What You Need to Know for Sure Before Moving in Together
People widely believe cohabitation is a good test run but there's a big hitch.
Posted July 24, 2016
A “Majority of Americans Now Believe in Cohabitation.” That’s the headline and conclusion from a national survey conducted by the Barna Group.1 They surveyed 1,097 adults in April 2016, finding that 65 percent of Americans now approve of cohabiting prior to tying the knot, while 35 percent do not.2 Given that nearly 70 percent of Americans marrying today will cohabit before they wed,3 these findings are not surprising.
The Barna Group also found that 84 percent of those who support premarital cohabitation do so because it provides a test of compatibility prior to marrying. That's the main focus of this piece, but first, here are some other findings from the report:
- Millennials are more likely (72 percent) to endorse cohabitation prior to marriage than the older generation (36 percent).
- Those identifying as liberal (86 percent) are more likely to endorse cohabitation prior to marriage than those identifying as conservative (37 percent).
- Those identifying as more religious, particularly those who report being practicing Christians, are the least likely (41 percent) to endorse cohabiting before marriage while those reporting no faith at all are the most likely to embrace the practice (88 percent).
The survey also asked about behavior, finding that 57 percent of those surveyed had cohabited with a partner outside of marriage at some point. Further, and entirely consistent with what we might expect, older, more conservative, and more traditionally religious respondents were the least likely to report a history of cohabiting.
The embrace of cohabitation before marriage is widespread. As Roxanne Stone, editor-in-chief for the Barna Group, explained, “Even a growing number of parents—nearly half of Gen-Xers and baby boomers, and more than half of millennials—want and expect their children to live with a significant other before getting married.”
Cohabitation is here in a big way.
Reasons Why People Believe Cohabitation is Good
The Barna Group found that 84 percent of those who approve of cohabiting before marriage said that it was valuable for testing compatibility. This has been the dominant belief of young adults for 20 years or more. By way of comparison, in a detailed report on attitudes related to family in 2001, sociologists Arland Thornton and Linda Young-DeMarco4 (citing findings from the Monitoring the Future project at the University of Michigan) noted that, by the late 1990s, more than three-fifths of high school students in the U.S. endorsed the sentiment, “It is usually a good idea for a couple to live together before getting married in order to find out whether they really get along.’’
The Barna Group found that other reasons for valuing premarital cohabitation paled in comparison to testing, with the reason that “it’s convenient/practical” coming in at 9 percent and “cheap rent” coming in at 5 percent.
Reasons Cohabiters Give for (Actually) Moving In Together
From 2007 to 2012, we followed a national sample of 1,294 unmarried young adults (ages 18 to 34) who were in serious romantic relationships, surveying them about their personal lives and relationships for 11 waves.5 This is the Relationship Development Study (RDS), and the sample well represents Americans in that age range.
At the first time point in this longitudinal study, we asked people if they were cohabiting, and if so, their reasons for doing so. Based on prior work in this area,6 we gave people six options for ranking reasons for moving in with their partners7 (see the chart below). Although the Barna Group showed that most people who endorse cohabiting before marriage believe it's a good idea because it provides a good test of compatibility, that’s not the most common reason people give for actually moving in together.
As you can see, we found that the Number One reason both males and females gave for moving in together was to spend more time with their partner. Convenience was the second most strongly-endorsed reason, followed by wanting to take a step up in commitment.8Convenience would include the types of financial benefits noted in the Barna Group report. In our sample, men and women strongly diverged in two categories: Women were more likely than men to say they cohabited because they had a child to raise (13 percent vs. 6.6 percent) while men were more likely than women to say they cohabited to test the relationship (10 percent vs. 4.5 percent).
Is Cohabiting a Good Test of a Relationship?
Around 2005, we (particularly Galena) began carefully studying the reasons people cohabit as part of a range of efforts to study cohabitation and why it was typically not associated with the improved outcomes in marriage that most people expect. Using an earlier sample of cohabiters (not the national and more representative sample we have in the RDS), we gathered in-depth quantitative data from 120 couples, and looked at the reasons people gave for cohabiting and what those reasons were associated with.9
In that data set, the top three reasons people gave for cohabiting were more time together (61 percent), financial convenience (19 percent), and to test the relationship (14 percent). These findings parallel those we obtained in the same sample of that report using a more sophisticated scale of reasons for cohabitation, which was used in more complex analyses of the various reasons people have for cohabiting.
