For young people today, the question of whether to have kids feels more open than ever, and the answer isn’t clear-cut. Many feel torn; imagining themselves in traditional parental roles can be hard, and excitement about that future is often mixed with hesitation. Yet, even for those not actively dreaming of family life, the thought of a childless old age brings its own concerns. Some are motivated by the idea of passing on their values, though they know that children can grow up to embrace entirely different beliefs. The decision is a weighty one, shaping not only their own lives but also the life of someone yet to be born.
In the last two decades, birth rates have sharply declined across the developed world, reshaping the economic, social, and cultural landscapes of entire nations and sparking serious debates about the future. The reasons are complex, with rising child-rearing costs, lifestyle changes, economic pressures, and shifting cultural attitudes toward family all playing a role. Meanwhile, looking at China’s looming demographic time bomb, widely discussed in the media, it’s easy to see why concerns about birth rates have risen to the forefront globally. The implications of a shrinking younger population are vast, affecting labour markets, social security systems, and societal structures. Exploring the factors driving this trend—and the potential impacts if it continues—provides insight into the evolving reality of parenthood in the 21st century.
One of the most direct reasons behind falling birth rates is that having children has simply become prohibitively expensive. In the United States, the estimated cost of raising a child to age 18, excluding college, exceeds $300,000—and rises significantly when education and healthcare are included. Factoring in college and additional inflation adjustments, the cost can easily reach $1 million. In the United Kingdom, figures are similar, with average expenses exceeding £220,000 for a single parent as of 2023. In 2022, the average cost ranged from £157,562 for couples to £208,735 for single parents, but in 2023 these figures rose to £166,000 and £220,000, respectively. Additionally, childcare costs in the US have grown at nearly twice the rate of inflation, with similar rises in the UK where childcare alone consumes over 20% of an average British couple’s income. High child-rearing costs leave many millennials and Gen Zers questioning whether they can afford children at all, much less multiple children, as previous generations often did.

This financial squeeze is compounded by stagnant wages, high student debt, rising housing prices, and record-high credit card debt. Millennials and Gen Zers, who make up the majority of today’s potential parents, face a financial landscape far different from that of their parents. In Britain, for instance, over half of those under 40 are renters, a statistic that has doubled in just one generation. Owning a home is increasingly seen as out of reach, which has led many to delay or opt out of starting families altogether.
Historically, large families were seen as an economic asset. Up until the early 20th century, much of the world’s population lived rural lives, closely tied to agriculture or small-scale family-run businesses. Having more children meant additional hands to help with farm work or family enterprises, making children integral to family and community economies. The Industrial Revolution initiated urbanisation on a large scale, but it wasn’t until after World War II that urban migration and modern economic shifts truly took hold. In the post-war era, families increasingly moved to urban areas, where economic opportunities often required fewer hands-on family members, and traditional family structures began to evolve.
The baby boom of the mid-20th century, combined with rapid economic growth and the “Green Revolution,” fostered the development of a strong middle class across the developed world. In the 1950s, birth rates in the UK peaked at around 3.7 children per woman, reflecting an era when family structures were larger and often financially secure. However, following the 2008–2009 financial crisis, income inequality surged, with wealth consolidating among the top 1%. This erosion of the middle class has left today’s families in a position that some compare to the Victorian working class: struggling to maintain purchasing power, facing job insecurity, and increasingly unable to afford children. This shift has contributed to the decline in birth rates in nations like Japan, Italy, Germany, and South Korea, which now record some of the lowest birth rates worldwide.

Modern society is also experiencing profound shifts in cultural attitudes toward family and parenthood. A US study from 2003 showed that 83% of people surveyed expressed a desire to become parents, but by 2024, that figure had fallen to 51%. In Canada, only 7% of adults in 2001 reported they didn’t want children, yet by 2022, that number had risen to 34%. This shift reflects broader changes in how younger generations define happiness, fulfilment, and personal success. Today, many young adults prioritize career satisfaction, travel, friendships, and other life experiences over traditional milestones like marriage and parenthood. Currently, only 26% of people consider parenthood essential to a fulfilling life, compared to 71% who prioritize career satisfaction and 61% who view close friendships as central to their happiness.
This reluctance to have children isn’t solely due to financial strain. It also reflects new lifestyle choices, with many people opting for experiences over family obligations. Today’s young adults, having witnessed their parents’ financial struggles and high levels of work-related stress, are questioning traditional life paths. Dual-income, no-kids (DINK) families are on the rise, and many individuals find fulfilment outside of family life. For instance, studies in Canada and European nations, such as Germany and the UK indicate that couples without children report slightly higher levels of overall happiness, possibly because they face fewer financial and logistical stresses than parents.
Compounding these shifts in family planning is a change in how people meet and form long-term relationships. While dating apps have made it easier than ever to connect, they’ve also introduced challenges that impact relationship stability and satisfaction. Pew Research recently found that 75% of people felt it was either somewhat or very difficult to find a compatible partner, with burnout from constant swiping and shallow interactions being major deterrents. The pressure for instant connection and the constant availability of new “matches” can lead to superficial dating patterns, making it harder to form long-lasting relationships—a significant barrier for those considering parenthood.

