Additionally or alternativelyit could adopt more punitive measures for women seeking sex-selective abortions. In a sense, this relaxation of policy institutionalized a cultural value of son preference. Inthe UN estimated that the mean age at first marriage was In growing stable populations with a young age structurean unbalanced SRB may be offset if men marry women from much younger and larger cohorts than themselves, and this effect would increase the greater the age gap.
This effect is larger the later men marry and the wider the age gap between spouses.
In growing populations, younger cohorts are generally larger than older cohorts. From to the total fertility rate TFR fell from almost 6 children per woman to only 2 ibid. China recently announced that the National Population and Family Planning Commission would maintain its one-child policy Xinhua Newsdespite criticism by some experts who maintain that the policy is unnecessary and contributes to population aging and unbalanced sex ratios The Economist The children born immediately after the initiation of the one-child policy are now reaching marriageable ages and inheriting the consequences of the skewed sex ratio at birth.
In China, the age gap in marriage partners is even lower. Specifically, we describe their typical ranges across world populations and their current levels in China. We do not simulate the effects of policy directions to influence migration. The sex ratio at birth SRB lies in the range from about 1. This provides a more realistic assessment of the scope of the problem for China in the near future. This suggests that, if Chinese men continue to marry younger women, the projected population decline and shifting age structure are likely to exacerbate the problem of marriage for Chinese men.
Surplus chinese men: demographic determinants of the sex ratio at marriageable ages in china
The government could do this indirectly through efforts to raise the status of women in Chinese society. If Chinese men began to marry women who were about the same age as themselves, this would increase the SRM by. The spousal age gap varies considerably across countries and contexts. The average ratio across countries was. The opposite is true in declining populations.
These formulas can be used to gauge the long-run effects that future policies would have on an existing population. A report issued by the World Health Organization produced life tables for countries Lopez et al.
The SRB is closely associated with the SRM when the growth rate, age gap between marriage partners, and mortality ratio are held constant at their current levels in China. Thus, an uneven sex ratio at birth could possibly even out by young adulthood as a result of differential mortality. This is evident in stable population models.
Women in China report they would prefer to have two children, a boy and a girl Riley As this preference is accommodated by relaxing the one-child policy, it could lead to a more balanced sex ratio both at birth and at marriage. When these expressions are substituted into 1 :. Could new family planning or marriage policies reverse or lessen this problem? The age gap is unlikely to change to this extent in China, but if we consider a more realistic change from 2 to 4 years, the SRM would decrease by.
Despite this steep fertility decline, by the Chinese government became convinced that more extreme measures would have to be taken to curtail population growth Greenhalgh The one-child policy resulted in a further drop in fertility. We elaborate on each factor below. Then, to assess the sensitivity of SRM to each factor, we use 2 to simulate for a stable population how much SRM could change given an adjustment in each of the factors across their normally observed ranges.
In sum, four demographic factors have the potential to alter the SRM. When comparing across normally observed ranges, SRB, population growth, the age gap between spouses, chinese girls looking for New Jersey husbands the sex ratio in survival could change SRM by as much as. How long will the effects of the unbalanced sex ratio persist in China? In shrinking populations, younger cohorts are smaller than older cohorts, which compounds the problem of an unbalanced SRB. If we consider a narrower range of population growth rates that could be realistically expected for China, a decline from the current rate 0.
Try out PMC Labs and tell us what you think. One such consequence is an unbalanced sex ratio at birth, with many more boys born in each generation than girls. Since the early years the policy has been relaxed for some groups, including ethnic minorities and some families in rural areas. If China conformed to the assumptions of the stable population model, SRM could decrease as much as.
Males tend to have higher mortality than females during younger ages, resulting in a sex ratio of approximately 1. Before China underwent its rapid fertility decline in the early s, the birth rate was very high and the chance of a family having at least one son was correspondingly high Pison When a woman has six children, the probability that at least one of them will be male is greater than 98 percent.
