In a survey carried out in 1969, research in the area of "biology and medical sciences" corresponded to one-third of all the ongoing projects and occupied the leading position with 926 projects. It was followed by agriculture (674 projects), social sciences (349 projects), technology (234 projects), earth sciences (190 projects) and chemistry (152 projects). However, concerning the financial aid granted for the development of these research projects, the portion allotted to the area of health was considerably more modest than was that allotted to the other areas. (1) According to the Conselho Nacional de Pesquisa e Desenvolvimento (CNPq, National Council on Research and Development), after three decades, biological and health sciences still account for the greatest number of lines of research (21,371), corresponding to 30% of the lines of research pursued in all of the broad areas of knowledge.
