Most Americans Live Together Before Marriage. Here’s What to Talk About Before You Move In
A Pew Research Center analysis found that 77% of Americans in their late 30s and early 40s have lived with a partner they weren’t married to. Here’s what the data says about how those relationships turn out, and the conversations to have before you sign a lease.
Living together is now the norm, and often a step toward marriage. A Pew Research Center analysis of a federal survey, published in August 2026, found that 77% of U.S. adults ages 38 to 43 have lived with an unmarried partner, and two-thirds of them went on to marry someone they lived with. The typical cohabiting relationship lasted 18 months before ending in marriage or a breakup. Before you move in, talk about money, chores, space and what moving in means to each of you.
- 77% of U.S. adults ages 38 to 43 have lived with an unmarried partner, including 37% who have lived with two or more.
- Two-thirds (67%) of those who cohabited went on to marry a partner they lived with; most of them (70%) married the first one.
- The typical cohabiting relationship lasts 18 months before ending in marriage or a breakup.
- 26% have had at least one live-in relationship that lasted five years or longer.
- The talks that matter most before moving in: money, chores, space and what the move means to each of you.
It often starts with a toothbrush. Then a drawer. Then one of you does the math on two rents and says it out loud: “Should we just move in together?”
If you are asking that question, you are far from alone. New data shows that living together before marriage is the norm for most Americans, but what happens next varies a lot. Here is what the research found, and the conversations that make the move a good one.
What the new data shows
In August 2026, the Pew Research Center published an analysis of the National Longitudinal Survey of Youth 1997, a Bureau of Labor Statistics study that has followed the same Americans, born between 1980 and 1984, since they were 12 to 17 years old. In the latest round, conducted in 2023, they were 38 to 43.
77% of them had lived with an unmarried romantic partner at some point, including 37% who had lived with two or more different people. It was more common among adults without a college degree: 82% of those with a high school diploma or less had cohabited, compared with 70% of those with a bachelor’s degree.
Does living together lead to marriage?
Often, yes. Two-thirds (67%) of adults who had ever cohabited went on to marry someone they lived with. Most of them (70%) married the first partner they lived with, and another 22% married the second.
But it is not automatic: 28% of those who had ever cohabited had not married by their early 40s. Education made a big difference, too. Among adults who had cohabited, 77% of those with at least a bachelor’s degree married a partner they lived with, compared with 59% of those with a high school diploma or less.
These numbers describe patterns, not causes: they show who went on to marry, not that living together made it happen.

The typical cohabiting relationship lasted 18 months before ending in marriage or a breakup, according to Pew’s analysis. That number is a median, and it includes relationships that were still going at the time of the survey.
Some last much longer: 26% of adults who had ever cohabited had at least one live-in relationship that lasted five years or more, including 8% with one that lasted 10 years or longer.
In other words, moving in is often a turning point. For many couples, it is the moment the relationship either takes the next step or shows that you want different things. That is exactly why the conversation before the move matters so much.
“It’s common for adults in the United States to live with a romantic partner they’re not married to.”

The money talk before you sign a lease
Saving on rent is tempting, but it only works if you agree on the rules first. Money is already the top stressor for couples in a recent survey, and living together puts it on the table every single month. Settle these before the first payment:
- Rent and bills: 50/50, or in proportion to what each of you earns?
- The lease: if both names are on it, you may both be responsible for the full rent. Read it carefully and ask the landlord if anything is unclear.
- Shared costs: groceries, internet, streaming and furniture. Who pays, and how will you keep track?
- The “what if”: if you break up, who stays, who moves out and who keeps the couch you bought together?
This article is not legal or financial advice. For leases, shared purchases or property, consider talking to a lawyer or a financial professional.
Questions to ask before moving in together
Living together is not just a longer sleepover. A few honest questions now can save months of quiet resentment later:
- What does moving in mean to you? A step toward marriage, a trial run or a practical choice? With a typical live-in relationship lasting about 18 months before it becomes a marriage or ends, it is worth knowing you are on the same page.
- How clean is clean? Different standards for dishes and laundry can turn into daily friction.
- How much alone time do you need? One of you may recharge with friends, the other alone on the couch.
- Who visits, and how often? Friends, family and overnight guests.
- What are your deal-breakers? Pets, smoking, work hours, noise.
How to bring it up (and how to answer)
Whether you are asking or answering, the goal is the same: make it a conversation, not an ultimatum. And if you are not ready yet, say so kindly and clearly, with a reason.
Why it works: It shows excitement but treats the move as a shared decision, not a convenient default.
Why it works: It reassures your partner about the relationship while being honest about the timing.
Before you carry the first box
Moving in together can be a wonderful step. The couples who do it well are not the ones who never disagree; they are the ones who talk early, specifically and kindly about the boring stuff, like bills, chores and bedtimes.
Sharing a bed every night can be an adjustment, by the way. Plenty of couples sleep in separate rooms to get better rest, and it is not always a bad sign.
If a conversation gets tense, take a breath before you reply. We also have a guide for the moment your partner’s texts turn cold. And if your relationship is still new, you might enjoy why so many people pair up in the winter.

Frequently asked questions
How many couples live together before marriage?
In a Pew Research Center analysis of a federal survey, 77% of U.S. adults ages 38 to 43 had lived with an unmarried partner at some point, and two-thirds of them went on to marry someone they lived with.
How long do couples usually live together before getting married?
Pew found that the typical cohabiting relationship lasts 18 months before ending in marriage or a breakup. That is a median, and many live-in relationships last much longer.
When is the right time to move in together?
There is no perfect timeline. A better test is whether you have talked about money, chores, space and what the move means to each of you, and whether you both want it for more than saving on rent.
How should couples split rent when living together?
Common options are 50/50 or in proportion to income. What matters is that you agree before the first payment and revisit it if your incomes change. This is not financial advice.
What should we talk about before moving in together?
Rent and bills, chores, alone time, guests, deal-breakers and what moving in means to each of you: a step toward marriage, a trial run or a practical choice.
What happens if we break up after moving in?
Talk about it before you move: who stays, who leaves and how you split shared things. If both names are on a lease or you buy something big together, consider asking a lawyer about your options.
