Look at China.
China has never had a universal policy of one-child-per couple. There are so many exceptions that only about a third of the population is subject to the policy.
However, had they done so, their population would shrink. 1 child for every female is not enough to maintain population levels, much less grow them. It's estimated that the population replacement rate in developed countries is ~2.1 children per female (that is, on average, each female would have to have, on average, 2.1 children to maintain population levels).
