Summary

From the 1950s to the 1970s, numerous academics and non-governmental organizations based in the United States generated alarm about political and ecological threats posed by human population growth. During the first half of the 20th century, improvements in nutrition, sanitation, and medical therapies had dramatically reduced infant mortality and contributed to increased life expectancy in many parts of the world. In the context of the Cold War, many leaders of Western industrialized nations viewed the rapid growth of poor Asian, African, and Latin American populations as a potential source of political instability. They feared that these poor masses would become fodder for revolutionary political movements, particularly communism. Combined with eugenicist views rooted in colonial racism, new understanding of ecological systems, and growing concern about overtaxing earth’s resources, these fears led many American and European scholars and activists to promote population reduction in the newly designated “Third World.” In Latin America, such efforts to curb human increase were met with skepticism or outright opposition by both Catholic Church leaders and many left-wing nationalists who saw the promotion of birth control as a form of racist imperialism. Although some physicians and even liberal priests viewed decreasing family size as important for public health and family welfare, the involvement of North American capitalists (such as the Rockefellers), U.S. government agencies, and former eugenicists in efforts to distribute contraceptive technologies made them deeply suspect in the eyes of many Latin Americans.
