This bulletin appraises some of the major technological changes emerging among American industries, and it projects the impact of these changes over the next 5 to 10 years on patterns of employment, occupations, and issues requiring labor-management adjustment. The bulletin extends and updates the report, "Technological Trends in 36 Major American Industries," which was issued in 1964 for the President's Advisory Committee on Labor-Management Policy. Major industries are covered in 40 separate reports in the bulletin, some covering groups of related industries, and the emphasis in each report is on the outlook for technological changes. Statistical data pertaining to productivity, production, employment trends, investment, and research development, all of which provide a quantitative basis for assessing the implications of technological change, are shown in charts and tables and are analyzed in the text. Among the implications were: (1) All industries will be affected, to some degree, by changes in equipment, methods of production, materials, and products, (2) Employment prospects in the industries studied are generally favorable, and (3) Prospective technological changes will continue to reduce the proportion of jobs involving primarily physical and manual ability and to increase the need for jobs requiring ability to work with data and information.
