Abstract This study examines how married couples’ age differencesand gender dynamics influence retirement coordi outcomes of all marital couples in Sweden. Using , we find that the likelihood of couples retiring close in time decreases as their age difference increases but that age differences have a similar effect on retirement coordination for couples with larger age differences. Additionally, retirement coordination is largely gender-neutral in opposite-sex couples with age differences regardless of whether the male spouse is older. Additionally, male same-sex couples retire closer in time than both opposite-sex couples and female same-sex couples. The definition of retirement coordination as the number of years between retirements contributes to the literature on couples’ retirement behavior and allows us to study the degree of retirement coordination among all couples, including those with larger age differences.
