REPORTED IS A NATIONAL SCIENCE FOUNDATION (NSF) STUDY OF SCIENTIFIC MANPOWER. THE PRINCIPAL OBJECTIVES WERE THE ESTABLISHMENT OF TRENDS AND THE ILLUMINATION OF FACTORS THAT SIGNIFICANTLY AFFECT FUTURE REQUIREMENTS FOR SCIENCE AND ENGINEERING ACADEMIC STAFF IN HIGHER EDUCATION. THE DATA WERE DERIVED FROM SURVEYS COMPLETED BY NSF, NATIONAL ACADEMY OF SCIENCES - NATIONAL RESEARCH COUNCIL, U.S. OFFICE OF EDUCATION, AND OTHERS. SOME TRENDS INDICATED FOR THE 1965-75 PERIOD ARE (1) TEACHING AND RESEARCH WILL BE THE PRIMARY ACTIVITIES IN HIGHER EDUCATION, AND WILL LARGELY DETERMINE STAFF NEEDS, (2) THE EMPLOYMENT OF SCIENCE AND ENGINEERING STAFF WILL NEARLY DOUBLE AS A RESULT OF EXPANDING ENROLLMENT AND RESEARCH NEEDS, (3) THE REQUIREMENTS FOR DOCTORATES IN THESE FIELDS WILL GREATLY EXCEED THE SUPPLY AVAILABLE IN THE EARLY PART OF THE PERIOD, (4) BY THE MIDDLE OF THE DECADE THE GROWING NUMBER OF DOCTORATES WILL CAUSE THE SITUATION TO IMPROVE, ALTHOUGH THE PROPORTION OF SCIENCE STAFF HOLDING THE DOCTORATE DEGREE AT THE END OF THE DECADE WILL NOT BE AS HIGH AS THE 1965 RATIO. THE APPENDIXES PRESENT DATA CONCERNING (1) THE ESTIMATED SCIENTIFIC MANPOWER REQUIREMENTS FOR TEACHING AND RESEARCH, (2) SCIENCE AND ENGINEERING STAFF SUPPLY AND DEMAND FOR PERSONS HOLDING DOCTORATE DEGREES, AND (3) ESTIMATED PRODUCTION OF PEOPLE HOLDING DEGREES IN SCIENCE AND ENGINEERING FIELDS. THIS DOCUMENT IS ALSO AVAILABLE FOR $0.30 FROM THE SUPERINTENDENT OF DOCUMENTS, U.S. GOVERNMENT PRINTING OFFICE, WASHINGTON, D.C. 20402. (DS)
