§ Mr. Gryllsasked the Secretary of State for Trade and Industry if he will give the current figures for 596W concentration ratios by standard industrial classification similar to those included in the 1978, White Paper, Command 7178, "A Review of Monopolies and Mergers Policy".
§ Mr. Alexander Fletcher[pursuant to the reply, 15 December 1983]: The main figures for concentration ratios by standard industrial classification were those for 1972 (the most recent year then available) set out in table 2 of the 1978 Green Paper Cmnd. 7198, "A Review of Monopolies and Mergers Policy." The most recent figures available on the same basis as those at table 2 are for 1979, as follows.
Five firm employment concentration ratios 1979 Industrial Order No. of Industries in each Order Weighted average percentage of employment in the five largest firms in each Industry Mining and quarrying 2 41 Food, drink and tobacco 12 53 Coal and petroleum products 1 43 Chemical and allied industries 13 57 Metal manufacture 5 58 Mechanical engineering 17 33 Instrument engineering 3 36 Electrical engineering 9 58 Shipbuilding and marine engineering 1 76 Vehicles 5 69 Other metal goods 7 45 Textiles 8 34 Leather and fur 2 20 Clothing and footwear 7 24 Bricks pottery etc. 6 45 Timber, furniture etc. 4 15 Paper, printing etc. 6 25 Other manufacturing 6 47 Total manufacturing and extractive 114 48 SourceBusiness Monitor PA1002.
The most up to date figures are those for 1980, as follows (the figures for 1980, which were based on the 1980 SIC, are not comparable with the data for 1972 and 1979, which were based on the 1968 SIC):

Supplementary figures for 1972 concentration ratios were given in Annex A of the Green Paper. Corresponding figures for 1979 and (on a non-comparable basis) for 1980 can be derived from published data in the Business Monitor PA 1002 for 1979 and 1980 but the data could not be extracted except at disproportionate cost.
