Sweden and West Germany have had persistently high divorce rates in recent decades, but these two welfare states were differently equipped to mitigate the economic consequences of divorce for individual security in old age: Sweden followed a gender-equal policy approach to enable women and men to achieve economic autonomy, while West Germany, following the male-breadwinner model, introduced the system of 'divorce-splitting' to account for differences in women's and men's income. Against this background, this study uses large-scale register data from the German Public Pension Fund and the Swedish population registers to examine how divorce is related to the monthly public old-age pension income of women and men. The main comparison groups are divorced and (re)married individuals who entered retirement between 2013 and 2018. We descriptively show annual income histories from ages 20 to 65, and calculate monthly public old-age pension income with respect to lifetime income and pension regulations, such as the supplements/deductions for 'divorce-splitting'. Multiple ordinary least square regression models further examine how family status relates to monthly public old-age pension income by gender. The results reveal that women and men in Sweden experience similar working histories, although women's incomes are lower. This is also reflected in women still having lower pension incomes than men. However, divorced and married women show comparable pension incomes, while divorced men receive approximately 26 per cent less pension income than married men. In West Germany, divorced women have significantly higher pension incomes than married women. The system of 'divorce-splitting' increases women's and decreases men's pension incomes, which seems to equalise their pension incomes. However, both stay below a married man's pension income. The findings indicate economic inequality in public old-age pension income by family status in Sweden and West Germany.
