Why Divorce among older adults has tripled since 1990

America’s oldest married couples are ending long marriages at a pace that has startled even family researchers.

Story Snapshot

The divorce rate for Americans 65 and older has roughly tripled since 1990.
Researchers also found that the share of older adults who are divorced has climbed sharply.
The rise is part of a wider gray divorce trend, while younger-adult divorce has fallen.
The biggest debate is not whether the trend exists, but how to measure it and explain it.

The Numbers Behind the Shock

The headline is real, and it is strong. Bowling Green State University’s National Center for Family and Marriage Research says the share of adults 65 and older who were divorced rose from 5.2 percent in 1990 to 15.2 percent in 2022. Pew Research Center also reported that, among married adults 65 and older, the divorce rate roughly tripled from 1990 to 2015. Those are different measures, but they point in the same direction.

The older-adult pattern stands out because younger adults moved the other way. The same research line shows divorce falling for people in their twenties and thirties while rising among older adults. A Bowling Green data brief found the sharpest jump among people 65 and older, where the divorce rate tripled from 1.8 to 5.5 divorces per 1,000 married persons between 1990 and 2021. That is why researchers call it gray divorce.

Why Researchers Think It Is Happening

Researchers do not point to one single cause. The Census Bureau says divorce among adults 50 and older has risen since the 1990s, often linked to the marital instability of the aging baby boomer generation. Other widely cited explanations include longer life expectancy, more financial independence for women, and changing ideas about what a good marriage should feel like. These are plausible drivers, but the sources mostly describe them rather than prove each one on its own.

That matters because late-life divorce is not just a personal choice story. It also reflects how a generation has aged. People who married in earlier eras now live longer, expect more from marriage, and are less willing to stay in a quiet dead zone. Some researchers describe that as the end of an “empty shell” marriage. The evidence here supports the trend. It does not let anyone reduce the trend to one neat cause.

Why the Public Conversation Gets Messy

The biggest source of confusion is measurement. Some reports use the divorce rate per 1,000 married people. Others use the share of adults who are divorced. Still others use the share of all divorces that involve older adults. Those numbers are related, but they are not the same thing. A headline can sound explosive while the underlying table is describing a narrower change in one age band.

That is also why the phrase “elderly divorce” can blur the picture. Researchers more often use “gray divorce” for people 50 and older, then separate out the 65-plus group for deeper analysis. That distinction matters. Much of the growth sits in the 50-plus world, but the fastest rise inside that group has been among the oldest married adults. In plain English, the change is real, but the age brackets matter.

What This Means for Families

Late-life divorce can hit harder than many younger couples expect. It can affect retirement income, housing, inheritance plans, and adult children who thought the family story was already settled. That is one reason the topic keeps showing up in legal, psychological, and retirement-planning coverage. The divorce itself may look private. The fallout is often shared by an entire family system that assumed the marriage was permanent.

The strongest reading of the evidence is simple. Older-adult divorce in the United States has risen sharply, especially since 1990, and the increase is concentrated in the 50-plus and 65-plus groups. The weaker point is not the trend. It is the public habit of mixing metrics and stretching the story beyond what the data can cleanly prove. On this topic, the numbers are dramatic enough without decoration.
