The Real Reason Marriage Rates Are Declining: An Economist's Perspective

The Marriage Market Narrative

• 💡 The popular narrative that college-educated women are too picky and unwilling to marry men with less education is not supported by data.
• 🎯 While college-educated women's marriage rates have remained stable, this is largely because they are increasingly marrying men without college degrees.

Declining Marriage Rates for Less Educated Women

• 📉 Marriage rates have significantly declined for women with the least education, dropping from roughly 79% for those born in 1930 to just over 50% for those born in 1980.
• ⚠️ This decline is linked to difficulties in finding a suitable partner, particularly in areas with higher rates of joblessness and incarceration among men.
• 🏠 Cohabitation has not significantly offset these declining marriage rates in the U.S.

Assortative Mating and Inequality

• 🤝 Economists observe positive assortative mating, where individuals tend to partner with others who are similar in characteristics like income and education.
• 📈 This pattern can exacerbate income inequality across generations, as high-earning parents are more likely to have high-earning children.
• 📊 The collective influence of partner selection has been shown to significantly impact household income inequality, potentially increasing the Gini coefficient.

The Role of Education and Economics

• 🎓 Marriage rates for college-educated women have remained stable, while rates for those without a 4-year degree have sharply declined.
• 💰 For non-college-educated men, a significant factor in declining marriage prospects is a real decline in earnings over the past 50 years.
• 📍 Geographic areas with higher employment and lower incarceration rates for non-college-educated men show smaller marriage gaps between college and non-college-educated women.

Marriageability and Modern Challenges

• 🛠️ A simplified economic definition of marriageability for non-college men (above median earnings, not married to a college woman) shows a dramatic decrease from 70% in the 1930 cohort to around 35% in the 1980 cohort.
• 📉 Factors beyond economics, such as addictions, incarceration, and early life mortality, also affect the marriageability of some men.
• 🌐 While dating apps may expand the dating pool, their impact on matching across different educational or class lines is still under investigation, with concerns about algorithmic dynamics and male-female match inequality.

Policy Implications

• 🎯 Addressing declining marriage rates among less educated populations requires focusing on factors like male employment and incarceration rates.
• 🧩 The patterns of educational and class polarization are evident not only in marriage markets but also in labor markets, education, and political ideology.
• 🤔 While marriage offers benefits, forcing individuals into marriage when they are unable to find a suitable partner may not be beneficial, and the impact on children of marginal marriages requires further research.
