One-Child Policy

In 2013, Deputy Director Wang Peian of the National Health and Family Planning Commission said that "China's population will not grow substantially in the short term". 

The one child policy, a part of the family planning policy, was a population control policy of China which was introduced between 1978 and 1980 and began to be formally phased out in 2015. 

The policy allowed many exceptions and ethnic minorities were exempt.


During the period of Mao Zedong's leadership in China, the crude birth rate fell from 37 to 20 per thousand, infant mortality declined from 227/1000 births in 1949 to 53/1000 in 1981, and life expectancy dramatically increased from around 35 years in 1948 to 66 years in 1976.
         Until the 1960s, the government encouraged families to have as many children as possible because of Mao's belief that population growth empowered the country, preventing the emergence of family planning programs earlier in China's development. The population grew from around 540 million in 1949 to 940 million in 1976. Beginning in 1970, citizens were encouraged to marry at later ages and have only two children.


The sex ratio at birth (between male and female births) in mainland China reached 117:100 and remained steady between 2000 and 2013, substantially higher than the natural baseline, which ranges between 103:100 and 107:100. It had risen from 108:100 in 1981—at the boundary of the natural baseline—to 111:100 in 1990.

The one-child policy was originally designed to be a one-generation policy. It was enforced at the provincial level and enforcement varied; some provinces had relaxed the restrictions. After Henan
 loosened the requirement, the majority of provinces and cities permitted two parents who were 'only children' themselves to have two children.
                 Beginning in 1987, official policy granted local officials the flexibility to make exceptions and allow second children in the case of "practical difficulties" (such as cases in which the father is a disabled serviceman) or when both parents are single children, and some provinces had other exemptions worked into their policies as well. Second children were sometimes subject to birth spacing (usually 3 or 4 years). Children born in overseas countries were not counted under the policy if they do not obtainChinese citizenship. Chinese citizens returning from abroad were allowed to have a second child.

Adoption

A roadside sign in rural Sichuan: "It is forbidden to discriminate against, mistreat or abandon baby girls."

The one child policy of China has made it more expensive for parents with children to adopt, which may have had an effect upon the numbers of children living in state-sponsored orphanages. However, in the 1980s and early 1990s, poor care and high mortality rates in some state institutions generated intense international pressure for reform.

          In the 1980s, adoptions accounted for half of the so-called "missing girls". Through the 1980s, as the one-child policy came into force, parents who desired a son but had a daughter often failed to report or delayed reporting female births to the authorities. Some parents may have offered up their daughters for formal or informal adoption. A majority of children who went through formal adoption in China in the later 1980s were girls, and the proportion who were girls increased over time.

Four-two-one" problem

As the first generation of law-enforced only-children came of age for becoming parents themselves, one adult child was left with having to provide support for his or her two parents and four grandparents. Called the "4-2-1 Problem", this leaves the older generations with increased chances of dependency on retirement funds or charity in order to receive support.

If, for any reason, the single child is unable to care for their older adult relatives, the oldest generations would face a lack of resources and necessities. In response to such an issue, all provinces have decided that couples are allowed to have two children if both parents were only children themselves.

Unregistered children

Heihaizi (Chinese: 黑孩子; pinyin: hēiháizi) or "black child" is a term applied in China. The term denotes children born outside the One child policy, or generally children who are not registered in the Chinese national household registration system.

Being excluded from the family register (in effect, a birth certificate), they do not legally exist and as a result cannot access most public services, such as education and health care, and do not receive protection under the law.
