Recent US data shows that 55% of married couples in 2021 had the husband older by at least 1 year, yet many studies also report smaller average gaps over time. First-marriage data in the US puts the average age gap at 2.3 years, with college-educated couples averaging 1.8 years versus 2.6 years for non-college in 2021. The question is whether demographic shifts and education patterns are reshaping who marries across ages, and what happens when the difference stretches well beyond a typical gap.
