Divorce hits housing differently for men and women in couples

When a marriage ends, the house where a couple built their life together becomes one of the most consequential battlegrounds of the divorce. A new study drawing on Finland’s world-class population registers reveals that the fallout is strikingly unequal, and that the gender composition of the couple matters in ways researchers have never before been able to measure. Women who divorce men suffer far greater losses in homeownership and are far more likely to be forced out of the marital home than their husbands, while women who divorce women experience smaller, more evenly matched losses. Yet the study also uncovers a sobering caveat: women in same-sex couples tend to start with less housing wealth to lose in the first place, and no divorced group fully recovers within three years.

The research, published in the open-access journal Genus by demographers Elina Einiö and Maria Ponkilainen of the University of Helsinki and the Max Planck Institute for Demographic Research, is the first to track the trajectories of homeownership surrounding divorce separately for women married to men and women married to women. By exploiting Finland’s unique combination of full-population register data and early legal recognition of same-sex partnerships, the authors were able to disentangle the gendered dynamics of divorce in a way that traditional studies of heterosexual couples cannot.

The theoretical starting point is the sociological concept of “doing gender.” Decades of scholarship, beginning with the influential work of West and Zimmerman, hold that gender is not simply a fixed attribute but something people enact in daily interactions, particularly within heterosexual relationships. Even when both spouses are employed, wives typically shoulder the bulk of housework and childcare, an arrangement that reflects convention rather than rational allocation of labor. According to this framework, women are on average more dependent on their partners and therefore at higher risk of losses in housing quality and security when divorce strikes. Same-sex couples offer a natural test of this idea: because both partners share a gender, they can more freely “undo” gender, dividing paid and unpaid work according to strengths and interests rather than normative expectations. If gendered expectations drive post-divorce housing losses, then women divorcing women should lose less, and lose more symmetrically, than women divorcing men.

To test this, the researchers constructed a dataset from Statistics Finland covering all couples who legalized a marriage or registered partnership between March 2002, when Finland first allowed same-sex registered partnerships, and December 2015. The final analytical sample comprised 290,018 couples: 500 female couples who divorced, 54,965 different-sex couples who divorced, and more than 234,000 couples who remained in intact unions. The study followed each individual for three years before and three years after the year of divorce, using register-based information on the tenure status of dwellings and on household residential codes. Homeownership was defined as living in an owner-occupied dwelling, either owning the house outright or owning the shares of an apartment, while retention of the marital home was defined as remaining at the last address the spouses had shared.

Statistically, the team employed repeated-measures logistic regression using generalized estimating equations with an unstructured correlation matrix, a technique that accounts for the repeated observations nested within each individual over time. Crucially, the models controlled for age, calendar year, and area of residence, the latter being important because same-sex couples are more likely to live in urban areas where house prices are higher. The results were expressed as predicted probabilities evaluated at the mean values of the other covariates, allowing direct comparison of housing trajectories across the four marital dyads: husbands and wives in different-sex couples, and older and younger wives in female same-sex couples.

The headline findings are stark. Three years before divorce, roughly 70 percent of divorcing women in different-sex marriages lived in owner-occupied housing, compared with about 60 percent of divorcing women in same-sex couples. As divorce approached, the trajectories diverged dramatically. Women divorcing men saw their probability of homeownership plummet from 72 percent to 53 percent in the year preceding the divorce, while their husbands’ probability fell more gently, from 72 to 62 percent. Women in same-sex couples experienced smaller declines, from around 60 to 50 percent. In the divorce year itself, when housing loss bottoms out, the probability of living in owner-occupied housing converged to roughly 42 to 44 percent for all divorced women, regardless of whether their spouse had been a man or a woman, while newly divorced men retained a notably higher level of 54 percent.

