Passionate and troubling, this study by Columbia University historian Connelly (A Diplomatic Revolution
) tells the story of the 20th-century international movement to control population, which he sees as an oppressive movement that failed to deliver the promised economic and environmental results. According to Connelly, some proponents of the movement thought it was the key to women's health and well-being; others saw it as a way to eliminate the poor population; still others believed it would protect the environment. But Connelly also shows how larger economic and social contexts shaped the movement. For example, during the 1930s international Depression, ordinary people increasingly felt that couples planning families should focus on financial considerations; at the same time, as the state offered increased economic aid, it became acceptable to believe the state should also have a role in regulating reproduction. Far from disinterested, Connelly challenges many of the population control movement's claims: to those who argue that the slowed population growth in Asia has helped save the planet, Connelly notes tartly that “if Asians have 2.1 children, but also air conditioning and automobiles, they will have a much greater impact on the global ecosystem than a billion more subsistence farmers.” Ambitious, exhaustively researched and clearly written, this is a highly important book. 22 b&w illus.
