Countries with anti-natalist policies are China, India, and Uzbekistan.
Explanation:
The countries can roughly be divided into having pro-natalist or anti-natalist policies. The decision as to which of these two policies is implement depends on the area available, population size, increase or decrease rates, and available resources. Some countries have been swinging between the two policies, setting one for a decade and than turning to the other for a decade, returning to the previous one, and again to the other one, like in the case of Iran.
Some countries that have anti-natalist policies are:
China has such policy for several decades now. Initially it was only one child per family that was allowed, and only few years ago it was allowed for two children by family. The reason for this was the rapid increase of the already huge population and the fear that it will lead to economic and social collapse on the long run. The same problem has been the case in India as well. Even though there are policies that are anti-natalist, the people don't seem to apply to them, though the birthrates have been steadily dropping recently due to the development and gradual increase of the standard of living. Uzbekistan, on the other hand, is castrating the women after they have two children. The reason for this is that the country doesn't have enough resources so they desperately are trying to not become overpopulated and collapse.
