By the ten-year mark, a first marriage in the United States has roughly a 33% chance of having ended in divorce. A second marriage crosses that same ten-year line at 39%, according to the federal government’s own long-running data on marital dissolution. That six-point gap holds even earlier: within the first five years, 20% of first marriages have dissolved compared with 23% of remarriages. The popular story about second marriages is that people finally get it right, older, wiser, done with the mistakes of their twenties. The numbers tell a plainer story: the do-over marriage is, on average, somewhat more fragile than the one that came before it, not less.
That data comes from the National Center for Health Statistics, the federal agency inside the CDC that tracks marriage and divorce for the country, in a report titled “First Marriage Dissolution, Divorce, and Remarriage” based on the National Survey of Family Growth. It remains the government’s most detailed breakdown of how marriage order affects the odds of divorce, and researchers at the National Center for Family and Marriage Research at Bowling Green State University have kept tracking the remarriage side of the picture ever since.
The Wiser-The-Second-Time Myth
The idea that people bring more self-awareness into a second marriage isn’t wrong, exactly. Many do arrive with a clearer sense of their own patterns and less patience for red flags they ignored the first time. What that self-awareness runs into is a set of structural pressures a first marriage rarely has to deal with at all: blended finances from two separate financial histories, custody schedules and coparenting relationships with an ex, stepchildren who did not choose this new family and may actively resist it, and often less social support, because friend groups and even extended family sometimes stay loyal to the first spouse. None of that shows up as a variable in a wedding toast. All of it shows up in the divorce data.
Age matters too, and not in the direction people usually assume. The NCHS data shows women who remarry before age 25 have a 47% chance of that marriage dissolving within ten years, compared with 34% for women who remarry at 25 or older. Marrying young the second time carries almost as much risk as marrying young the first time, which cuts against the idea that simply having been married before is protective on its own.

Remarriage Is Also Getting Rarer
There’s a second trend worth putting next to the divorce numbers: fewer people are remarrying at all. The remarriage rate for men fell from 48.9 per 1,000 previously married men in 2008 to 34.4 in 2023, and for women from 25.2 to 18.5 over the same period, per Bowling Green’s most recent family profile. Meanwhile, the rate of first divorces has also dropped substantially, from 16.9 per 1,000 married men in 2008 to 11.5 in 2023, according to a separate BGSU profile. Marriages of all kinds are ending less often than they did fifteen years ago, and people are also less inclined to remarry after they do end. Put together, that suggests some of what looks like “second marriages fail more” reflects a shrinking, more cautious pool of people even attempting a second marriage in the first place, not just something inherently unstable about remarriage as an institution.
That nuance doesn’t erase the core finding. Even against a backdrop of fewer, more careful remarriages, the dissolution rate for second marriages still runs ahead of first marriages at every measured interval in the federal data. Whatever wisdom people bring the second time around, it hasn’t been enough to close that gap.
What Actually Helps
Family researchers who study remarriage consistently point to the same few practical differences between second marriages that hold and ones that don’t: clear, agreed-upon boundaries with stepchildren before the wedding rather than after conflict starts, financial transparency from the beginning instead of merging accounts by default, and realistic expectations about how long it takes a blended family to feel like one family, often years rather than months. None of that is romantic advice. It’s closer to project management. But the couples who treat a second marriage as a genuinely different structure, rather than a first marriage with better judgment, appear to be the ones most likely to beat the odds the data lays out.
The lesson isn’t that second marriages are a bad bet. Most of them, by definition, are marriages between people who already know what a serious relationship costs and chose to try again anyway. The lesson is that surviving a first marriage’s ending doesn’t automatically inoculate anyone against the specific, added pressures a second one carries. Wisdom helps. It just isn’t the whole equation.
