When Chairman Mao took power in the late 04s, he was warned by Chinese scholars that China was in danger of being overpopulated if it kept on it's current growth trend. They were growing faster than their infrastructure or their ability to grow food. Their numbers were quite compelling and he actually started off his reign with fairly strict measures to encourage low birth rates.
Later in the 1950s, he believed that the USSR and the West were going to engage in an atomic war, and likely wipe each other out. He also concluded that if China was populous enough, it would survive any war by numbers alone, and would be able to resettle the remaining world after the dust settled.
Because of this, he pushed off a major propaganda campaign, calling for huge families as necessary and patriotic. This lead to the skyrocketing population increase that Chinese scholars were terrified of.
Sure enough, after Mao's death, the numbers were pretty bleak. China was heading towards mass starvation, inescapable poverty and social collapse. There just weren't enough resources in the country to support a culture where families just kept having kids until they has a boy or two. They had to do something to stabilize the numbers, and they did.
While there is some instances of sterilization and forced abortion, as a percentage that's extremely rare. The actual mechanism for enforcing the 1 child policy is social pressure and a hefty tax on any children over the first.
I spent some time in China, back when I was in the Army, and I spoke to a number of people about this. They uniformly don't like the 1 child policy, but also concede that Mao's policies had left no choice. It was either 1 child or starve.
Whereas our policy, on the other hand, it to seize the healthcare industry and then ration it by age, so that "wage earners" don't have to support as many retired people.
