    “Like two peas in a pod?” Homogamous personalities, education, and union dissolution

    by Elias Hofmann, Sandra Krapf

    This paper examines the association between the level of similarity in the “Big Five” personality traits of the partners in different-sex couples and their risk of union dissolution. Prior research has mainly focused on homogamy in socio-economic, demographic, and cultural characteristics, such as age, education, employment, and religion. The few studies on the effects of homogamy in the personalities of the partners on separation find mixed results. We extend on this by analysing the moderating effect of education. Using data from the German Socio-Economic Panel (SOEP) for the 2005–2019 period, we follow 3958 coresidential couples and observe 534 separations. Personality is measured via the “Big Five” personality traits. We estimate discrete-time event history models for union dissolution. In addition to reporting the main effects, we calculate interactions between personality and the level of education of the partners. Our results indicate that greater dissimilarity with regard to the personality trait “openness” is associated with a higher probability to separate. However, analysing interaction effects reveals that this is relevant mainly among medium educated men. Moreover, persons with high education seem to be less likely to separate if they are dissimilar from their partner in their level of “extraversion”. These findings suggest that relationship dynamics differ across educational groups.

    Education and Intended Number of Children in Germany, Moldova and Norway: An International Comparison Using FReDA and GGS-II-data

    by Sandra Krapf, Isabella Buber-Ennser, Martin Bujard

    In this study, we compare the intended number of children in Germany, Moldova and Norway in 2020 and 2021, during the COVID-19 pandemic. In a first step, we compare the intended number of children (including children born) in the newly available Generations and Gender Survey round 2 (GGS-II) and the German FReDA-GGS data. In a second step, we estimate the number of further intended children with multinomial logistic regression models. The results reveal considerable differences across the three countries. Respondents in Moldova plan to have rather large families (on average 3.3 children, including children born), whereas individuals in Norway and Germany intend to have 2.0 and 1.8 children, respectively. In the multinomial logistic regression analyses, we find differences in the association of educational level and fertility plans by gender and country. In Germany, education is positively related to the intention to have further children. This pattern is more pronounced for women than for men. Furthermore, this association is also found among Norwegian men. In Moldova, we find only weak evidence for this association. For Norwegian women, education and the intention to have further children also seem to be unrelated. While most data about the intended number of children refer to the 2000s or earlier, we contribute to the literature by providing recent insights on the intended number of children in three European countries, including Moldova, a country that is understudied in demographic research. * This article belongs to a special issue on “Family Research and Demographic Analysis – New Insights from the German Family Demography Panel Study (FReDA)”.

    Parental repartnering and child well-being: What role does coresidence play?

    by Jana Kuhlemann, Sandra Krapf

    Objective: The paper examines the effects of parental repartnering (including residential and nonresidential partnerships) on children’s well-being. Background: An increasing number of children experience the repartnering of their parents. While previous research has focused on coresidential repartnering, this paper also considers the transition to a steady nonresidential (living apart together – LAT) partnership of formerly single parents. Specifically, the paper examines whether these transitions differ in their effect on children. Method: This study uses data from the German Family Panel (pairfam) to analyze the effects of parental repartnering on children’s emotional and behavioral well-being. The children in the sample were seven to 16 years old. Individual fixed effects regressions were estimated for two types of parental partnership transitions: the formation of a LAT partnership and the formation of a coresidential partnership. Results: The results show that children's emotional symptoms increased in response to both parental LAT repartnering and coresidential repartnering, whereas children’s conduct problems increased only in response to parental coresidential repartnering. Conclusion: These findings suggest that the formation of a nonresidential partnership by a parent can affect children's emotional well-being, and thus should be considered when analyzing post-separation family development.


