How Many Marriages End in Divorce? Understanding the Modern Divorce Landscape 

Divorce has long been a cultural touchpoint and a legal milestone — and in recent years, it’s also become a subject of growing curiosity. People want to know: how many marriages end in divorce today? How do we compare to past generations? What’s driving the decline in divorce rates? And what does it mean for couples in Illinois? 

This guide explains the most recent divorce statistics, evolving causes of marital breakdown, how remarriages and money issues play a role — and what you can do to protect your relationship and your legal rights. 

 

Divorce in America: A 70-Year Trend 

From taboo to common — then slowly back down again. 

A line chart titled “Estimated % of Marriages Ending in Divorce by Decade (U.S.)”. The x-axis represents decades from the 1950s through the 2020s, and the y-axis shows divorce rates as percentages, ranging from 0% to 60%. The line starts low in the 1950s at about 11%, rises sharply in the 1960s to about 22%, peaks in the 1970s at 45%, and reaches its highest point in the 1980s at about 48%. Afterward, it gradually declines: around 46% in the 1990s, 42% in the 2000s, 39% in the 2010s, and down to 36% in the 2020s. The overall trend shows a steep rise mid-century followed by a slow decline since the 1980s.

1950s: Divorce was rare. Only about 10% of marriages ended in separation. Strict gender roles, religious norms, and social stigma kept most couples together. 

1970s–1980s: Divorce rates soared to nearly 50%, fueled by: 

  • The no-fault divorce revolution 
  • Growing women’s economic independence 
  • Cultural acceptance of separation as a personal choice 

1990s–2000s: Rates stabilized at 45–50% nationwide. 

2020s: Today, approximately 39% of marriages end in divorce — and the trend is slowly declining. Millennials and Gen Z marry later, often with stronger communication tools and shared responsibilities. 

 

Is Divorce Still Common in Illinois? 

In Illinois, the divorce rate closely mirrors national averages but with some regional variations. 

According to recent public records: 

  • Illinois had 23,000+ divorces filed in 2020 
  • Chicago and Cook County account for a large share due to population density 
  • Remarriage and blended family dynamics are increasingly common 

While national trends show a dip, Illinois divorce courts remain active, especially in urban and suburban communities. 

 

Why Are Fewer Marriages Ending in Divorce Today? 

Modern couples are approaching marriage with more caution and intention. Several factors contribute to the falling divorce rate: 

  • Later marriage ages (30+ on average in the U.S.) 
  • Increased cohabitation before marriage 
  • More relationship education and premarital counseling 
  • Higher rates of financial planning and joint decision-making 

That said, second and third marriages still carry a higher risk of divorce, especially without legal preparation like premarital and postnuptial agreements. 

Common Reasons for Divorce in 2024 

Despite declining numbers, divorce remains a reality for many. Based on national research and client experiences, the most frequently cited causes include: 

  • Lack of commitment 
  • Frequent arguing and poor conflict resolution 
  • Infidelity or breach of trust 
  • Substance abuse 
  • Incompatibility 
  • Money issues, such as: 
  • Financial infidelity (e.g., secret accounts or debt) 
  • Disagreements over spending/saving 
  • Unequal financial contributions 

These issues often lead to emotional strain, resentment, and — ultimately — divorce filings. 

 

Money Problems: A Leading But Underreported Cause 

Financial stress is one of the top predictors of divorce, but it’s often masked by other surface-level complaints. Many couples separate due to: 

  • Hidden spending or debt (aka financial infidelity) 
  • One partner controlling finances 
  • Major income disparity or job loss 

In Illinois, financial disclosures are a key part of divorce proceedings — and your attorney can help uncover hidden liabilities or assets early in the process. 

 

What About Divorce in Second and Third Marriages? 

  • Second marriages have a divorce rate around 60–67% 
  • Third marriages fail at even higher rates — up to 73% 
  • Causes often include: 
  • More complex family structures 
  • Blended children and parenting conflicts 
  • Financial baggage from previous relationships 

Prenuptial or Postnuptial agreements can help protect both partners and reduce future disputes. 

 

Prenuptial Agreements: A Rising Trend 

Many couples now sign prenuptial agreements — contracts created prior to marriage that outline expectations for finances, property, and spousal support. These legal tools help: 

  • Prevent conflict over assets 
  • Clarify financial obligations 
  • Protect individual property in case of divorce 

They’re especially common in second marriages or when one partner owns a business or receives an inheritance. 

 

Thinking About Divorce in Illinois? Here’s What to Know 

If you’re in Illinois and contemplating divorce, it helps to: 

  • Review your legal rights and obligations 
  • Understand Illinois’s no-fault divorce laws 
  • Consider mediation or collaborative divorce for less adversarial solutions 

You don’t have to do this alone.
