China's Missing Women: The Impact of Son Preference and Population Policy
For decades, China has faced a significant demographic challenge known as the phenomenon of missing women. This term refers to the millions of females who are absent from the population due to a combination of cultural preferences and restrictive state policies. The intersection of traditional son preference and the one-child policy created a environment where female children were often undervalued, leading to systemic discrimination from before birth through early childhood.
The causes of this imbalance are multifaceted, ranging from medical interventions and neglect to administrative underreporting. By examining these drivers, we can understand how social and political pressures skewed the natural biological balance of the population.

Key Facts
- Sex Ratio Imbalance: China's sex ratio at birth rose from 111 in 1990 to 119 in 2010.
- Scale of Loss: The WHO estimated in 1997 that over 50 million women were "missing" due to institutionalized killing and neglect.
- Prenatal Impact: Approximately 37-45% of missing women may have been lost prior to birth via sex-selective abortion.
- Contraceptive Prevalence: 84.6% of married women in China use contraception, one of the highest rates globally.
- Registration Gaps: Millions of girls were not registered at birth to avoid policy penalties, often appearing in data only after age ten.
The Role of Sex-Selective Abortion
The availability of prenatal sex-identifying technology, combined with a strong cultural preference for sons, led to a rise in sex-selective abortions. Although Chinese law prohibits testing the gender of a fetus, some families bypassed these restrictions by sending blood samples to Hong Kong, where such practices were not prohibited.
This trend has significantly skewed the sex ratio. According to China Statistics Press 2013, the sex ratio at birth followed an upward trend: 111 in 1990, 117 in 2001, 121 in 2005, and 119 in 2010. While some argue that this access reduces post-birth abandonment and empowers mothers to gain familial recognition by producing a son, the long-term social consequences are severe. A shortage of women can reduce civic power for females and lead to increased violence, kidnappings, and forced marriages in regions where marriage is tied to social advancement.
Female Infanticide and Abandonment
Female infanticide—the murder of baby girls—has occurred throughout Chinese history, often peaking during times of crisis. For example, during the Great Chinese Famine (1959–1961), families used infanticide to conserve resources. The one-child policy further intensified this practice, as parents sought to ensure their single allowed child was a boy.
In some rural areas, researchers found that up to half of all newborns were killed by their families. This cultural preference is rooted in the tradition that daughters "marry out," while sons remain to provide financial support. This disparity is reflected in historical texts like the Quan Han Shu, which noted that daughters were often not celebrated at birth.
Beyond infanticide, abandonment became a common occurrence. In rural areas, parents often left baby girls in public places or dustbins to be found by others. In state-owned orphanages, over 95% of the infants are healthy baby girls, many of whom died shortly after arrival due to poor conditions and health neglect.

Health Neglect and Maternal Care
Discrimination extends beyond birth through the withholding of nutrition and healthcare. This neglect leads to a female infant mortality rate that outpaces that of males, despite the biological advantage girls typically have in their first year of life.
Adult women also suffer from early-life neglect. A critical example is zuò yuèzi (坐月子), the traditional 30 to 40-day postnatal convalescence period. When rural women are forced to perform heavy farm work during this time instead of resting, they face higher risks of health complications and premature death.
Contraceptive Use and Reproductive Health
To manage population growth, the Chinese government heavily promoted contraceptive use. This resulted in China having one of the highest contraceptive prevalence rates in the world at 84.6%, surpassing the United States (78.6%) and Japan (54.3%).
While these services provided women with birth control options, they primarily benefited married women. Unmarried youth often fell into a gap of unintended pregnancies. However, shifting social attitudes are evident; a 2015 Renmin University survey found that over half of respondents now find premarital sex acceptable, signaling a move away from traditional views on sexual health.
Non-Registration and Data Discrepancies
Not all "missing" women were deceased; many were simply unregistered. To avoid penalties for exceeding birth quotas and to save "slots" for future sons, rural parents and village leaders often underreported the birth of girls.
This created a statistical anomaly where females "appeared" in the census after the age of ten. For the 1990 cohort, the sex ratio was 111 at birth but dropped to 103 by 2010, as 4.8 million late registrations occurred—including 900,000 more females than males. Similar patterns of 550,000 to 950,000 unregistered females were found in other cohorts.
| Factor | Primary Mechanism | Key Impact/Statistic |
|---|---|---|
| Sex-Selective Abortion | Prenatal gender testing and termination | 37-45% of missing women lost pre-birth |
| Female Infanticide | Direct killing or neglect of newborns | WHO estimated 50M+ missing women (1997) |
| Abandonment | Leaving infants in public places/orphanages | >95% of state orphanage babies are girls |
| Health Neglect | Malnutrition and lack of medical care | Female infant mortality exceeds male rate |
| Non-Registration | Underreporting births to avoid penalties | Millions of girls registered only after age 10 |
Frequently Asked Questions
What is the "missing women" phenomenon in China?
It refers to the significant shortfall of females in the population caused by sex-selective abortion, female infanticide, neglect, and the non-registration of baby girls, largely driven by son preference and the one-child policy.
How did the one-child policy affect the sex ratio?
The policy limited parents to one child, which intensified the desire for that child to be a son. This led to an increase in sex-selective abortions and infanticide, raising the sex ratio at birth from 111 in 1990 to a peak of 121 in 2005.
Why were some girls not registered at birth?
Rural parents often did not register daughters to avoid paying penalties for over-quota children and to keep the possibility open for having a son later without violating policy limits.
What is zuò yuèzi and why is it relevant?
Zuò yuèzi is a traditional 30 to 40-day postnatal recovery period for mothers. When this period is ignored—such as when rural women return to heavy farm work immediately—it increases the risk of long-term health complications and early death.
Does China have high rates of contraceptive use?
Yes, China has one of the highest rates globally, with 84.6% of married women using contraception, which is higher than the rates in the United States and Japan.
