1973 prices and in the constant price estimates the index of production, which is constructed on 1970 prices, has been used to measure movements in net output. Data on employment have been taken from Department of Employment sources except for construction where Department of Environment estimates have been used to maintain greater consistency with the output estimates.
(5) Estimates of net output per £1 sterling of labour costs at constant prices are not available.
(6) Because of the use of different sources and the different periods to which the estimates relate the current and constant price estimates are not completely comparable.
(7) In both sets of estimates persons employed include employers and self-employed persons: full-time and part-time workers are counted as whole units.
