A recent report from the Institute for Family Studies (IFS) highlights a notable difference in family size and parenting attitudes between liberals and conservatives in the United States. Based on a survey of over 7,000 Americans aged 18 to 54, the study reveals conservatives tend to have more children and desire larger families than their liberal counterparts. The findings also suggest liberals experience greater apprehension about parenting, genetics, and mental health, factors that may contribute to the ideological fertility gap.
Conservatives Have More Children and Larger Family Aspirations
The IFS report, titled “The Ideological Fertility Divide,” shows that conservative adults have an average of 1.40 children, while liberals average 1.09 children. This represents a 28% higher average number of children among conservatives. When asked about their ideal number of children, conservatives reported an average of 2.71, compared to 2.16 for liberals—approximately 25% higher.
These numbers reflect the surveyed age range of 18 to 54, which includes many younger adults who have yet to start families. The median age for marriage in the U.S. is now 30.8 for men and 28.4 for women, indicating a cultural trend toward later family formation. This context helps explain why the average number of children reported might seem low overall.
Parenting Fears More Common Among Liberals
One key factor behind the fertility divide is differing attitudes toward parenting. The survey found that 36% of liberals view parenting as “very complicated, difficult, and stressful,” compared to 24% of conservatives. Additionally, 18% of liberals were unsure if they would be good parents, double the 9% of conservatives who expressed uncertainty.
Concerns about passing on hereditary conditions were more prevalent among liberals (18%) than conservatives (10%). Mental health also played a role: 19% of liberals said their current mental health status was too poor to have children, compared to 10% of conservatives. These worries correlate with having fewer children and may partly explain the ideological differences in fertility.
Cultural Influences Shape Family Decisions
The report suggests that cultural factors, rather than strictly political ones, underpin the fertility gap. Theologian Carl Trueman’s concept of “expressive individualism”—the idea that personal authenticity and self-expression define identity—has a significant impact. This cultural mindset encourages prioritizing personal dreams and experiences, which can delay or reduce childbearing.
Expressive individualism is more influential among liberals, whose worldview aligns with these ideas. Conservatives, often grounded in Christian beliefs, tend to resist this cultural trend more consciously, which may contribute to their higher fertility rates.
The Role of Mental Health and Media
The study also highlights the influence of a “therapy culture” that emphasizes self-validation but may inadvertently weaken mental health. This effect appears stronger among liberals, potentially increasing their hesitancy toward parenting.
Moreover, American media and popular culture frequently portray negative or dismissive attitudes toward family life and parenting. Such portrayals can create distorted expectations, especially for young people who lack direct experience with family dynamics. This cultural environment may heighten fears about parenting adequacy across ideological lines.
Religious and Secular Perspectives on Family
Another cultural dimension involves differing views on human life and purpose. Secular perspectives, more common among liberals, may diminish the perceived importance of having children. Conversely, many conservatives embrace religious teachings that regard children as blessings and a vital part of life’s purpose.
Despite this, the average ideal family size among conservatives (2.71 children) remains modest and only slightly above replacement level. This suggests that even conservative family aspirations fall short of traditional religious ideals, which often encourage larger families.
Conclusion: A Spectrum of Family Values
The IFS report reveals meaningful but not extreme differences between liberals and conservatives regarding family size and parenting attitudes. While conservatives tend to have more children and express fewer parenting fears, the gap is one of degree rather than absolute divergence. Both groups navigate cultural influences that shape their views on family life, including individualism, mental health challenges, media portrayals, and underlying beliefs about human purpose.
Understanding these nuanced factors can foster a more informed conversation about family formation trends in America, beyond partisan stereotypes. As cultural dynamics continue to evolve, so too will the choices individuals make about parenting and family size.
