French Demographic & Spousal Earnings Study Findings:
- Couples where the female partner generates ~75% of income face a ~30% higher relative hazard of marital dissolution compared to 50/50 dual-earning couples.
- Sociological drivers: Role non-conformity stress, marital satisfaction differentials, and residual asymmetry in domestic second-shift labor burdens.
- In contrast, male breadwinner shares (e.g. 75% male / 25% female) exhibit dissolution rates closely aligned with the 50/50 baseline in Western demographic panels.
