Declining Birth Rates, Childless Adults, and Population Growth
The landscape of parenthood in the United States is shifting, with more adults either planning to have fewer children or opting out of parenthood altogether. Two Pew Research Center studies shed light on these trends, exploring the reasons behind these decisions and their broader implications.
Fewer Children, Changing Plans
A 2025 Pew analysis revealed that U.S. adults in their 20s and 30s are planning to have fewer children than previous generations. The average number of children these adults plan to have dropped from 2.3 in 2012 to 1.8 in 2023. The trend is consistent across genders and age groups, with the steepest declines among women aged 20 to 24.
Several factors contribute to this shift. Economic concerns, career aspirations, and societal changes play a role, as do broader discussions about low birth rates and potential policy interventions. For instance, many Americans believe that measures like free childcare and paid family leave could encourage higher birth rates.
The Experiences of Adults Without Children
A separate 2024 Pew report examines the experiences of U.S. adults without children, focusing on two groups: those aged 50 and older who never had children and those under 50 who are unlikely to have them. Among younger adults, the primary reason for not having children is simple—they just don’t want to. Other reasons include financial concerns, career priorities, and worries about the state of the world, including climate change.
Interestingly, many adults without children report benefits such as greater financial freedom, more time for hobbies, and career success. However, they also acknowledge potential challenges, particularly as they age, such as concerns about caregiving and loneliness.
A Broader Cultural Shift
These findings highlight a broader cultural shift in how Americans view parenthood. While the decision to have children remains deeply personal, it is increasingly influenced by economic, social, and environmental factors. Understanding these trends is crucial for shaping policies that support families and individuals alike.
Individual Choices and National Policies
The studies on declining birth rates and the experiences of childless adults in the U.S. align closely with the themes explored in NPG’s new Forum paper, Why ZPG Did Not Achieve Its Goal to Lower Population and Why We Can’t Grow On Forever. While Pew highlights the growing trend of adults planning to have fewer or no children, driven by personal, economic, and environmental concerns, NPG’s paper underscores that smaller family sizes alone have not curbed U.S. population growth. Both sources point to broader systemic factors—Pew through the lens of shifting societal priorities and NPG by emphasizing the role of immigration in sustaining population increases. Together, they paint a comprehensive picture of how individual choices and national policies intersect in shaping America’s demographic and environmental future.
