The average age for Americans getting married has reached a historic high — 27 for women and 29 for men — a jump from the 1990 average marrying age of 23 for women and 26 for men.

While delaying marriage has advantages — a lower divorce rate, higher income for women and fewer and less intense arguments between spouses — studies show there also may be benefits to tying the knot before age 30. (However, there is such a thing as marrying too young. Research shows that marriages beginning when a woman is 18are twice as likely to end in divorce as those beginning when she is 22.)

Below are five reasons to get married in your 20s.

1. It could make you happier.

According to the National Marriage Project’s 2013 “Knot Yet” report, the highest percentage of people ages 20 to 28 who consider themselves “highly satisfied” with their lives are married, as opposed to single or cohabiting. What’s more, the largest number of women who described their marriage as “very happy” tied the knot when they were 24 to 26. A 2010 study found that “the greatest indicated likelihood of being in an intact marriage of the highest quality is among those who married at ages 22–25.”

2. You’ll make more money (at least if you’re a man).

An analysis of American Community Survey data from 2008 to 2010 revealed that among men in their mid-30s, those who married in their 20s had the highest levels of personal income. Economists have found, in general, that married men earn more than single men — even when you control for other factors like age and education.

3. You’ll have more sex.

Couples who marry in their 20s tend to have more frequent sex than those who marry later. In a 2011 paper, Dana Rotz of Harvard University wrote that “a four year increase in age at marriage is associated with a couple having sex about one time less per month.” What’s more, married people as a whole have more sex than their single counterparts. The sooner you marry, the more time you’ll be spending between the sheets.

4. You’ll drink less alcohol.

A 2012 study published in the Journal of Health and Social Behavior found that married and engaged young adults reported lower frequency of drunkenness than those who are not in a serious romantic relationship. “Marriage and engagement likely carry with them a heightened sense of responsibility and obligation and a less active social calendar, which leads to less drunkenness,” the study’s authors wrote. Laying off alcohol has many health benefits, including weight loss, better sleep, better skin and a reduced risk of some cancers.

5. There’s nothing to be gained from waiting — if you think you’re ready.

We certainly aren’t advocating a rush to the altar, but if you feel like you’re prepared for that next step, go for it. Research says there’s no advantage to delaying marriage just for the sake of delaying it. A 2010 study by sociologists Norval Glenn and Jeremy Uecker states that “A 25-year-old person who meets an excellent marriage prospect would be ill-advised to pass up that opportunity only because he/she feels not yet at the ideal age for marriage. Furthermore, delaying marriage beyond the mid-twenties will lead to the loss during a portion of young adulthood of any emotional and health beneﬁts that a good marriage would bring.”