  • Housing density and its consequences for couples in Germany: staying, moving, or breaking up?

    by Maike Van Damme, Sandra Krapf, Michael Wagner

    High housing density has been considered a stressor that is detrimental to couples’ relationships. However, empirical research on this topic has been mixed, which might be due to the fact that not all couples respond to density in the same way. We contribute to the literature by not only considering separation as a potential reaction to density but also moving to a new place. Moreover, we combine insights from different theoretical models to explain how couples react differently to an overcrowded home, depending upon their resources. For our analyses, we use the German Family Panel PAIRFAM (10 waves, 2008/09 to 2017/18) with a sample of N = 4180 couples, of which 484 experience a move and 488 a separation. Applying competing risk models, we find that vulnerable groups such as the poor and the low-educated are significantly more likely than others to separate when in a dense home rather than to stay in the same dwelling.

    The Transition to a Coresidential Partnership: Who Moves and Who Has the Partner Move In?

    by Sandra Krapf, Clara H. Mulder, Michael Wagner

    Moving into a joint household is an important step in the process of union formation. While a growing body of literature investigates differences between those couples who start coresidence and those who do not, we know little about the likelihood of moving upon the start of coresidence. The aim of this paper is to investigate how individual and couple-level characteristics are associated with moving, or having a partner move in, at the start of coresidence. We use data from 10 waves of the German Family Panel pairfam for those who started coresidence (n = 983) and estimate logistic regression models of moving versus having a partner move in. The respondents in the sample are quite young with a mean age of 27. For long-distance relationships, those with a higher level of education than their partner and women who were living in close proximity to their parents were less likely to move. In short-distance relationships, respondents living in the parental home or in crowded housing were more likely to move than those living in uncrowded housing. In contrast with previous research, we did not find that women were more likely to move than men. Our results highlight that factors like educational resources, housing demands, and local family ties have differential effects on moving decisions at the start of coresidence depending on the distance moved.

    Partnership Living Arrangements of Immigrants and Natives in Germany

    by Anne-Kristin Kuhnt, Sandra Krapf

    This paper compares the partnership arrangements of Turkish and Ethnic German immigrants (i.e., return migrants from Ethnic German communities from predominantly Eastern European countries), the two largest migrant groups in Germany, and native Germans. Most existing analyses of migrants' partnerships focus on intermarriage, marriage formation, or union dissolution. We know only a little, however, about the prevalence of non-marital living arrangements. Given that single person households and cohabitation are widespread phenomena mainly in post-materialist societies, analyzing whether immigrants engage in these behaviors sheds light on potential adaptation processes. The analyses are based on the German Microcensus of the years 2009 and 2013, with a focus on adults in the 18–40 age group. First, we present descriptive findings on the prevalence of partnership arrangements of immigrants and native Germans. Second, we estimate cross-sectional regressions with the partnership arrangement as the outcome variable in order to control for compositional differences between immigrant groups with respect to education. Our results show that while the vast majority of first-generation immigrants are married, the share of married natives is considerably smaller. Living in an independent household without a partner and cohabitation are rare phenomena among immigrants. By contrast, about one in seven natives is cohabiting and more than one quarter is living in an independent household without a partner. The most prevalent partnership living arrangement of the Turkish second generation is living in the parental household without a partner. These results are robust after controlling for education, age, and year in the multiple regression analysis.

    Housing Affordability, Housing Tenure Status and Household Density: Are Housing Characteristics Associated with Union Dissolution?

    by Sandra Krapf, Michael Wagner

    Housing is an important dimension of social inequality between couples, but it has been largely ignored in prior research on union dissolution. Extending the literature that controlled for the stabilizing effect of homeownership, we investigate whether housing, measured as household density, housing tenure and housing affordability, is related to the risk of union dissolution. Based on data from the German Family Panel (pairfam), we analyze 3441 coresidential partnerships. We run discrete-time event-history models to assess the risk of separation within a time frame of 7 years. Housing affordability is found to be negatively related to the risk of union dissolution among couples, as those couples with a high residual income (i.e., household income after deducting housing costs) were less likely to separate than those with a lower residual income. By contrast, household density is found to be unrelated to separation. In line with previous research, our findings indicate that homeowners had more stable relationships than tenants. The analysis shows that this was the case regardless of whether the home was jointly owned or was owned by one partner only.
