Instituted in 1979 as a temporary measure to limit population growth, Chinas one child policy remains in force today and is likely to continue for another decade. Chinas population control policy has attracted criticism because of the manner in which it is enforced, and also because of its social repercussions. Supporters of the Chinese governments policy consider it a necessary measure to curb extremeoverpopulation, which has resulted in a reduction of an estimated 300 million people in its first twenty years. Not only is a reduced population environmentally beneficial, it also increases Chinas per capita gross domestic product. The one-child policy has led to a disparate ratio of males to females  with abortion, abandonment and infanticide of female infants resulting from a cultural preference for sons. Furthermore,Draconian measures such as forced sterilization are strongly opposed by critics as a violation of human reproduction rights. The one-child policy is enforced strictly in urban areas, whereas in provincial regions fines are imposed on families with more than one child. There are also exceptions to the rules  for example, ethnic minorities. A rule also allows couples without siblings to have two children  a provision which applies to millions of sibling-free adults now of child-bearing age.
