§ Mr. Deakins
asked the Secretary of State for Trade and Industry what is the correlation between the United Kingdom growth rate in gross national product and productivity increases in industry, including agriculture.
§ Mr. Ridley
Industries covered by the index of industrial production, together with agriculture, forestry and fishing, contribute about half of the gross national product of the United Kingdom. Over the period 1963–70, the overall increase in output per head in these sectors, estimated at about 4 per cent. per annum, has accounted for some two-thirds of the average annual growth in gross national product of slightly under 3 per cent.
