World is mostly looking at China after its one-child-policy as the greatest example.
China's one-child policy was a success. They were able to put on the brakes during the period between health care getting good and standard of living going up, which is when population goes way up. India didn't do that, and their population shot up beyond the country's water supply. France is just leveling off. Japan is in actual decline.
