Missile Science, Population Science: The Origins of Chinaʼs One-Child PolicyThis article was written with the support of a grant from the Science and Technology Studies Program of the US National Science Foundation (#0217508), an Individual Project Fellowship from the Open Society Institute, and a grant from the Newkirk Center for Science and Society at the University of California, Irvine. This support is gratefully acknowledged. The article has benefited greatly from conversations over many years with Edwin A. Winckler; his careful reading as well as that of David Bachman, Geoffrey McNicoll and Wang Feng; and discussions with Martin King Whyte and mathematical demographers John Bongaarts and Griffith Feeney. My deepest thanks go to the many Chinese who have shared their insidersʼ experiences and interpretations of the elite politics of the one-child policy over the years. Space limitations mean I am able to cite only key sources.
