Science Alert:
A deep-rooted preference for sons over daughters has skewed the world's sex ratios more than we thought.Males are normally born at a rate of 105 males birth for every 100 female births. It evens out over the next 20 years or so because males die at a higher rate before maturity than females. But now females die in the womb at a much higher rate than males.
A massive five-year analysis has found that since 1970, sex-selective abortions in a dozen countries have resulted in 23 million 'missing' girls.
These are women that were never born, and yet today, their absence is palpable, especially in eastern Europe and Asia. In China alone, the study found there were 11.9 million missing females, and India had 10.6 million.
After years of a controversial single-child policy, China was unsurprisingly at the top. At one point in 2005, the authors found that the most populated country in the world actually had a male birth ratio of 118.So what do you do with tens of millions of young, virile and frankly horny young men who have zero chance of getting married because there are zero women available to marry them? Maybe more importantly, what do those men do? The question practically answers itself.
Today, in China and India, men outnumber women by 70 million, and it's causing an epidemic of loneliness, a distortion of labour markets, and an increase in female trafficking and prostitution.
Not only that, but those nations will lose one of the natural restraints of going to war that inhibited prior generations, though of course not always successfully: the fear of massive casualties. China could invade Taiwan and if it lost three million men conquering the country, so what? It still has 30 or 40 million more that can die invading somewhere else.

In parts of China and India, there will be a 12–15% excess of young men. These men will remain single and will be unable to have families, in societies where marriage is regarded as virtually universal and social status and acceptance depend, in large part, on being married and creating a new family (45).It will get worse until 2050, when the number of "missing girls" will peak at present trend lines.
An additional problem is that many of these men are rural peasants of low socioeconomic class and with limited education (46). When there is a shortage of women in the marriage market, the women can “marry up,” inevitably leaving the least desirable men with no marriage prospects (47). For example, in China 94% of all unmarried people age 28–49 are male and 97% of them have not completed high school (48). So, in many communities today there are growing numbers of young men in the lower echelons of society who are marginalized because of lack of family prospects and who have little outlet for sexual energy. A number of commentators predict that this situation will lead to increased levels of antisocial behavior and violence and will ultimately present a threat to the stability and security of society (31, 45–49).
There is some empirical evidence to fear such a scenario. Gender is a well-established individual-level correlate of crime, and especially violent crime (50). It is a consistent finding across cultures that an overwhelming percentage of violent crime is perpetrated by young, unmarried, low-status males (50–52). In India, a study carried out between 1980 and 1982 showed a strong correlation between homicide rates in individual states across the country and the sex ratio in those states, after controlling for potential confounders such as urbanization and poverty (53). The authors concluded that there was a clear link between sex ratio and violence as a whole, not just violence against women as might be assumed when there is a shortage of females. These analyses were repeated by Hudson and Den Boer (46), who showed that the relationship between sex ratio and murder rates at the level of the Indian state persisted through the late 1990s. In China, young male migrant workers are thought to be responsible for a disproportionate amount of urban crime, especially violent crime. It is reported that migrants account for 50% of all criminal cases in the major receiving cities for migrants, with some cities reporting up to 80% (54).
There is also evidence that, when single young men congregate, the potential for more organized aggression is likely to increase substantially (45, 53). Hudson and Den Boer, in their provocative writings on this subject (45, 46), go further, predicting that these men are likely to be attracted to military or military-type organizations, with the potential to be a trigger for large-scale domestic and international violence. With 40% of the world's population living in China and India, the authors argue that the sex imbalance could impact regional and global security, especially because the surrounding countries of Pakistan, Taiwan, Nepal, and Bangladesh also have high sex ratios.
While the majority of parents in United States do not practice sex-selective abortion, there is certainly a trend toward male preference. According to a 2011 Gallup poll, if they were only allowed to have one child, 40% of respondents said they would prefer a boy, while only 28% preferred a girl.[107] When told about prenatal sex selection techniques such as sperm sorting and in vitro fertilization embryo selection, 40% of Americans surveyed thought that picking embryos by sex was an acceptable manifestation of reproductive rights.[108] These selecting techniques are available at about half of American fertility clinics, as of 2006.[109]But I guess that's okay because abortion on demand is a woman's sacred right. Kidnapping young girls and women into sex-trafficking rings for unmarriageable men? That's a crime. That it occurs at increased numbers because of abortion does not matter - because abortion? That's medical care.