Women who report cohabiting for reasons of convenience were more likely to report a lower level of confidence in their relationships, less commitment, and higher levels of negative dynamics with their partners. Those findings are consistent with the fact that, for some, cohabitation is driven by perceived (and real) necessities. Some people really do have poorer options, and they are more likely to end up in difficult relationships in which cohabitation would not otherwise have been their first choice—at least with “this” partner.
What about testing? As with our national data set, men were more likely than their partners (all women in this sample) to report cohabiting in order to test the relationship. We examined the personal and relationship characteristics of both men and women who reported testing, and found that:
- “For men, higher levels of depressive symptoms, generalized anxiety symptoms, difficulty depending on others, and anxiety about abandonment were significantly associated with higher scores on testing.” (p. 247)
- “For women...greater abandonment anxiety was significantly associated with higher testing scores.” (p. 247)
- “For both men and women, greater negative interaction and psychological aggression, and lower relationship confidence and adjustment were significantly associated with higher scores on the testing subscale. For men only, greater physical aggression and lower levels of dedication were significantly associated with testing the relationship.”
These findings suggest that cohabiting to test a relationship is associated with many kinds of negatives. Does that mean that cohabitation causes those negatives? Probably not. There is a lot more evidence that those negatives were there before cohabiting.
If you are considering whether or not you should move in with someone to test your relationship, it’s probably not a wise thing to do. It seems to us that many people who think about testing their relationship by cohabiting already know, on some level, what the grade of that test may be; they are just hoping that the answer looks better over time.
Even cohabiting to spend more time together may not be without risk. We’ve argued elsewhere and often—with a lot of empirical evidence in many published studies—that the Number One thing people ignore about the risk of cohabiting is that it makes it harder to break up. Cohabiting relationships break up all the time, and increasingly so,10 but the relative difference is the point: All other things being the same, a couple that is cohabiting will have a harder time breaking up than a couple that is only dating. We think that’s a big deal. (Read more about what we call “the inertia of cohabitation" here and here and here. Or, see our four-minute video on the subject: Relationship DUI.)
Because many people cohabit before even having mutual clarity about commitment, such as engagement or marriage, some people end up staying in relationships, including on into marriage, that they otherwise would have left behind.11 Essentially, many people slide into situations that make it harder to end a relationship before they have made a clear decision about what is best. The situation looks quite a bit different for those who have strongly clarified mutual commitment to the future before moving in together, such as by being engaged or even—gasp—being married.
Cohabitation Fails the Test
There are better ways to test a relationship than to do something that makes it harder to break up before you’ve really figured it all out. Take a relationship education course (i.e., some kind of premarital preparation before you get engaged), talk about what a future together would look like, and see if you are compatible by dating. Take the time to see your partner in a variety of different social settings.
Ever take any college classes? If so, you know that people sometimes sign up for a class, then decide part of the way through the semester that the class is not for them and drop it. But some people figure this out too late and cannot drop the class, or they drop it late and lose their money.
It’s easy to slide into cohabitation without first having a serious discussion or decision and then get stuck. When it comes to moving in together before marriage, some people may find that they are failing a class that has become too hard to drop.

1. The Barna Group specializes in survey work that is often used by those in religious ministry. As for the methods used by the Barna Group, they seem reasonable to us and the findings are entirely consistent with what we know in this field. However, we have not examined the specific procedures beyond what is stated in their report, where they note: “The study on which these findings are based was conducted via online survey from April 7 to April 14, 2016. A total of 1,097 interviews were conducted. The sample error is plus or minus 2.8 percentage points at 95-percent confidence level. The completion rate was 85%.”
2. In creating their report, the Barna Group combined those who either strongly or somewhat agree into one group and those who either somewhat or strongly disagree into the other.
