This report is intended to give an indication of the variety of careers available to persons with interest and preparation in the mathematical sciences. Each part focuses on a particular class of professions, with necessary training as well as the character of the work and general conditions of employment described. Parts I through V deal with five areas in which the application of mathematics plays a major role: applied mathematics and engineering, computer science, operations/research, statistics, and the actuarial professions. Part VI deals with applications of mathematics to model building in other disciplines such as social sciences and biology. Parts VII and VIII are organized around the type of employer, with the first devoted to the teaching of mathematics at all levels and the second discussing the role of the mathematician in government, business, and industry. Part IX describes the value of an undergraduate degree in mathematics as preparation for a number of other professions not necessarily thought of as mathematical, such as business or law. In Part X, a list of references to publications and professional societies is given. (MNS)