According to studies conducted by organizations like the American Psychological Association, social media and dating apps contribute significantly to elevated stress and anxiety levels among users. Dating app users report feeling nearly three times more stressed than those who don’t use these platforms. Authentic connections often feel out of reach, as research reveals that 1 in 5 users lie about their age, 1 in 7 about their income, and 1 in 8 about their job. This culture of “surface-level marketing”—where individuals present idealized or selectively curated versions of themselves to appear more attractive, focusing on superficial qualities rather than fostering genuine connections— has led to widespread disillusionment with relationships. This phenomenon negatively impacts mental health and contributes to delays in forming families.
As family sizes shrink and fewer people enter the workforce, we might see echoes of historical patterns. As a historical case study, the population decline in Europe following the Black Death illustrates how labour shortages can shift economic power. With half the population lost, the surviving working class had leverage to demand higher wages and better conditions. This scarcity of labour also meant that land and resources were more available, enabling many peasants to acquire property and improve their financial status—a level of prosperity previously out of reach for the lower classes. This redistribution of wealth fundamentally altered Europe’s economic structure, empowering the working class and dismantling rigid hierarchies. Today, some economists suggest that modern labour shortages caused by declining birth rates could prompt similar shifts, potentially redistributing resources and affecting economic structures in unexpected ways.
The economic consequences of low birth rates extend beyond the individual. As populations age and birth rates decline, labour shortages become a pressing issue, impacting everything from social security systems to national economies. Japan, for instance, faces one of the most dramatic examples of this problem. With nearly 30% of its population over the age of 65, Japan has only two working-age people supporting each retiree—a number that is steadily declining. In a healthy, balanced economy, there should ideally be four workers for every retiree. The shrinking ratio forces younger workers to bear a larger financial burden, leading to higher taxes and increased pressure on social welfare systems.

To address labour shortages, many companies are turning to automation, particularly in sectors like manufacturing, retail, and services. In the short term, this can alleviate some pressures, but it also reduces the number of available jobs for younger workers. Companies are increasingly hiring older workers or offering higher wages to attract talent, which drives up business costs and contributes to inflation. As consumer prices rise, wages struggle to keep pace, and the cycle continues.
Governments worldwide are experimenting with policies to encourage higher birth rates, but success has been limited. Taiwan, for example, invested $3 billion in pro-family policies, and France spends roughly 4% of its GDP on family measures, including tax breaks and subsidized childcare. Yet both countries continue to struggle with low fertility rates. Even countries with generous parental leave policies, like Japan and Sweden, report some of the lowest birth rates globally. In Japan, mothers are eligible for up to a year of paid leave at two-thirds of their salary, yet the country’s fertility rate remains low.
This suggests that while financial support and leave policies can help, they don’t address the deeper cultural and economic barriers to parenthood. Experts argue that comprehensive solutions need to encompass broader cultural shifts, including shared childcare responsibilities, supportive work environments, and greater economic security.
Gender inequality in the workplace further discourages many couples from having children. The “motherhood penalty” refers to the earnings gap women experience after becoming parents—a gap that persists long-term. In the United States, only 56% of workers are eligible for 12 weeks of unpaid leave, and women who take leave often see slower career growth. In Britain, mothers are three times more likely to work part-time than fathers, which exacerbates the gender pay gap. The lack of affordable, accessible childcare makes it difficult for many women to return to the workforce after having children, reinforcing a cycle that disincentivises parenthood.
If birth rates continue to decline, the long-term impacts could reshape developed economies. Aging populations, strained healthcare systems, and growing labour shortages will place unprecedented pressure on social welfare systems. Japan’s current demographic challenges are a forewarning for other countries, as nearly a third of its population is over the age of 65, with insufficient younger workers to support them. High taxes, shrinking workforces, and rising healthcare costs will likely drive governments to explore alternative labour sources, potentially turning to increased immigration or aggressive automation.

For those who do choose parenthood, however, the journey remains deeply rewarding. In the US, 82% of parents say having children is enjoyable, though 61% of young people view close friendships as central to their happiness.
As more people choose alternative paths to happiness—whether through careers, friendships, or creative pursuits—society is reimagining what it means to lead a fulfilling life. Declining birth rates signify a cultural shift.
Despite the complexities and challenges, the future of family and society remains filled with possibility. While we face new questions about what our world will look like with fewer births, history reminds us that change often brings unexpected opportunities. After the Black Death, philosopher Jean Froissart observed, “The times were altered for the better.” Labour shortages spurred advancements and empowered those who remained, reshaping societies in ways few could have foreseen.
Today, as we navigate a shifting landscape, the choice to create or redefine family structures remains a deeply personal one. While fewer children may change the traditional workforce and population dynamics, it also opens the door for new social models and ways of living that could bring unexpected resilience and innovation. In the end, our adaptability and desire for connection may well guide us toward a future that—while different—offers its own version of growth and fulfilment.