The picture for the marital home was equally revealing. The vast majority of divorcing individuals eventually left the shared address, but men who divorced women were significantly more likely to stay put than either women divorcing men or women divorcing women, even after accounting for age, year, and urbanicity. This aligns with bargaining theories of separation developed by demographers such as Clara Mulder and Michael Wagner, who argue that the spouse with greater relative resources is less likely to move out, and that custody of children further anchors the stayer. It also reflects, the authors suggest, the mechanics of Finland’s matrimonial property regime. Like other Nordic systems, Finland applies a deferred community of property: assets are owned separately during the marriage but divided equally upon dissolution, regardless of when they were acquired. Selling the marital home is often the simplest way to effect that equal division, and the loss of economies of scale after separation means neither spouse may be able to buy out the other.

Perhaps the most provocative result concerns income. When the researchers stratified the dyads by who earned more in the year before divorce, a consistent pattern emerged across all couple types: the higher-earning spouse suffered smaller losses in homeownership and was more likely to keep the marital home. Among women in different-sex marriages, those who outearned their husbands fared better than their lower-earning peers, though the gap was smaller than the advantage enjoyed by male breadwinners. Among women in same-sex couples, the wife who earned more was clearly better positioned to retain owner-occupied housing. In Finland, the legal obligation of one spouse to support the other generally terminates at divorce, meaning the pre-divorce housing standard must be maintained independently, making relative earnings decisive.

For the authors, these findings support the idea that nontraditional gender roles may protect women from the worst housing consequences of divorce. Women in same-sex couples divide paid and unpaid labor more equally, and their nearly identical housing losses, whether they are the older or younger spouse, suggest that “undoing” gender within the relationship translates into more symmetrical outcomes at its end. Conversely, women married to men appear to have “done” gender more traditionally, and 68.5 percent of them earned less than their husbands in the year before divorce, leaving them exposed when the marriage dissolved. Gender wage gaps and the lower pay typical of female-dominated occupations compound the problem.

Yet the study tempers any romantic reading of same-sex divorce. Women in female couples were substantially less likely to own their homes even while their unions were intact: 75 percent among non-divorcing women in same-sex unions versus 80 percent among their peers in different-sex marriages, and only about 60 percent among divorcing same-sex couples three years before separation. Female couples earn less overall, albeit more equally, than different-sex couples, which may have prevented them from buying property in the first place. The authors also note the possibility, considered less likely in the Nordic context than in North America, of discrimination against same-sex couples in mortgage markets, and point to evidence that women in Finland attach less importance to homeownership than men. Whatever the cause, the implication is uncomfortable: the smaller losses observed among divorcing women in same-sex couples partly reflect that they had fewer material resources at stake from the outset.

Another nuance concerns recovery. Although women in different-sex couples showed a modest rebound in homeownership during the three years after divorce, supplementary analyses revealed that this increase disappeared once individuals who newly cohabited were excluded. It remains unclear whether women who find new partners were already on an improving housing path or whether the new partner confers housing advantages. What is unambiguous is that no divorced group, men or women, in same-sex or different-sex couples, returned to its pre-divorce baseline within three years. Previous research indicates that the scars can last a lifetime: people who have experienced divorce are less likely to be homeowners even in later life.

The study’s methodological strengths are considerable. Because the data derive from administrative registers rather than surveys, they capture entire populations with negligible attrition, and the inclusion of continuously married comparison groups, observed around randomly assigned years, allows divorcing couples to serve as their own implicit benchmarks. Still, the authors are careful about limitations. Register data cannot reveal who initiated the divorce, whether couples had prenuptial agreements, what housing preferences motivated moves, or how children shaped post-divorce living arrangements. With childbearing among female couples rising across the Nordic countries, the effects of children on housing after divorce represent an urgent next question. The findings are also specific to Finland’s legal, economic, and social context and cannot simply be generalized to countries with different property regimes or weaker safety nets.

The broader significance of the work lies in what same-sex couples reveal about gender itself. By showing that housing losses are more equal between two women than between a husband and wife, and that relative income trumps gender in determining who keeps the home, the study suggests that the disadvantages divorcing women face are not biologically inevitable but socially produced, woven into the division of labor and earnings within heterosexual marriages. At the same time, the lower baseline of homeownership among female couples warns that equality within a relationship cannot compensate for scarcity between them. Divorce, the study makes clear, is a couple-level shock that wounds both partners, but it wounds them unequally, and the architecture of gender, as much as the law of property, shapes where the blows land.
