Wifeless men Since prenatal sex determination became available in the mid-1980s, China has witnessed large cohorts of surplus males who were born at that time and are now of marriageable age. The estimated excess number of males was 2.3, 2.7, and 2.1 million in the years 2011, 2012, and 2013 respectively. On occasion, families would adopt female infants as a way to secure a future bride for their sons. These girls would be raised by their adoptive families to learn how to care for and serve their future families. Since women tend to marry men in higher socioeconomic groups than their own, the shortage of women in the marriage market will leave the least desirable, the poorest, and uneducated men with no marriage prospects. These wifeless men's lives could be seriously influenced by how the public view them.
Propensity to violence The future social effect of the
guang gun remains a topic of concern. The majority of Chinese think that the
guang gun are likely to affect criminal behavior. An early commentator predicted that, "such sexual crimes as forced marriages, girls stolen for wives, bigamy, visiting prostitutes, rape, adultery... homosexuality... and weird sexual habits appear to be unavoidable." Conversely, marriage reduces male criminality. Families in more rural parts of China resort to buying and selling kidnapped brides and forcing them to bear their sons' children. Although prostitution is illegal in China, there may appear expansion of female sex workers to meet increased demand of wifeless men. Based on a sample of 506 migrants, about half of them had
multiple sex partners and 89% of these migrants did not use condoms. Initially, China's goal was to get the fertility rate down to the replacement level of 2.1 births per women, but the fertility rate continued to fall and it is now at 1.09 births per women. Demographers warn that fertility rates this low can hinder the development of a country and China has started to change their policies in order to increase their fertility rate and avoid any future adversity. In 2015, the Chinese government decided to change the one-child policy and implemented a
two-child policy. Some researchers argue that son preference along with the one-child policy are one of the many contributing factors to an imbalanced sex ratio that has left millions of unmarried men unable to marry and start a family. Scholars and journalists from outside of China argue that simply dropping the one-child policy will help raise the number of girls born into China and thus raise the future fertility rate. Even though the two-child policy is now in act, couples are still choosing to remain a single-child household due to expensive childcare and women's increasing hesitance to leave their careers to raise a family.
Aging population Large numbers of missing women also contribute to the problem of
population ageing in China. Since females and males together are responsible for the social reproduction, People over 65 in China will account for 15% of the population between 2025 and 2030, while those over 60 will account for a quarter of the population in 2050. This rapidly increasing elderly population will also aggravate the social burden of the pension insurance system.
Economic effects The long-term economic outcomes of China's missing women phenomenon are a source of diverse debate. Some scholars argue that, in the short term, declining fertility rates create an advantageous ratio of abundant producers to smaller populations who rely on that productivity (children, infants, pregnant women etc.). However, others argue that over time, as economically productive populations age, the number of dependents decreases and ratios tilt the other way. == Reactions ==
