Who Initiates Divorce: Men or Women? 2026 Statistics & Top Causes

Divorce is a major life transition, but marriages rarely end because of a single argument, difficult period, or isolated event. Research suggests that divorce is often linked to a combination of factors, including declining commitment, infidelity, ongoing conflict, financial stress, substance misuse, violence, and changing expectations within marriage. 

According to reports, women initiate about 69% of heterosexual marital breakups, highlighting an important gender difference in how divorce begins. Older adults have also become a much larger share of the divorcing population, with nearly 40% of divorcing Americans now aged 50 or older. 

In this article, we take a closer look at who initiates divorce and the most commonly reported causes of divorce in 2026, including differences by gender, relationship type, age, and other key factors.

Key Who Initiates Divorce Statistics

• 69% of heterosexual marital breakups were wanted more by the wife, compared with 31% wanted more by the husband.
• 41% of female same-sex couples in one Finnish study divorced within 10 years, compared with 27% of male same-sex couples and 22% of different-sex couples.
• 75% of divorced participants identified lack of commitment as a major contributor to divorce.
• 59.6% reported infidelity or extramarital affairs as a major contributor.
• 57.7% identified excessive conflict and arguing as a major contributor.
• 45.1% said getting married too young contributed to their divorce.
• 26% of men said they “never saw the divorce coming,” compared with 14% of women.
• The divorce rate among adults aged 50 and older increased from 4.9 to 10.1 per 1,000 between 1990 and 2010.
• Adults aged 50 and older now account for nearly 40% of divorcing Americans, compared with about 8% in 1990.

Who Initiates Divorce More: Men or Women?

Women initiate more heterosexual divorces than men in the United States. Research by sociologist Michael J. Rosenfeld found that women initiated about 69% of heterosexual marital breakups, compared with 31% initiated by men.

In simple terms, for every 100 heterosexual marital breakups studied, about 69 were wanted more by the wife, while 31 were wanted more by the husband. The gender difference was much smaller among unmarried heterosexual couples, suggesting that the pattern may be more closely linked to marriage than to romantic relationships in general.

Divorce Initiation by Gender and Relationship Type

The difference in divorce initiation becomes more complex when different types of relationships are considered. Research by Michael J. Rosenfeld found a clear gender gap in heterosexual marriages, with women more likely than men to want the relationship to end. 

However, this pattern was not found to the same extent among unmarried heterosexual couples, where men and women were much more evenly matched in initiating breakups. Same-sex marriages require a different approach because there is no husband-versus-wife comparison. Researchers generally compare divorce rates between female same-sex couples, male same-sex couples, and different-sex couples.

A Finnish study that followed more than 450,000 couples found substantial differences in divorce rates over a 10-year period:

These figures represent the results of a specific Finnish study and should not be interpreted as global divorce rates. Divorce patterns can vary depending on the country, marriage cohort, length of follow-up, legal environment, and research methodology.

Top Reported Causes of Divorce

75% Report Lack of Commitment as the Most Common Contributor to Divorce

Lack of commitment was reported by 75.0% of divorced participants as a major contributor to the end of their marriage, making it the most frequently cited factor in the study. This means 3 out of every 4 participants identified commitment problems as a major issue.

Source: PubMed Central (PMC)

The finding suggests that long-term relationship investment, willingness to compromise, and efforts to maintain the marriage were important factors in this sample.

59.6% Identify Infidelity as a Major Contributor to Divorce

Infidelity or extramarital affairs was identified by 59.6% of respondents as a major contributor to divorce. This means that nearly 6 in 10 participants reported an affair as an important factor in the breakdown of their marriage.

Infidelity can damage trust and relationship stability, although it may occur alongside other problems such as conflict, dissatisfaction, and communication difficulties.

Nearly 3 in 5 Respondents Link Excessive Conflict to Divorce

Excessive conflict and arguing was reported by 57.7% of participants, placing it third among the major contributors examined in the study.

In other words, nearly 3 in 5 respondents identified persistent conflict as an important factor in their divorce. The finding refers to ongoing or excessive conflict rather than ordinary disagreements between spouses.

45.1% Report Early Marriage as a Factor in Divorce

Getting married too young was identified by 45.1% of respondents as a contributor to divorce. This represents about 4.5 in every 10 participants in the study.

Early marriage can coincide with major changes in education, careers, finances, parenthood, and personal expectations, which may affect relationship stability over time.

36.7% Says Money Problems as a Key Factor in Divorce

Financial problems were identified by 36.7% of participants as a major contributor to divorce. This means that more than 1 in 3 respondents reported money-related difficulties as an important factor.

