Third, and most policy-relevant of all, the reverse momentum built up by the hundreds of millions of births already averted would carry forward to avert their descendants even if the government lifted the program immediately. And if the government did so, without having to spend a single additional yuan on the birth planning program, it could still claim an averted population by 2060 far in excess of the 400 million that they had asserted. In fact, paradoxically, although any fertility uptick following a policy repeal would have reduced estimates of births averted directly resulting from policy, that reduction would have been largely offset by increased estimates of the averted descendants who would have been born under higher assumed fertility.
