(The Conversation) – Fears about declining fertility rates have come from sources as diverse as Pope Francis and Tesla CEO Elon Musk. The U.S. Supreme Court’s decision in Dobbs v. Jackson could force women to give birth against their wishes, while a recent British editorial even proposed a tax on people without children.
But how many Americans want to have kids and can’t? Or are still planning to be parents down the road? How many are consciously making the choice to never have kids?
While official statistics in the United States and elsewhere track fertility, they don’t provide insight into the people who have not had children. There are many different types of nonparents: “Childfree” people do not want children; “childless” people want children but can’t have them; “not-yet parents” plan to have children in the future; “undecided” people aren’t sure they will have children; and “ambivalent” people aren’t sure they would have wanted children.
Identifying childfree people
To identify childfree people, we asked each participant a series of up to three questions:
- Do you have, or have you ever had, any biological, step-, or adopted children?
- Do you plan to have any biological or adopted children in the future?
- Do you wish you had or could have biological or adopted children?
Respondents could answer “yes,” “no,” or “I don’t know” to each question. We classified as childfree those who answered “no” to all three.
Our estimate of the number of childfree people is much higher than past national studies, which placed the percentage between 2% and 9%. This likely happened because our measurement focuses on a person’s desire to have children, not their ability. This is important because a person can be childfree whether they are biologically capable of having children or not.
Our estimate is also slightly lower than an initial estimate – 27% – from a 2021 study that we wrote about a year ago. The original study did not allow respondents to answer “I don’t know” to these questions and therefore could not separate the undecided or ambivalent from the childfree. We were surprised that after refining our measurement to distinguish these unique groups, we still observed so many childfree adults.
Roughly half the adults in our study were parents, but childfree adults were the largest nonparent group. While our survey wasn’t nationally representative, the 2021 Census showed that Michigan is demographically similar to the United States in terms of age, race, education and income. If the pattern we have observed in Michigan reflects national trends, it would mean 50 million to 60 million American adults are childfree.
They’re deciding early in life
People, especially women, who say they don’t want children are often told they’ll change their mind. But we found that’s likely not the case.
In our study, people reported making the decision to be childfree early in life, most often in their teens and 20s. Moreover, it isn’t just young people who are claiming they don’t want children. Many women who decided in their teens to be childfree are much older now, and are still childfree.
Our findings depart from research conducted in the 1970s, which found that childfree adults tended to arrive at their decision later in life after postponing parenthood for many years. Earlier decisions may reflect changing norms toward parenthood and an increasing recognition and acceptance of a childfree lifestyle.
Underpopulation isn’t the problem
Despite Musk’s insistence that there is an underpopulation crisis, the global population will continue to grow.
Meanwhile, the Dobbs decision has chilling implications for the millions of Americans who are childfree: A significant swath of them are now at risk of being forced to have children despite not wanting them.

Issues affecting childfree Americans go beyond reproductive freedom. For example, workplace policies on work-life balance often favor parents. Because so many people are childfree, we believe the needs of this group warrant more attention from policymakers.
