America’s Family Future Is Changing Before Today’s Teenagers Reach Adulthood

Fertility remains historically low, marriage is less common than it was decades ago, and new research suggests many teenagers are uncertain that parenthood will be part of their future.

Long before people have children, they form an idea of whether parenthood belongs in the life they expect to build.

New survey data suggest that expectation is becoming less certain for a meaningful share of American teenagers, particularly girls.

Research highlighted in September by the Survey Center on American Life found significant differences in how teenagers ages 13 to 17 imagine marriage and parenthood. Among secular teen girls in the survey, only 32% said it was very or extremely likely that they would have children. Among religiously active teen girls, the figure was 42%.

Those findings should not be interpreted as a forecast of exactly how many of today’s teenagers will eventually become parents. Preferences change as people age, relationships form and economic circumstances improve or deteriorate.

But the data arrive during a much larger demographic transformation. The question matters because family formation is not merely a private lifestyle trend; marriage, child-rearing and household stability shape communities, schools, labor markets and the lives of children themselves.

America is marrying later, having children later and recording fertility rates far below those seen a generation ago.

Fertility Has Been Falling for Years

The Centers for Disease Control and Prevention reported approximately 3.61 million U.S. births in 2025, down about 1% from 2024.

The general fertility rate fell to 53.1 births per 1,000 women ages 15 to 44, a 23% decline from 2007.

Teen birth rates have fallen even more dramatically, reaching another record low in 2025. The decline in teen pregnancy is widely viewed as having substantial benefits for young women’s educational and economic opportunities, but it also illustrates the scale of the broader shift toward later family formation.

Quarterly CDC data through the second quarter of 2026 continue to give demographers an updated view of those trends, although provisional numbers can be revised.

The bigger story is not a single year’s movement. It is that family formation has changed structurally.

Marriage Is Less Common and Happens Later

Pew Research Center’s 2026 review of long-term American social change found that 50% of U.S. adults were married in 2024, compared with 69% in 1970.

Americans are also much more likely than earlier generations to live with a romantic partner before marriage or instead of marrying.

Pew reported in August that around three-quarters of Americans in their late 30s or early 40s had lived with an unmarried romantic partner at some point.

This does not mean marriage has disappeared as an aspiration. Earlier Pew research found that a large majority of never-married young adults still said they wanted to marry someday.

What has changed is the path to marriage and the timing of it. Greater freedom to delay or reject marriage is a real part of modern life, but so is the possibility that some young adults are postponing a family they actually want because stable housing, relationships or finances feel increasingly out of reach.

Education, housing, employment, dating and expectations about financial stability now interact with family decisions in ways that can push marriage and parenthood further into adulthood.

Teenagers Are Absorbing the World Around Them

The Survey Center on American Life data are especially interesting because teenagers are not making these judgments in isolation.

They are watching adults struggle with housing prices, childcare expenses, work-family balance and relationship instability. They are also growing up in an era when social media provides a constant stream of commentary about dating, divorce, gender conflict and the burdens of parenting.

Religious experience appears to be one factor associated with different expectations.

In the survey, one-third of teenagers said they attended religious services with their families at least weekly, while 27% said they never attended. Religious teenagers were more likely to report regular family meals and frequent in-person socializing with friends.

The research also found differences in how often families explicitly discussed marriage and parenthood.

These associations do not establish that religion causes teenagers to want children. Religious participation is connected to many other characteristics, including family structure, community, parental expectations and social networks.

But the findings reinforce an important point: expectations about family life are cultural as well as economic.

Economics Still Matter

It is tempting to explain falling fertility with one simple cause. Reality is less tidy.

Housing affordability can delay independent adulthood. Childcare is expensive. College debt may influence financial decisions. Young adults may prioritize education and careers for longer. Some people do not find a partner with whom they want to raise children. Others simply prefer a life without children.

Pew reported in 2026 that 89% of Americans under 40 said buying a home is harder for young adults today than it was for their parents’ generation.

A person does not need to own a home before having a child, of course. But perceptions of financial insecurity can affect when people feel ready to form families.

Cultural and economic explanations therefore should not be treated as competitors. They can reinforce each other. A culture that values family cannot simply tell young adults to ignore real financial barriers, and economic policy alone cannot create durable relationships or a desire to raise children.

If adulthood feels financially difficult and parenthood is no longer treated as an expected milestone, delaying children becomes easier. And because fertility is biologically time-sensitive, repeated delays can eventually change completed family size even when people originally hoped to become parents.

A Demographic Question Becomes a Cultural One

Falling fertility has implications for Social Security, labor markets, schools, housing and the age structure of the country. Stable families also matter for reasons that are harder to capture in demographic tables: they are one of the primary places where children receive care, expectations, identity and long-term support. Family structure does not determine every child’s outcome, and many families succeed under difficult circumstances, but treating family formation as socially irrelevant would ignore its broader consequences.

But statistics can obscure the human level of the change.

Every birth rate is ultimately the product of millions of personal decisions about relationships, money, health, values and the future.

That makes today’s teenage attitudes worth watching without overinterpreting them.

The important question is not whether a 15-year-old can accurately predict her life at 30. Most cannot.

The question is whether marriage and parenthood still occupy the same place in the imagined American life course that they once did.

The evidence increasingly suggests they do not.

For some Americans, these changes represent expanded freedom to build different kinds of lives. For others, they raise a legitimate concern that economic pressure, social disconnection, unstable relationships or pessimism are making marriage and parenthood feel unattainable even to people who might ultimately want them.

Both possibilities can be true at the same time. A sensible public conversation should respect adults who choose a different path while also recognizing that helping people form the families they say they want is a worthwhile social goal.

The country will not know what today’s teenagers decide for many years. But the expectations they are forming now may be an early signal of what the American family looks like in the 2030s and 2040s.
