In this new environment, more women are hesitating to commit, knowing that the penalty of being ‘left on the shelf’ is much less than before. Many, in fact, are playing the market and postponing marriage as late as possible. One result is a rising age of first marriage—almost 30 in most Western countries.
Because people are getting married later, the ratio of single men to single women under 30 looks almost balanced. This near-parity has lulled some writers, like Glowsky (2007), into thinking that intense competition for women is a problem only for middle-aged men. Actually, single men under 30 face even fiercer competition. Using age-preference data, Ni Bhrolchain and Sigle-Rushton (2005, pp. 44, 46) have estimated that two single men are competing for each single woman at the youngest ages:
… Among men, average partner supply is 0.4 at age 17, reaches and goes above 1.0 at around 30 in the US and at 45 in England and Wales (though also, briefly, at age 30) and then rises to 2.0 (US) and 1.6 (E&W) by age 60. On these estimates, a 50-year-old American man had around the same number of potential partners as an American woman of 20 in 1990 ....
… In pure demographic terms, then, and taking these figures at face value, men and women of the same age encounter quite dissimilar levels of partner supply at most ages. In 1990-91, average availability for women far exceeds that for men at younger ages and the reverse is true at older ages. In both countries [United States and Great Britain] in 1990-91, unmarried women aged 20-24 had between 34% and 163% more potential partners on average than did men, and those aged 25-29 between 8% and 28% more.
It might be argued that these estimates overstate the gender imbalance. After all, some young men are uninterested in female companionship because they’re asexual, homosexual, or psychologically immature. This objection was tested by Ni Bhrolchain and Sigle-Rushton (2005, p. 53) through a survey of dating agency clients:
If men experience partner shortages at the prime ages of male marriage, we would expect to find young men over-represented in the dating agency client population. This is indeed the case. Between ages 21 and 40 the age-specific sex ratio among Dateline clients is between 1.4 and 2.6, compared with sex ratios of between 1.1 and 1.3 among the unmarried in England and Wales in 1996.
The new ‘seller’s market’ contrasts with what young men used to face as recently as the early 1970s. Yet this change in fortune has triggered few alarm bells among the commentariat. How come? One reason is that many people blame the sexual revolution of the 1960s on that era’s low ratio of single men to single women. The argument is that a surplus of single women makes men sexually irresponsible. To ensure stable families, we therefore need a surplus of single men. Such a surplus would not make women sexually irresponsible, since women are naturally inclined to form stable, long-lasting relationships.
This view was notably advanced by Pedersen (1991). He predicted that the recent shift to a higher sex ratio among singles would mean less divorce, less illegitimacy, less marital instability, higher birth rates, and greater commitment by men to getting an education and pursuing a career. These presumed benefits caused many, particularly on the political right, to see the new marriage market as a godsend. As recently as 2004 the Wall Street Journal ran an opinion piece that praised the wife shortage and its beneficial influence on the American family (Wilson, 2004).
There is another reason for the complacency of the commentariat. Singleness is a topic where older women do most of the talking and writing. For them, the man shortage is what really matters.
That the adverse marriage market position of young men has been overlooked may be due to the traditional tendency in demography to examine mainly female marriage and partnership. One author pointed to the marriage market difficulties of older women as being the “real” marriage squeeze (Veevers 1988), but in doing so ignored the partner shortages experienced by young men — an issue of greater demographic significance since it occurs at and before the prime ages of male marriage. Davis and van den Oever (1982) suggest that the surplus of unmarried men at young ages is of little importance since most will ultimately marry. (Ni Bhrolchain & Sigle-Rushton, 2005, pp. 59)
From a broader societal viewpoint, we should worry more about the lack of wives for younger men under 35 than about the lack of husbands for older women over 45. The latter are no longer able to have children and are simply seeking companionship. In contrast, the former risk being denied not only companionship but also a role in reproduction.
