Changes in occupational mix in engineering 1964–1972

Changes in the occupational structure could arise from different rates of output, and hence employment, growth in sectors of engineering or from changes in the occupational mix of the sectors. Almost all the change arises from the latter and, more importantly, the rate of change is not constant. Changes in the sector occupational mix will follow from investment and an understanding of this relationship is crucial to progress in manpower demand forecasting.
