Family dynamics are evolving dramatically. The global trend shows a rise in the number of childless individuals, with families increasingly opting for just one child.
The “one-child family” is becoming more common, potentially setting the stage for it to become the new standard in the future.
Factors such as economic uncertainty, escalating childcare costs, shifting gender roles, and the growing trend of women having children later in life — combined with environmental concerns — foster the perception that raising more than one child is challenging or even unfeasible.
As of 2022, 44% of households in the UK included only one child, compared to 41% with two children. Similarly, in the EU, 49% of families have just one child.
Unlike previous generations, where larger families were the norm, this shift is globally recognized. The global birth rate has plummeted from an average of 5 children per woman in 1960 to 2.3 children in 2020, with no end in sight for this downward trend.
Should we be concerned about the well-being of only children? Contrary to popular belief, they do not suffer from social isolation or undue entitlement. In fact, having one child may ultimately provide better outcomes for families.

The Hidden Truth About Only Children
“It’s a widely acknowledged fact that only children are thriving,” says Susan Newman, a renowned parenting expert and social psychologist. “This should prompt parents who feel pressured to have more kids, especially those from earlier generations.”
Newman emphasizes how entrenched these stereotypes are, equating them to sexism and ageism, but also expresses hope that we are breaking free from the unjust stigma.
To trace the roots of the concept of only child syndrome, we revisit 1896 when child psychologists G. Stanley Hall and E.W. Bohannon studied the traits of only children. Their findings suggested a plethora of negative characteristics, branding only children as lonely, bossy, and spoiled — a notion that has perpetuated stereotypes to this day.
Despite criticism of this early research, its influence persists, overshadowing more recent studies that highlight the advantages of being an only child.
Dr. Adrian Mancillas, author of Challenging Stereotypes About Only Children, states that “research consistently shows that only children perform comparably to those with siblings in various social and personality metrics, with no notable behavioral discrepancies.”
While some only children may exhibit traits identified in the 1896 study, these characteristics can also be present in children with siblings. Ultimately, parental influence supersedes sibling presence in determining childhood happiness and social stability.

That said, there are unique aspects to consider. “Only children receive their parents’ full attention and resources, while avoiding sibling rivalry,” explains Mancillas. However, such intense relationships may expose children to parental stress more acutely than those with siblings may experience.
What about the experiences of only children as they transition into adulthood? Studies indicate that those who grew up as only children often reflect positively on their childhood.
Newman refers to this phenomenon as a “one-child dynasty,” noting that only children are frequently inclined to have only one child as well.
The Rising Trend of One-Child Families
Could the uptick in one-child families signal a successful debunking of detrimental stereotypes? Newman identifies several factors contributing to this one-and-done trend.
“Women are increasingly starting families later, pursuing higher education and stable careers, significantly reshaping their life priorities,” she notes.
“Family structures are diversifying, with more single parents and individuals opting for adoption or IVF, redefining what it means to be a family today.”
As traditional gender roles evolve, so too does the notion of family. The practical aspects of having one child cannot be overlooked; by 2023, the expected cost of raising a child stands at £166,000 for married couples and £220,000 for single parents.

Environmental concerns are also a prominent factor. As awareness of climate issues rises, many choose to have fewer children to minimize their family’s carbon footprint.
However, the benefits of having only one child extend to parents as well. Research indicates that parents with one child report greater happiness. But the second child can significantly reduce overall happiness, and studies suggest happiness gains diminish with subsequent children.
This trend is particularly notable in the UK, US, and Canada, where parental support systems are less robust than in places like Germany, where free public childcare is available, and Romania, which provides extended parental leave.
As we look to the future, could the one-and-done trend persist? While birth rates are on the decline, many may find that being part of a one-child family leads to greater financial security and personal freedom. Ultimately, it appears only children are thriving.
