§ Mr. Ellis Smithasked the President of the Board of Trade if he will set out in tabular form the percentage of their 150W total production and the value exported of the main industries for the years 1929, 1939, 1946, 1950 and on the latest convenient date.
§ Mr. MaudlingFigures of the value of production are not available for the years requested. The following table shows figures of the total gross value of production for major groups of industries in respect of the nearest years for which Census of Production statistics are available; the values of United Kingdom exports of relevant commodities are also shown.
£m Main industries Total Production U.K. Exports Chemicals and allied industries 1930 200 35 1935 215 30 1948 760 120 1954 1,690 290 1958 2,270 360 Metal manufacture 1930 215 65 1935 250 50 1948 970 160 1954 1,880 195 1958 2,320 280 Engineering and allied industries 1930 660 125 1935 750 90 1948 3,060 625 1954 5,630 1,190 1958 7,380 1,570 Textiles, leather and clothing 1930 710 175 1935 720 125 1948 1,970 345 1954 2,930 385 1958 2,770 315 The figures of production are aggregates of gross outputs of firms with no deductions made for the double-counting of components and semi-manufactured goods produced by one manufacturer and incorporated in the products of another. The figures for 1958 are on a different basis from those for earlier years as a result of the reclassification of firms in that year. Figures for all years contain estimates for firms not making returns or making unsatisfactory returns.
The export figures relate to commodities mainly produced in the industries specified. Figures for 1930, 1935, 151W and 1948 have been estimated and are not directly comparable with later years. Because of the differences between the two series the export figures cannot be related directly to the figures of production; the duplication in the latter tends to make the ratio between the two sets of figures understate the export performance of broad sectors of industry.
