As for the one-child policy, data released by China’s health ministry in 2013 indicate that from 1971 to 2012, 336 million abortions – more than the entire US population – were carried out in registered facilities alone. (Though the one-child policy was not introduced until about 1979, other family-planning policies were already in place at the time.)
至于一胎政策，据中国卫生部门2013年公布的数据看，从1971—2012年，光是注册家庭就发生了3.36亿起堕胎——比美国人口总数还要大。（一胎政策直到1979年左右开始实施，但当时其他计划生育政策已经存在。）
