What Is the Birth Rate Issue?
Over the past several decades, fertility rates have fallen sharply around the globe. In most Western countries, including the U.S., the total fertility rate (TFR)—the average number of children a woman will have—has slipped below the replacement level of 2.1.
Today, the U.S. stands at approximately 1.62 births per woman, the lowest since national records began in the 1930s (Our World in Data)(WSJ). With more than 60% of the world now living in low-fertility countries, this isn’t just a national concern—it’s a global demographic transformation.
A Closer Look at the Post-War Baby Boom
The Surge in Births After WWII
Between 1946 and 1964, the U.S. experienced an extraordinary spike in births, with the fertility rate averaging around 3.5 to 3.7, peaking at 3.77 in 1957 (Wikipedia).
This era produced roughly 78 million boomers in the U.S. alone (Wikipedia).
Why the Boom Happened
Pent-up demand: Soldiers returning home and delayed marriages from wartime created a surge in family creation.
Economic prosperity: The post-war economy entered a golden era of growth—high wages, booming industry, and affordable housing (suburban developments expanded massively) encouraged young families to grow (Works in Progress) (Wikipedia).
Labor market effects: As women leaving wartime jobs returned home, research suggests that reduced female labor participation indirectly raised fertility, because married women had fewer career alternatives compared to their mothers (World Economic Forum)(NBER).
Social norms & marriage boom: Marriage rates rose, and a larger share of women progressed to having second and third children—a cultural shift aligned with stability and structured suburban life (Wikipedia).
This “perfect storm” of economics, social norms, and demographic timing fueled a dramatic—but temporary—uptick in births.
The Mid-20th Century Decline & the 2008 Turning Point
Slow Decline After the Boom
By the early 1970s, the fertility rate dropped below replacement: 2.0 by 1973, and continued to fall throughout the 20th century (NBER)(Our World in Data). Globally, TFR went from more than 5 children per woman in the 1950s to less than 2.5 by the 2000s (Our World in Data).
Key drivers included improved access to contraception, career opportunities for women, rising education levels, and urbanization.
The Impact of the 2008 Financial Crisis
Before 2008, U.S. birth rates remained relatively stable for decades. After 2007, they dropped sharply—despite moderate economic recovery, births fell from 69.3 per 1,000 women (2007) to 55.8 in 2020, a near 20% decline (Econofact) (Pew Research Center.) Pew Research attributed the timing to economic uncertainty, job loss, home foreclosures, and massive debt burdens that made having children financially untenable (Pew Research Center) (Stanford Poverty Center.)
Where Birth Rates Stand Today
The U.S. TFR hovers around 1.62–1.63 in 2023–2024, with roughly 3.6 million births per year—16% fewer than in 2007 WSJ. Globally, the trend persists: over 60% of nations are below replacement, with several like Japan and South Korea near 1.1 births per woman, and Europe averaging 1.4–1.6 (Our World in Data The Times).
Birth rates remain stubbornly low, and current demographics suggest no quick rebound.
Voices Advocating for More Births—and Why a Decline Might Not Be Problematic
The Pro-Birth Argument
High-profile figures like Elon Musk and some policymakers warn that population collapse threatens economic vitality and social systems. Some countries have even implemented baby bonuses, tax credits, and housing incentives—though effects are limited when financial stressors remain high (The GuardianBusiness Insider). But perhaps the opposite is exactly what we need in the world today. Can a birthrate decline bring about positive outcomes for the country, and the world, as a whole?
Reasons Why a Lower Birth Rate Might Be Beneficial
Reason 1: Environmental & Resource Relief
Fewer births mean lower carbon emissions, reduced depletion of natural resources, and decreased pressure on land and ecosystems.
A 1% rise in population results in approximately a 1.28% increase in carbon emissions.
More births would drive demand for housing, food, water, and energy, accelerating deforestation and biodiversity loss.
Global population growth could push emissions 10% higher by 2080, worsening climate change if not offset by major technology shifts.
Per capita CO₂ emissions in developed countries average 6.6 metric tons annually — one additional child adds up to 50+ tons per decade.
If birth rates rise significantly, resource scarcity and climate instability are projected to worsen, undermining sustainability efforts over the next 25–50 years.
Reason 2: Aligning with Economic Reality
Given the $300k+ cost per child, fewer children often reflects responsible planning in high-cost environments.
Many families choose one child or none due to financial constraints—27% of recent homebuyers include children, compared to 58% in 1985 (New York Post).
Reason 3: AI + Demographic Trends
AI will reshape work: 14% of workers already displaced; nearly 10% of female-dominated jobs at risk (seo.aiReuters).
McKinsey projects up to 29% of work hours in regions like NYC will be affected by generative AI by 2030 (McKinsey & Company).
If AI handles many jobs, producing more children into a shrinking labor market may lead to unemployment—not prosperity.
As Geoff Cubitt notes, AI challenges the traditional need for population growth to drive economies (Law & Liberty).
Reason 4: Lower Births = Social Stability
Fewer people mean less competition for jobs, housing, and resources.
Pilot Universal Basic Income (UBI) programs—like Stockton’s $500/month—show improved mental health and reduced poverty (Wikipedia) (The US Sun).
With fewer citizens, systems like UBI, free healthcare, and universal housing become financially feasible, reducing inequality and boosting stability.
Reason 5: Social Security Sustainability
Though fewer workers raise retirement system alarms, Social Security strain is driven more by financial mismanagement than demographics.
A smaller population with adequate automation (AI caregivers, automated services) could allow for more efficient resource distribution—yes, it edges into socialism, but it may also be a necessary adaptation.
Reason 6: Housing & Urban Simplicity
With fewer families, the demand for housing decreases — easing the supply shortage and reducing sprawl.
Cities could refocus on sustainable development rather than constant expansion.

The Gen Z Reframe: Quality Over Quantity
Gen Z isn’t rejecting family—it’s reshaping it. And that’s not defeat, it’s evolution:
“One-and-done” parenting is on the rise: childraising costs of $15k–$17.5k/year drive families to choose a single child (Parents).
Many prioritize mental health, community, and planetary impact over traditional family structures.
“Care for the children we have — and each other — before bringing more souls into this world” isn’t pessimism—it’s progress.
Final Thoughts: A Smarter Future Starts Here
The birth rate decline isn’t a crisis—it’s a recalibration. Instead of longing for a return to 1950s norms, Gen Z is pushing us to imagine a humane, equitable world. One where fewer children means:
More attention to mental health
Sustainable resource use
Smart AI integration
Social systems that work for everyone
Maybe fewer is better—and the legacy Gen Z builds will ensure the world we do pass on is worth living in.
