These gaps may result in what could be seen as desperate measures, Birger wrote.
For every two men that graduate (college), there are three women.Fewer peer men are keeping up and women are not looking at (those males) as potential mates."To be sure, the disparity exists in other faiths and leaders are making efforts to facilitate introductions and keep young adults involved and eligible to marry like-minded believers within the faith.Faith marriage crisis Beyond the numbers, there are cultural factors at play within religious communities, such as the LDS and Orthodox Jewish cultures which emphasize marrying within the faith. It's not you, it's a shortage of suitable males, one expert says.Dismissing common explanations such as a "hookup culture" in big cities and some college environments, business writer Jon Birger says in a new book, "Date-onomics," it's a numbers game.
If there are more available women than men, then the males will have the upper hand in dating, with some avoiding commitment while they look for a "better" prospect.
Nationally, he said, college campuses are 57 percent female to 43 percent male.
Birger tested his theory in religious communities where marrying within the faith is emphasized, such as Orthodox Judaism and The Church of Jesus Christ of Latter-day Saints. "I wanted to show that God-fearing folks steeped in old-fashioned values are just as susceptible to the effects of shifting sex ratios" as the non-religious were, he wrote.
Using data from a 2011 Trinity College analysis of Mormon population in the United States, Birger wrote, "There are now 150 Mormon women for every 100 Mormon men in the state of Utah — a 50 percent oversupply of women." Because there's so much choice for men, he adds, they hold out for the "perfect" mate, while women age out of the pool of eligible singles.
Orthodox Judaism comprises approximately 10 percent of America's 5.3 million Jews, according to data released this week by the Pew Research Center.
Birger cited research showing "for every 100 22-year-old men in the Orthodox dating pool, there are 112 19-year-old women — 12 percent more women than men," again leading to an excess of females in a community where the males typically wed younger women.
