Bad news for Wedding Crashers' John and Jeremy: Marriage rates — and thus big, bumping weddings — have plummeted to a historic low in the last two years. In 2011, a mere 51 percent of Americans were married, in comparison to 1960's statistic of 72 percent.

On Monday, a private research company called Demographic Intelligence released a study speculating that the marriage rate will "remain at 6.8 marriages per 1,000 people in 2013, where it's been since 2009 (compared to 7.3 in 2007)," according to The Huffington Post. One that that will definitely be increasing? Weddings. The research predicted that there will be a significant spike in the next two years, hitting 2.208 million in 2015, up from 2.168 million this year. And just as more-and-more women are "Leaning In," the average age at first marriage will also increase by 2015 — 27.1 for women and 29.2 for men.

There's no scientific rhyme or reason for the decrease in tying the knot, but experts implicate divorce, gradual economic recovery, and rising college debt as three of the primary reasons. Check back with us in 2015, and in the meantime, monitor your invites during this year's wedding season!
