The Rise of Singlehood: A Closer Look at the Growing Trend of Unmarried Adults in the U.S. and Worldwide

The landscape of relationships and marriage is undergoing a significant transformation in the United States and across the globe. As we delve into the intricate fabric of societal norms and individual choices, an intriguing trend emerges: an increasing number of adults are choosing to remain unmarried. This blog post explores this phenomenon, compares data from the United States with global trends, and examines the potential implications of this shift.

The U.S. Scenario: A Steady Climb in Singlehood

In the United States, the trend of adults remaining unmarried into their middle years has seen a noticeable uptick. As of 2021, approximately 25% of 40-year-olds had never been married, a significant increase from the 20% recorded in 2010. This shift is more than a mere social change; it heralds a profound alteration in the country’s social, political, and economic landscapes.

Understanding the Global Context

The trend in the U.S. is not isolated. Globally, the average age at first marriage is rising. In Australia and New Zealand, for instance, the average age at first marriage is among the highest: 31.5 for men and 30 for women. Even in regions like Central and Southern Asia, known for younger marriages, men are marrying in their mid-twenties. This delay in marriage contributes to a higher percentage of adults remaining unmarried.

Regional Variations and Cultural Impacts

Different regions exhibit varied trends in singlehood:

  • In Europe and Northern America, the average age of first marriage is 29.6 for men and 27.2 for women, reflecting a preference for establishing careers and personal stability before marriage.
  • In contrast, in regions like Central and Southern Asia, the figures stand at 25.0 for men and 20.8 for women, suggesting cultural and societal inclinations towards earlier marriages.

Divorce Rates: A Contributing Factor

Divorce rates also play a role in the rising number of unmarried adults. In countries like Australia and New Zealand, over 20% of women in their late forties are divorced or separated. This trend is indicative of changing societal norms around marriage and relationships.

Economic and Social Implications

The increasing singlehood has profound implications:

  • Economic Independence: More adults are focusing on their careers and financial independence before considering marriage.
  • Social Dynamics: Traditional family structures are evolving, leading to diverse family forms and living arrangements.
  • Housing and Real Estate: The rise in single-person households influences housing markets and urban planning.
  • Healthcare and Social Security: With more singles, there may be changes in healthcare needs and social security systems.

Gender Perspectives

Interestingly, the trend in singlehood varies between genders. In all regions, men are generally older than women at first marriage. This age gap ranges from 1.5 years in Australia and New Zealand to 4.9 years in Sub-Saharan Africa.

The Future of Relationships

As we look towards the future, it’s clear that the concept of marriage and relationships is evolving. The increasing acceptance of cohabitation, the prevalence of online dating, and the rise of individualistic lifestyles contribute to this trend.


The rise of unmarried adults is a multifaceted phenomenon influenced by economic, social, and cultural factors. As more people in the U.S. and around the world choose to remain single, it’s essential to understand and adapt to these changes. From policy-making to societal norms, this trend impacts various aspects of life, challenging traditional notions of relationships and family.
