How long average marriage lasts is a question many people ask—especially when facing challenges in their own relationships. While some marriages dissolve within just a few years, others last for decades, and the reasons go far beyond love alone. Communication, timing, financial stability, shared goals, and emotional compatibility all influence whether a marriage thrives or ends. When relationships falter, it’s natural to wonder how your experience compares to the norm. Looking at the data helps reveal what contributes to longevity and offers insight into whether your marriage is following a common pattern—or breaking the mold.

The National Average in the United States

According to data from the U.S. Census Bureau and the Centers for Disease Control and Prevention (CDC), the average length of a first marriage in the United States is about 8 years. Some marriages last much longer, while others end within just a few years.

Key Statistics:

• First marriages last an average of 8 years
• About 40 to 50 percent of U.S. marriages end in divorce
• Remarriages tend to last even less time than first marriages
• Couples who marry later in life usually stay together longer

While divorce rates have slightly declined in recent years, that doesn’t always mean couples stay married longer. Some simply delay marriage altogether or cohabitate without tying the knot.

Factors That Affect How Long a Marriage Lasts

No single reason determines how long a marriage will last. Many factors play a role in whether couples stay together or separate.

Age at the Time of Marriage

Couples who marry in their early twenties or younger face higher odds of divorce. Marrying too young often leads to mismatched goals, personal growth at different paces, or financial instability. On the other hand, couples who wait until their late twenties or early thirties tend to enjoy longer marriages.

Education

Couples with higher levels of education tend to stay married longer. Those who both hold college degrees are more likely to build stable relationships. Education can help partners communicate better, manage stress, and handle conflict more effectively.

Income and Financial Stress

Money problems create tension in many marriages. Couples with steady incomes and shared financial goals are more likely to make it through difficult periods. When financial stress builds up, communication often breaks down, and resentment can grow. That’s when many marriages begin to fall apart.

Children

Having children can either strengthen a marriage or strain it. Some couples grow closer when raising children, while others argue more due to parenting conflicts, sleep deprivation, and shifting priorities. Research suggests that marital satisfaction may drop after the birth of a child but can recover over time.

Communication and Conflict Resolution

Marriages often fall apart when couples fail to talk honestly or resolve arguments in healthy ways. When resentment builds and partners stop listening, the relationship starts to erode. Couples who communicate openly and respectfully tend to have longer, more fulfilling marriages.

How Do Divorce Rates Vary by State?

Divorce rates vary widely across the U.S. States with higher poverty levels often report more divorces, while states with stronger social support networks tend to see fewer.

States with higher-than-average divorce rates include:

• Nevada
• Arkansas
• Oklahoma
• West Virginia
• Alaska

States with lower-than-average divorce rates include:

• Massachusetts
• New Jersey
• Illinois
• New York
• California

These numbers reflect more than just individual behavior. Cultural expectations, access to marriage counseling, and local economic conditions all contribute.

Do Remarriages Last Longer or Shorter?

Statistically, second and third marriages last a shorter time than first marriages. Couples who remarry may bring unresolved issues or baggage from previous relationships. There may also be added pressure from blending families or handling finances with children from prior marriages.

Here’s how the numbers look:

• First marriage: average of 8 years
• Second marriage: average of 7 years
• Third marriage: average of 5 years

That doesn’t mean remarriage always leads to another breakup. Some people learn valuable lessons and build stronger partnerships the second time around.

How Has the Length of Marriage Changed Over Time?

Marriage trends have shifted in recent decades. People wait longer to get married now than in previous generations. Many couples focus on building careers, achieving financial stability, or finishing school before settling down.

These delays have contributed to slightly lower divorce rates in younger generations. When people marry later, they usually have more maturity, stronger finances, and better compatibility with their chosen partner.

On the flip side, some people who might have rushed into marriage years ago now choose cohabitation or long-term dating instead. That means fewer marriages, but potentially more stable ones.

Signs That a Marriage May Not Last

While no one can predict the future, certain signs suggest that a marriage may not stand the test of time. These patterns often show up early but get ignored until they become bigger problems.

1. Lack of Communication

When partners stop talking, or only argue, connection breaks down. A strong marriage depends on open, honest conversation.

2. Disrespect or Contempt

If one partner constantly criticizes, mocks, or belittles the other, it signals deeper problems. These behaviors can chip away at love and trust.

3. Financial Secrecy

Keeping secrets about money or making large purchases without discussion often leads to tension. Financial honesty builds trust in the relationship.

4. Emotional or Physical Distance

When partners stop spending time together or grow emotionally cold, it creates a gap that’s hard to bridge later.

5. Infidelity or Lack of Commitment

Cheating can break trust in a marriage. Even emotional affairs or ongoing flirtation can harm the relationship.

Can Marriage Counseling Help?

Marriage counseling doesn’t fix every problem, but it often helps couples communicate better. A skilled counselor can identify patterns that keep causing conflict and suggest practical changes.

Counseling works best when both partners commit to the process. It won’t work if one person refuses to change or continues to act in bad faith. Still, even a few sessions may open up space for better understanding and compromise.

Marriage Doesn’t Come with Guarantees

A marriage certificate doesn’t promise a lifetime of happiness. It’s a commitment that both people must work to maintain. Life stress, illness, career changes, and parenting can all test the strength of a relationship.

Some couples grow together through these challenges. Others grow apart. The way each couple handles life’s shifts has more impact on longevity than the ceremony that started it all.

Final Insights: Average U.S. Marriage Duration & Top Influences

How long average marriage lasts often depends on a mix of personal and societal factors, but in the U.S., the typical first marriage ends around the eight-year mark. While many couples go the distance, others separate much sooner—often influenced by age, education, financial stress, and communication habits. There’s no one-size-fits-all outcome. Some marriages grow stronger with time, while others end in pursuit of personal well-being and growth. Whether your relationship lasts five years or fifty, the quality of that time—marked by respect, empathy, and mutual effort—matters far more than the number of years alone.
