raphers. Despite the fundamental contributions that have already been made by demographers in illuminating the inverse relationship between population growth and economic development, large areas of the problem remain obscure. No great increase in the effective contribution of population research is likely to occur without an increase in the number of good demographers. Fellowship support is needed in order to attract qualified students to graduate work in demography. In addition, funds are needed to help universities establish teaching and research posts, for at the present time graduate training in demography is available at only a few of the many outstanding American universities.
Similar needs exist in the social sciences, to provide competent investigators for motivational and attitudinal studies in the field of family planning. Finally, as indicated in the bio-medical section of this report, there is great need for increased research in a number of areas related to animal and human reproduction. This requires additional personnel. Increased support for existing laboratories and for individual investigators currently concerned with studies of specific aspects of the reproductive process will help to attract graduate students to this field of investigation. Graduate and postdoctoral training fellowships must be provided for qualified candidates. Support for schools of hygiene and public health concerned with the training of personnel in population problems must also be expanded.
2 Research laboratories for scientific investigation of the bio-medical aspects of human reproduction should be expanded.
The process of human reproduction is complex, and a thorough understanding of it will require extensive research by many investigators in universities, medical centers, and other research institutions.
There are at present a few laboratories concerned with human reproduction. We recommend that these laboratories expand their facilities and mobilize additional students and mature scholars to work on problems of human fertility. Bringing such scientists together at a few centers would create a highly stimulating atmosphere and bring a new sense of urgency to our appreciation of world population problems. The work of such laboratories would attract public
