2016 ushers in change in China: The end of its one-child policy. Faced with a demographic crisis, the nation is now allowing couples to have two babies.

Details from the Asia bureau and FOX's Alastair Wanklyn:

It was announced three months ago and is now in effect: Chinese couples are free to have up to two children, as Beijing calculates its one-child policy will create an aging, shrinking population a few decades from now.

Churches and human rights campaigners have pointed out the human cost of the nearly four decades of prohibition: An estimated 400-million babies lost, including through forced abortions.
