What countries created a law limiting the number of children per family to control the nation population?

China is the most notable example, having implemented the One-Child Policy in 1979 to control its population growth, which was later relaxed to a Two-Child Policy in 2015. India also introduced measures in certain states to encourage smaller families, though it has not enforced a nationwide law. In recent years, countries like Vietnam and Iran have implemented family planning programs to manage population growth, but with varying degrees of enforcement and public acceptance.
