"The one-child policy officially translated as "family planning policy") is the population control policy of the People's Republic of China (PRC). It restricts urban couples to only one child, while allowing additional children in several cases, including twins, rural couples, ethnic minorities, and couples who are both only children themselves. In 2007, according to a spokesperson of the Committee on the One-Child Policy, approximately 35.9% of China's population was subject to a one-child restriction. The Special Administrative Regions of Hong Kong and Macau are exempt from the policy. Also exempt from this law are foreigners living in China."