We produce several alternative population projections for China in which we test the effect of the three possible interventions identified in our stable population equation. China began experimenting with fertility policy almost 30 years before it introduced the one-child policy Tien et al. It exceeds 1. Finally, it could also offer incentives for couples to have female children, similar to the existing Care for Girls program Shang, Li, and Feldman Another policy direction is to relax fertility restrictions, a policy option apparently now strengthening.
Notably, the city of Yicheng in Hubei province was exempted from the one-child policy in and has biologically normal sex ratios at birth in addition to low fertility rates Das Gupta, Ebenstein, and Sharygin However, Chinese official Wang Feng was quick to clarify that there would be no other changes in the one-child policy Xinhua News Regardless, experts on China speculated that scrutiny of the one-child policy is increasing and that this restructuring may precede elimination of the policy altogether The Economist The government policy limiting most couples to one child and a strong preference for sons appear to have driven the large sex imbalance at birth.
Poston and Glover estimated that in What demographic changes would result in the largest decrease in the sex ratio at marriageable ages? The example of Yicheng, mentioned earlier, offers support for that expectation.
The population growth rate r affects the sex ratio at marriageable age because it shapes age structure. If mortality declined faster for women, this could help offset the uneven SRB. As the mortality gap between men and women shifts from the lowest. In a stable population growing at rate r where men aged x at time t PM t,x marry women at age y PF t,ythe sex ratio at marriageable age SRM at time t is:. If we consider a range that is more realistic for China, from the current ratio 1. An uneven age structure can be especially problematic for men if they tend to marry younger women and if their birth cohort is larger than the cohorts born just after them, as was the case for Chinese men who were 15—19 in and who will be entering the marriage market between and While researchers agree that the sex imbalance is a problem, few address ways in which China could devise policies to address it.
In particular, if women were allowed to have more children, they may be less likely to seek sex-selective abortions. Thus, for men aged x :.
China has banned this practice since Shang, Li, and Feldman Although the degree to which sex-selective abortions are practiced is debated Eberstadt ; Chu ; Banisterscholars agree that it probably occurs in China as well as many other East Asian countries with a son preference Hull ; Johansson and Nygren ; Chu ; Banister While sex imbalances at birth remain with cohorts as they age, several other demographic factors influence the sex ratio at marriageable age and may therefore reduce or, in some circumstances, exacerbate the influence of an unbalanced sex ratio at birth.
This means that in China, an unbalanced SRB is not offset by sex differentials in mortality.

A sex ratio of about males per females at birth is considered biologically normal. Roughly 94 percent of Chinese men and women survive to age25, so further reductions in mortality in China are theoretically possible. To answer these questions, we first develop a stable population model of the sex ratio at marriageable ages. Mortality tends to be higher for men than women. The Chinese prefer sons to daughters for several reasons: to carry on a family name, to provide support for aging parents, and to assist parents in household production Bhattacharjya et al.
Casterline, Williams, and McDonald analyzed the age difference between spouses across 28 developing countries in the s and s, and found median gaps as high as 9. Second, we compare population projections with alternative underlying assumptions about the sex ratio at birth, population growth, and the age gap at marriage. The male-to-female ratio in survival to age 25 varies considerably, ranging from. Learn More.
We calculated the ratio of survival to age 25 for men versus women for each country. We develop formulas to show how altering the sex ratio at birth, population growth, and the age gap between marriage partners would influence the sex ratio at marriageable ages in a stable population. Greenhalgh and Li ,pp. Since men tend to marry younger women, a youthful age structure helps to offset the effects of an unbalanced SRB. That is, if there were excess men because of a high SRB, men may still be able to find spouses among the larger cohorts of younger women.
The rate is currently 0.
These include policies that target 1 the sex ratio at birth, 2 population growth through increased fertility, and 3 the age gap between marriage partners. Sincethe Chinese government through its one-child policy has limited the of children most citizens can have. From 2under these assumptions, an increase in SRB from normal levels 1. Inthe Chinese government eased the one-child policy for rural couples, allowing them to have two children.
