After several years of chronic shortages of trained personnel, the economic recession of the past two years has resulted in some unemployment within the computer field. This unemployment has emphasized the long existing need for better overall manpower planning. Such planning can only be carried on successfully if reasonably reliable data and projections are available. The information collected and the resulting projections must include both the employment needs and the sources of trained personnel. The purpose of this paper is to summarize the current employment picture especially as it relates to the users of computers. A companion paper in these proceedings discusses the primary sources of such trained personnel.