Financial problems can include disagreements about spending, debt, saving, employment, financial independence, and household expenses. Financial stress may also increase tension caused by other relationship problems.

34.6% Identify Substance Misuse as an Important Factor in Divorce

Substance abuse was reported by 34.6% of divorced participants as a contributor to the end of their marriage. That is approximately 1 in 3 respondents in the study.

Substance misuse can affect several areas of married life, including finances, employment, parenting, trust, communication, and household stability.

Domestic Violence Contributed to Divorce for 23.5% 

Domestic violence was identified by 23.5% of participants as a major contributor to divorce. This represents nearly 1 in 4 respondents in the study.

Domestic violence is distinct from ordinary marital conflict and can involve physical violence, intimidation, coercion, or controlling behavior. The study also identified domestic violence among the events that could act as a final trigger for ending a marriage.

Around 18.2% of Respondents Link Health Issues to Marriage Breakdown

Health problems were reported by 18.2% of participants as a contributor to divorce. This is equivalent to about 1 in 5 respondents.

Health-related difficulties can place additional emotional, practical, and financial pressure on a marriage. However, this figure reflects the participants’ own reports and does not establish that health problems directly caused their divorces.

About 1 in 6 Respondents Link Lack of Family Support to Divorce

Lack of family support was identified by 17.3% of participants as a contributor to divorce. This means that about 1 in 6 respondents reported insufficient support from family members.

Family relationships can affect a marriage through emotional support, disagreements, expectations, childcare responsibilities, and other forms of involvement.

13.3% Say Religious Differences Played a Role in Their Divorce

Religious differences were reported by 13.3% of participants as a contributor to divorce. This represents about 1 in 8 respondents.

Differences in religious beliefs can sometimes create disagreements about values, family traditions, child-rearing, holidays, and other aspects of married life.

13.3% Identify Insufficient Premarital Education as a Factor in Marriage Breakdown

Little or no premarital education was identified by 13.3% of respondents as a contributor to divorce. This is also about 1 in 8 participants.

Premarital education can provide couples with tools for communication, conflict management, financial discussions, and relationship expectations. However, this study does not establish that the absence of premarital education directly causes divorce.

Divorce Causes by Gender

Men Are More Likely to Say the Divorce Was Unexpected

AARP research involving midlife and older adults found a notable gender difference in how people experienced divorce. Men were more likely than women to say they did not expect the divorce.

The pattern suggests that dissatisfaction may become actionable at different points for husbands and wives. That does not mean women necessarily experience more marital problems. It means women appear more likely in several studies to convert dissatisfaction into a decision to end a heterosexual marriage.

Possible Factors Behind the Gender Difference

Researchers have proposed several factors that may contribute to differences in how men and women experience divorce. These include:

• Household and childcare responsibilities: Differences in how couples divide domestic and parenting responsibilities may affect marital satisfaction.
• Emotional expectations: Husbands and wives may have different expectations about emotional support, communication, and intimacy.
• Financial independence: Greater financial independence may make it easier for some women to leave an unsatisfying marriage.
• Changing expectations of equality: Expectations about equal responsibilities and decision-making within marriage have changed over time.
• Different relationship thresholds: Spouses may differ in how long they remain in an unhappy or difficult relationship before considering divorce.
• Recognition of marital problems: Partners may recognize or respond to serious relationship problems at different stages.

Gray Divorce Statistics 

What Is Gray Divorce?

Gray divorce generally refers to divorce among adults aged 50 and older. It has become an important demographic trend in the United States, particularly because the number and share of older adults experiencing divorce have increased substantially over the past several decades.

Research by Susan L. Brown and I-Fen Lin found that the U.S. divorce rate among adults aged 50 and older more than doubled between 1990 and 2010. The rate increased from approximately 4.9 divorces per 1,000 married people aged 50 and older in 1990 to 10.1 per 1,000 in 2010.

Source: The Gray Divorce Revolution – PubMed Central

This represents an increase of approximately 106%, meaning the divorce rate among adults aged 50 and older more than doubled during the 20-year period.

Number of Gray Divorces Also Increased

The number of Americans aged 50 and older experiencing divorce increased substantially during the same period. Research estimated that approximately 206,000 adults aged 50 and older divorced in 1990, compared with about 643,000 in 2010.

That represents an increase of approximately 437,000 divorcing adults, or about 212% over the 20-year period.

