§ Mr. Thomas Coxasked the Chancellor of the Exchequer which industries have increased their yearly productivity during the last 10 years at a higher rate than that achieved by the electricity supply industry.
§ Mr. HigginsThis information is not available. Estimates of changes in output per head are calculated only for those industrial groupings where overall the coverage of the output and employment data is reasonably close. These appear in theMonthly Digest of Statistics and in the Employment and Productivity Gazette. The basis of the estimates and their limitations were described in an article which appeared in the October, 1968, issues of both Economic Trends and the Employment and Productivity Gazette.
