Research has shown considerable municipal-level variation in divorce rates within countries. Given the large increase in cohabitation over the past decades, this study examines whether similar differences can also be observed in the union dissolution risks of cohabitants. By investigating whether six municipal-level factors important in understanding spatial variation in divorce are also associated with spatial variation in the dissolution of cohabiting unions (financial uncertainty, gender roles, religiosity, social ties, alternative opportunities and educational attainment), this article aims to improve our understanding of municipal differences in the dissolution of cohabiting unions. This study is conducted on register data from Statistics Netherlands (2017–2018). For this study, unique union dissolution information per union type (marriage and cohabitation) is constructed for 355 Dutch municipalities. Nearly all explanatory factors are defined using publicly available municipal-level information. We use spatial lag regression models to analyse differences in municipal union dissolution risks for different union types. We find that municipal-level union dissolution risks of cohabiting and married couples are only moderately correlated, suggesting that the risk of union dissolution for cohabiting couples is not necessary high in municipalities with high divorce rates. Municipal-level indicators of social ties, religiosity and alternative opportunities are linked to municipal-level variation in union dissolution risks of married and cohabiting couples, whereas municipal-level variation in financial uncertainty and educational attainment are only linked to municipal-level variation in union dissolution risks of married couples.

比较各城市的婚姻和同居解除风险：哪些特征很重要？

研究表明，各国不同市镇的离婚率存在相当大的差异。鉴于过去几十年来同居现象大幅增加，本研究探讨了在同居者的婚姻解散风险中是否也可以观察到类似的差异。通过调查对理解离婚空间差异很重要的六个市级因素（财务不确定性、性别角色、宗教信仰、社会关系、替代机会和教育程度）是否也与同居婚姻解体的空间差异相关，本文旨在提高我们对解散同居婚姻的城市差异的了解。这项研究是根据荷兰统计局（2017-2018）的登记数据进行的。对于这项研究，为 355 个荷兰城市构建了每种工会类型（婚姻和同居）的独特工会解散信息。几乎所有解释因素都是使用公开的市级信息来定义的。我们使用空间滞后回归模型来分析不同工会类型的市政工会解散风险的差异。我们发现，同居夫妇和已婚夫妇的市级婚姻解散风险仅呈中度相关，这表明在离婚率较高的城市，同居夫妇的婚姻解散风险并不一定很高。市级社会关系、宗教信仰和替代机会指标与已婚和同居夫妇工会解散风险的市级差异相关，
