Summer Friday: Birth Rates; Planet Money; Tech & Bodies; State of Marriage; Opera & Democracy

On this Summer Friday, we've put together some of our favorite recent interviews, including: The U.S. fertility rate dropped to another record low in 2025, according to provisional CDC data, marking a 23% drop since 2007. Jill Filipovic, attorney and author of several books, including OK Boomer, Let's Talk: How My Generation Got Left Behind (Atria/One Signal Publishers, 2020),  and Karen Guzzo, director of the Carolina Population Center and a sociology professor at the University of North Carolina at Chapel Hill, explain what's behind the decline, the current Republican and far-right conservative policy plans to try and reverse those trends and what actually works to incentivize a growing population. Alex Mayyasi, a longtime contributor to Planet Money and the author of Planet Money: A Guide to the Economic Forces That Shape Your Life (W. W. Norton & Company, 2026), and Mary Childs, a co-host of NPR's Planet Money, offers insight into making decisions on getting and spending money and why markets work the way they do. Manoush Zomorodi, host of NPR's TED Radio Hour and author of Body Electric: The Hidden Health Costs of the Digital Age and New Science to Reclaim Your Well-Being (Flatiron, 2026), talks about the impact on our bodies of our interactions with our phones and other tech -- and how to stay healthy and stay connected. Stephanie Coontz, director of research and public education at the Council on Contemporary Families and the author of The Way We Never Were; Marriage, a History; and now, For Better and Worse: The Complicated Past and Challenging Future of Marriage (Viking, May 26, 2026), offers historical context for the institution of marriage and examines the attitudes and policies that can strengthen it. Martha Nussbaum, professor of law and ethics at the University of Chicago and the author of The Republic of Love: Opera & Political Freedom (Oxford University Press, 2026), offers her analysis of opera as an arm of the Enlightenment, from Mozart to today.   These interviews were lightly polished up and edited for time, the original versions are available here: Why U.S. Birth Rates Are Dropping Planet Money: The Book Our Bodies & Our Tech Marriage in Context Opera and Democracy   Photo: Labor Day weekend crowds at Rockaway Beach, Queens, New York, September 2020.
