Divorce among high and low divorce-prone populations following unilateral divorce laws
Objective: This study analyzes heterogeneity in divorce rates after the 1987 transition from mutual consent to unilateral no-fault divorce in Finland.
Background: Marriage and divorce legislation can impact divorce rates. Some groups may be more responsive to changes in legal context than others. We propose that unilateral no-fault divorce laws either (a) increase divorce more in high or low-divorce-prone groups, or (b) increase divorce equally across these groups.
Methods: We use population-wide register individual-level data from Finland to identify salient social groups with different divorce propensity, including ethno-linguistic and religious affiliations with divergent divorce propensity, and couples of different parental status, marriage length, marital history. We use piece-wise constant exponential survival models to estimate the association with divorce proneness before and after the introduction of mutual consent divorce laws.
Results: Divorce rates increase in all studied subgroups by about 60 percent in the years following unilateral divorce. We found no support for the hypotheses that high or low divorce-prone groups are particularly responsive to divorce liberalization.
Conclusions: The findings speak towards a universal rather than heterogeneous effect of divorce law liberalization.
