When Do American Women Marry? Age Statistics

A half-century of rising marriage age

The Census Bureau has estimated median age at first marriage since 1890, making it one of the longest demographic series in existence. The female median hovered between 20 and 22 from 1890 through 1970, bottoming out at 20.1 in 1956 during the postwar marriage boom. It then began a continuous climb: 22.0 by 1980, 23.9 by 1990, 25.1 by 2000, 26.1 by 2010, and roughly 28.5 today.

The male median has followed a parallel track about two years higher, currently near 30.5. Notably, the age gap between spouses has compressed over time, from around four years in the early twentieth century to roughly two years now.

Never-married shares by age and race

The marriage delay translates directly into never-married shares at each age. Nationally, 85% of women aged 18-24, 45% of women aged 25-34, and 20% of women aged 35-44 have never married. The 25-34 decade is the hinge: a woman entering it has an 85% chance of never having married, while a woman leaving it more likely than not has.

Race differences are substantial. Hispanic women marry earliest, with only 38% never married at 25-34. Asian women marry latest but most completely, going from 92% never married at 18-24 to 20% by 35-44. Black women both marry latest and least: 68% have never married at 25-34 and 45% at 35-44, more than double the rate of any other group in that bracket.

Education stratifies marriage timing within every group. College-educated women cluster their first marriages tightly in the late twenties and early thirties, while women without degrees marry across a much wider age spread, with more marriages both before 25 and never at all. Demographers call this the diverging destinies pattern: later but more stable marriage among the educated, and less marriage overall among the less educated.

Divorce enters the picture in the thirties

First marriages concentrated in the late twenties mean divorce becomes demographically visible about a decade later. Census data shows just 2% of women aged 18-24 are divorced or separated, rising to 12% at ages 25-34 and 22% at ages 35-44. In the oldest bracket, divorced and separated women actually outnumber never-married women.

Divorce risk is not evenly distributed. Marriages beginning after age 25, between college graduates, tend to last far longer; demographic analyses of federal survey data consistently show college-educated women who marry in their late twenties face lifetime divorce probabilities well below the often-quoted 40-50% figure, which is dominated by early marriages.

Why marriage keeps moving later

Three forces explain most of the delay. First, education: 47% of women aged 25-34 now hold a bachelor's degree or higher, and degree completion plus early career-building pushes marriage past the mid-twenties almost mechanically. Second, cohabitation has replaced early marriage as the first coresidential union for a majority of couples; Pew reports most adults now live with a partner before marrying, adding years to the path to the altar.

Third, attitudes have shifted. The General Social Survey shows a steady decline in the share of Americans who view marriage as a prerequisite for a full life, and Pew finds financial stability increasingly cited as something to achieve before marriage rather than through it. Demographers describe the result as marriage becoming a capstone rather than a cornerstone of adult life.

Run the numbers yourself

Marriage timing determines how many women at each age have never been married, which is a core filter in the Female Partner Calculator. You can combine never-married status with age range, education, and other criteria to estimate the share of US women matching your full profile.
