Scientific manpower problems

There has been a great deal of discussion during recent years of the problems arising from the shortage of scientists and engineers. This is a serious problem but unfortunately it is also a complex one. Hence there is confusion, both as to the facts and as to the remedies. It is desirable, therefore, to be clear about what factors are affecting the demand for scientists and engineers; what factors are influencing the supply; which of these various factors are long- and which are short-term in nature and finally which remedies should be considered for the short-term or the long-term problem.
