On a Thursday evening in almost any upscale restaurant in Chicago, Austin, or Nashville, a pattern emerges once you start looking for it. Tables for two, not four. No booster seats, no urgent negotiations over a children's menu. Just couples, unhurried, working through a tasting menu and a well-chosen bottle of wine, unbothered by the check. These couples have a name: DINKs. Dual Income, No Kids. And the data now confirms they are reshaping the American economy, one deliberately chosen expense at a time.
A Fertility Floor Nobody Predicted
In July 2025, the Centers for Disease Control and Prevention released national birth data showing the US total fertility rate had dropped to 1.6 children per woman, a new record low. The figure continues a near two-decade slide. For context, the fertility rate stood at 2.1 in 2007, which demographers consider the replacement level needed for a population to sustain itself without immigration. The US is now roughly on par with Western European countries that have long grappled with shrinking workforces and straining pension systems.
Leslie Root, a University of Colorado Boulder researcher focused on fertility and population policy, described the trend to the Associated Press as "an ongoing process of fertility delay." Root noted that the US population is still growing overall, since deaths are still outnumbered by births, but the margin is narrowing. The CDC then released provisional data in February 2026 showing that there were approximately 24,000 fewer births in the United States in 2025 than in 2024, the latest downward step in a trajectory that is becoming harder to dismiss as a blip.
Karen Guzzo, director of the Carolina Population Center at the University of North Carolina, summed up the emotional dimension of the data: "Worry is not a good moment to have kids."
The Math Behind the Decision
The financial case for staying childfree has become increasingly concrete. According to a November 2025 study by SmartAsset, the average annual cost of raising a child under five in the United States reached $27,743 in 2025. That figure covers additional housing, food, transportation, healthcare, and childcare for a working couple. It rose 4.5% between 2024 and 2025, slightly above the 2.82% general inflation rate for the same period. In Massachusetts, the highest-cost state, that annual figure has crossed $44,000, meaning two working parents in Boston need to earn at least $124,842 combined just to cover themselves and one preschooler.
The lifetime number is even starker. The USDA estimates the total cost of raising a child from birth through age 17 at approximately $310,000 for a median-income family, and that figure does not include college tuition, room, or board. Research cited by CBS News in 2024 found that parents typically spend about $240,000 per child from birth to age 18, a figure that itself represents a 20% increase from 2016.
Childcare alone is consuming a significant portion of household income. The average family spends $700 a month on childcare, according to MassMutual. That is more than the monthly mortgage payment in many American cities a decade ago. In major metro areas, licensed infant daycare can run $2,000 or more per month, which exceeds median rent in most of the country.
What Young Adults Are Actually Saying
In September 2024, MassMutual surveyed 1,000 American adults and found that approximately 23% of millennials and Gen Z adults between 18 and 43 who do not have children cited financial motivations as the reason they plan to remain that way. The two main drivers were, first, valuing the financial freedom that comes from not having kids, and second, concern about their ability to afford raising children at all.
Paul LaPiana, a certified financial planner and head of brand, product, and affiliated distribution at MassMutual, framed the tension plainly: "Raising a family is a financial commitment. It has always been. We are all faced with choices every day, and there is likely room for improvement when it comes to balancing decisions about immediate gratification with long-term happiness and financial security."
Pew Research conducted a separate survey in July 2024 and found similar patterns. Americans under 50 without children were more likely than older generations to cite financial and lifestyle concerns. Those over 50 were more likely to say they simply never had kids because it did not happen, such as never meeting the right partner. The shift in reasoning across generations is notable: what was once circumstance has become, for millions of younger Americans, a deliberate calculation.
The MassMutual data also revealed a troubling picture among parents themselves: 51% of parents said they suffer anxiety due to not having enough money to support their family, and about 4 in 10 parents of children under 18 said having kids had negatively impacted their personal finances.
The DINK Economy
A late 2024 Harris Poll of more than 4,200 American adults put hard numbers on the spending behavior of dual income, no kids households. DINK households represent approximately 5% of all American households. Yet they spend an average of $816 a month on dining alone. The national average for all adults is $215. That is nearly four times more, from a group comprising roughly one in twenty households.
Sixty-one percent of DINK households earn above $100,000 a year. Eighty-eight percent say they use their financial flexibility for personal growth and experiences with their partners. The Harris Poll also found that 79% of DINK couples report a notable financial improvement compared to before living as a dual-income unit without children, and 76% cite their childfree status as key to frequent travel and personal development.
Libby Rodney, chief strategy officer at Harris Poll, described the motivation this way: "Post-pandemic, young couples aren't just combining incomes. They're combining survival strategies." The framing cuts to the core of what researchers note about the DINK phenomenon: what looks from the outside like a luxury lifestyle is, for many couples, a rational response to economic pressure. The USDA's $310,000 lifetime figure makes opting out feel less like a choice and more like an escape hatch.
Between 2016 and 2021, the number of US households without children increased by 643,343, with nearly 100,000 of those being young couples. That trend has continued and, by most indicators, accelerated since 2021 as housing costs surged and student loan relief proved elusive for millions of millennials.
The Policy Disconnect
The political response to declining fertility has been vocal but has not, by most expert assessments, addressed the underlying economics. During the 2024 presidential campaign, both major candidates proposed expanding the federal Child Tax Credit. Vice President Kamala Harris proposed a $6,000 credit for parents of newborns along with a restoration of the expanded pandemic-era credit. Former President Trump's campaign floated a $5,000 credit and later issued an executive order meant to reduce barriers to in vitro fertilization. Trump described himself publicly as the "fertility president."
But the same administration moved to cut funding for social programs that researchers say function as a financial safety net for working people who want families. Guzzo of the Carolina Population Center told reporters that the symbolic gestures around fertility are "not likely to budge things for real Americans," pointing to the gap between headline policy and the structural cost pressures driving behavior.
Harris Poll data offers one nuance that complicates any simple narrative: 65% of Gen Z and millennial DINK couples say they plan to have children eventually. For many of these households, the category is not permanent rejection of parenthood but rather a financial staging area, waiting for the conditions that once made having a family feel possible.
The Longer View
Lower fertility is not historically unique to the United States. The trend has been well documented across Western Europe, Japan, South Korea, and much of East Asia for decades. What makes the current American moment distinct is the speed of the shift relative to housing costs, wage stagnation for younger workers, and the specific economic pressures that arrived in concentrated form after 2020.
SmartAsset's state-by-state data illustrates how unevenly the burden falls. In Mississippi, the most affordable state, the annual cost of raising a young child in 2025 was $19,178, still a significant sum. In Vermont, that figure jumped 25.31% in a single year, from $30,542 to $38,272, the largest one-year increase of any state. New Jersey rose 16.18%. Washington state rose 14.20%. These are not gradual shifts. They are the kind of annual increases that change household calculus in real time.
The $310,000 question is not rhetorical. For the growing share of young American couples running the numbers, the answer is shaping the country's demographic future whether policymakers are ready for it or not.
