Not sure exactly what you're trying to ask but I can provide some examples from previous years.
The one-child policy came into affect in China in 1980, and ended in 2016. Families all over the country were limited to having only one child due to reduce the growth of overpopulation, which the government described as "growing too rapidly". If parents had more than one child, the child would not be penalised, including a mother that gave birth to twins. If you had more than one child, the child was likely taken away. Parents were fined, forced to have abortions and lost their jobs. Today China is limited to a three-child policy, but most families still do not want to have more than one kid, often because they fear for the future. China's birth rate is still decreasing.
I hope this information helps with your guess for the future.
