China has ended its one-child policy(政策) in 2015. The government announced it would now allow all couples to have two children. The one-child policy was a population control measure that was introduced in 1979. Policy makers hoped to control the country’s population to avoid high rates of poverty(贫穷).

The new two-child policy should give a huge economic(经济) push for China and prevent China from becoming an ageing society. China’s labor(劳动力) force peaked at 940 million in 2012. This fell to 930 million in 2014 and is expected to fall by 29 million by 2020. Predictions are that there will be an average of 2.5 million extra newborns per year. This will provide more workers and an extra $11.8 billion in annual GDP. The new policy will affect around 100 million people.
