"For many people, regardless of sexual orientation, a wedding is no longer the first step into adulthood that it once was, but, often, the last. It is a celebration of all that two people have already done, unlike a traditional wedding, which was a celebration of what a couple would do in the future.
Consistent with this shift in meaning, different-sex couples, like the many of the same-sex couples who have married recently, are starting their marriages later in their lives. According to the Census Bureau, the median age at first marriage—the age at which half of all marriages occur—was 27.4 for women and 29.5 for men in 2017. That’s higher than at any time since the Census began keeping records in 1890."
