China’s parliament gave the clearest signal yet that the leadership is moving to end limits on the number of children families can have by striking “family planning” policies from the latest draft of a sweeping civil code slated for adoption in 2020. The Communist Party began enforcing a one-child policy in 1979 to slow population growth. The limit was raised to two children in 2016, but births have not increased as much as forecast since the policy was loosened.
