Contained are the results and conclusions of a survey conducted in December, 1969, to ascertain the extent to which occupational deferments are an important factor in manpower utilization. A questionnaire was sent to employers in the following major employment categories - aerospace and defense; chemicals, metals and petroleum; construction and mining; electrical equipment; machinery and manufactured products; public utilities; research and technical services, and government agencies. These employers were asked to report the number of men between ages 19 and 26 who were currently occupationally deferred in Class II-A or for whom such deferments were being sought, and the total number of men with similar qualifications. They were also asked to give their estimate of the effect on the company if about half of these deferred men were drafted at random. The main findings are that (1) 13,310 in Class II-A are currently employed by 279 employers, (2) another 2,938 deferments are being requested, (3) the effect of abruptly eliminating deferments would be most widespread in the aerospace, research, chemical and petroleum industries, and (4) the effect would be focused most heavily on specific employers in nearly all industries, rather than on entire industries.
