ABSTRACT
The International Biological Programme, which operated in the decade from 1964 to 1974, was constituted to survey aspects of human welfare. Because one of the important indexes of the health status of a community or country is the growth of its children, one of the Programme's research efforts was directed at a worldwide investigation of these variables. The Programme's report can serve as a model of the comparative study of development (see Eveleth & Tanner, 1976).
