In the 1950s, when the more blatant evils of artificial baby milk had been eliminated, surveys seemed to suggest that breast-feeding was not particularly beneficial, but twenty years later authorities definitely knew they were wrong. Many baby foods were harmful because concentrations of salts and energy sources were too high. Some parents were making feeds more concentrated than the manufacturer’s recommendation. Public health authorities now strongly endorse breast-feeding for the entire first year of life, and public enthusiasm has revived substantially, although better artificial baby foods are available.
Before 1959, NIH was expressly forbidden to support birth control research, probably because of archaic state and federal laws. 55 In an important ruling in the case of Griswold v. S. Supreme Court declared such laws unconstitutional; it later ruled on other laws relating to unmarried couples. Meanwhile, as the world birth rate accelerated to a doubling time of just forty years, organisations such as the World Health Organisation (WHO) were increasingly convinced that every aspect of population policy needed research.
By the end of the nineteenth century, human reproductive behaviour was again adapting to new circumstances. Starting in France during the years of revolution and then in the rest of Europe and North America, the birth rate began to fall. A trend that began amongst the highest strata of society spread steadily to working-class families. 7,29 Demographers suppose that the decline in fertility was precipitated by parents’ growing optimism that their children would survive. Analysis of population trends in different countries over the last 150 years suggests that a decline in infant mortality is followed by a decline in the birth rate ten or twenty years later.