Nearly 40% of Divorcing Americans Are Now Age 50 or Older

A 2024 research shows an important change in the pattern. The gray-divorce rate itself has largely plateaued, with some evidence of a decline among adults aged 50 to 64. However, adults aged 50 and older now make up a much larger share of the overall divorcing population.

In 1990, only about 8% of people who divorced were aged 50 or older. Today, adults in this age group account for nearly 40% of divorcing Americans.

This shows gray divorce is no longer increasing at the same rate seen during the 1990s and 2000s, but older adults represent a much larger proportion of people going through divorce than they did several decades ago.

Population aging plays an important role in this shift. As the U.S. population has become older, more people are reaching their 50s, 60s, and beyond while still being married. This has increased the number of older adults who are part of the U.S. divorce population.

Why Is Gray Divorce More Common Than It Used to Be?

There is no single reason why gray divorce has become more common. Instead, several demographic, economic, and social changes have occurred at the same time and have changed how people approach marriage later in life.

1. Longer Life Expectancy Makes Later-Life Divorce More Feasible

People are living longer than previous generations, which changes the meaning of divorce after age 50. Someone who ends a marriage at 55 may still expect to live for several more decades. This can make the decision to leave an unhappy or unfulfilling marriage different from what it would have been when life expectancy was shorter.

2. Social Attitudes Toward Divorce Have Changed

Divorce carries less social stigma than it did in previous generations. As divorce has become more socially accepted, older adults may face less pressure to remain in marriages that no longer meet their expectations.

3. Greater Economic Independence Can Make Divorce More Feasible

Women’s increased participation in paid employment and greater access to their own income and financial resources may also make leaving an unhappy marriage more financially possible.

Economic independence does not necessarily cause divorce, but it can reduce one of the practical barriers to ending an unsatisfying marriage.

4. Remarriage Is Linked to Higher Divorce Rates

Remarriage is one of the strongest statistical factors associated with divorce among adults aged 50 and older. Brown and Lin found that the divorce rate for people aged 50 and older was 2.5 times higher among those in remarriages than among those in first marriages. 

The reported rates were 17.2 divorces per 1,000 married people in remarriages, compared with 6.9 per 1,000 among people in first marriages.

FAQs

1. Do Women Initiate Most Divorces?

Yes, research shows that women initiate approximately 69% of heterosexual marital breakups in the United States, compared with about 31% initiated by men. This gender difference is much smaller among unmarried heterosexual couples.

2. What Is the Number One Cause of Divorce?

There is no universal number-one cause of divorce because studies use different samples and methods. In one study of 52 divorced individuals, lack of commitment ranked first at 75.0%, followed by infidelity at 59.6% and excessive conflict at 57.7%. These figures apply to that specific study sample and do not represent all U.S. divorces.

3. Is Infidelity the Most Common Reason for Divorce?

Not in every study. In the Scott et al. study, 59.6% of participants identified infidelity as a major contributor, making it the second-most reported factor after lack of commitment. However, infidelity was also commonly reported as a final trigger that led to the end of a marriage.

4. What Are the Most Common Reasons Couples Divorce?

Commonly reported contributors include lack of commitment, infidelity, persistent conflict, marrying young, financial problems, substance abuse, and domestic violence. These factors often overlap, meaning one divorce can involve several problems at the same time. Research therefore generally avoids assigning every divorce to one single cause.

5. What Is Gray Divorce?

Gray divorce generally refers to divorce among adults aged 50 and older. The U.S. divorce rate for this age group more than doubled from 4.9 per 1,000 married people in 1990 to 10.1 per 1,000 in 2010. Adults aged 50 and older now account for nearly 40% of divorcing Americans, compared with about 8% in 1990.

6. Are Second Marriages More Likely to End in Divorce?

Yes, among adults aged 50 and older, Brown and Lin found that the divorce rate was 2.5 times higher among people in remarriages than among those in first marriages. The study reported 17.2 divorces per 1,000 for remarried adults compared with 6.9 per 1,000 for those in first marriages.

Wrapping Up

These divorce statistics show that marriage breakdown is rarely explained by one factor alone. Women initiate about 69% of heterosexual marital breakups, while lack of commitment, infidelity, persistent conflict, financial problems, and other issues are frequently reported among divorced participants. 

Divorce patterns also vary by relationship type and age, with research showing different outcomes among same-sex and different-sex couples and a growing share of divorces involving adults aged 50 and older. The rise of gray divorce highlights how changing life expectancy, social attitudes, financial independence, and remarriage patterns can influence divorce later in life. However, these statistics should be interpreted carefully because studies use different populations, definitions, and methods.
