Americans Used to Marry Young — So Why Did That Stop?

Americans used to marry in their very early twenties. Today, the median American man does not walk down the aisle until he is nearly thirty-one, and the median American woman waits until she is past twenty-eight. Nearly half of adults under thirty are still living with a parent, and the typical first-time homebuyer is now forty years old. In this deep dive, we unpack exactly how American marriage went from a near-universal milestone of early adulthood to something people now postpone for a decade or more, and in many cases skip entirely. We travel back to the 1950s and 1960s, when the median American man was marrying at twenty-two and a half and the median woman at just twenty, the youngest marriage ages ever recorded in modern U.S. history. We explain why that period was not the baseline of American life but a demographic anomaly, built on a very specific set of conditions: the GI Bill, mass suburbanization, Levittown-style tract housing, dominant union wages, limited birth control, and a rigid breadwinner-homemaker script. Then we trace the six dominoes that knocked that golden age down. The 1960 FDA approval of the birth control pill. The 1965 Supreme Court decision in Griswold v. Connecticut and its 1972 extension in Eisenstadt v. Baird. The collapse of middle-class manufacturing wages after the oil shocks of 1973 and 1979. The explosion of higher education and the student loan debt now carried by roughly 43 million Americans. The housing affordability crisis, with the median U.S. home price climbing to around $430,000 by 2025. The rise of cohabitation, and the quiet 1991 crossover when the median age of first birth fell below the median age of first marriage. We also cover the class divide that now defines American marriage, the regional patterns that make states like Utah and Arkansas look nothing like California or Massachusetts, and the international context, from South Korea's fertility collapse to Hungary's aggressive pro-natal policies.
