This article describes trends in parental wealth homogamy among union cohorts formed between 1987 and 2013 in Denmark. Using high-quality register data on the wealth of parents during the year of partnering, we show that the correlation between partners’ levels of parental wealth is considerably lower compared with estimates from research on other countries. Nonetheless, parental wealth homogamy is high at the very top of the parental wealth distribution, and individuals from wealthy families are relatively unlikely to partner with individuals from families with low wealth. Parental wealth correlations among partners are higher when only parental assets rather than net wealth are examined, implying that the former might be a better measure for studying many social stratification processes. Most specifications indicate that homogamy increased in the 2000s relative to the 1990s, but trends can vary depending on methodological choices. The increasing levels of parental wealth homogamy raise concerns that over time, partnering behavior has become more consequential for wealth inequality between couples.

父母的财富：基于父母财富的组合交配随时间的趋势。

本文描述了 1987 年至 2013 年在丹麦形成的工会群体中父母财富同婚的趋势。使用关于伴侣当年父母财富的高质量登记数据，我们表明，与其他国家的研究估计相比，伴侣父母财富水平之间的相关性要低得多。尽管如此，父母财富同婚在父母财富分布的最顶端很高，来自富裕家庭的个人相对不太可能与来自低财富家庭的个人合作。当仅检查父母资产而不是净财富时，伴侣之间的父母财富相关性更高，这意味着前者可能是研究许多社会分层过程的更好衡量标准。大多数规范表明，与 1990 年代相比，2000 年代同性婚姻有所增加，但趋势可能因方法选择而异。父母财富同婚的程度越来越高，这引起了人们的担忧，即随着时间的推移，伴侣行为对夫妻之间的财富不平等变得更加重要。
