Who are the "childfree"?
Most demographic research on reproduction just distinguishes between parents and non-parents. But, there are many types of non-parents:
childfree people do not want children
childless people want children but cannot have them
not-yet-parents plan to have children
undecided people have not decided if they will have children
ambivalent people have decided they will not have children, but aren't sure if they wanted children
Research on childfree people
One of the biggest challenges studying the childfree community is finding it. While most official data focuses on fertility, being childfree is more whether a person wants children, not whether they can have children. Most of our research has focused on ways to identify childfree adults through surveys, and to estimate their prevalence in the population. We estimate that one-in-five adults in Michigan (and possibly in the USA) are childfree. In addition, we've also found that most people who are childfree decided they did not want children early in life, typically in their teens or twenties, and that childfree people are less satisfied with their neighborhoods than parents.
This research on childfree adults has been widely covered by the media, including The Hill, National Public Radio, Daily Mail, Gizmodo, Men's Health, Der Standard, The Today Show, and The Young Turks. Kelly Ripa & Ryan Seacrest recently discussed it in their opening banter, and it was the focus of top r/science AMAs ("Ask Me Anything") on Reddit in 2021 and 2022. For a more extended discussion, you can list to Dr. Jennifer Watling Neal and I talk with Christine Erickson about this work on the New Legacy Institute podcast.
