By means of coercion such as loss of maternal and child health benefits or educational assistance, tax benefits, or the imposition of penalties for going beyond a given number of children, governments deny their citizens the right to procreate. Subtle tactics such as antinatalist propaganda campaigns and/or quotas assigned to family planning workers are also employed.
China's One Child Policy is an extreme example of governmental intervention into procreation. Women required a permit from their local communist party official in order to become legally pregnant. These permits were strictly rationed in each area, and the couple observed to see they did not become pregnant before their permitted time. Any woman who became pregnant without permission was subjected to harassment and even deprived of her liberty until the pregnancy was aborted.
