Elon Musk has never been one to shy away from controversial statements. One of his most consistent warnings in recent years has been a warning about the collapse of global birth rates. Recently, he posted a striking map of fertility data from around the world, underscoring what demographers and economists increasingly recognize: the problem facing humanity is not overpopulation but rather underpopulation.
This stands in stark contrast to the narrative that dominated the last half of the 20th century. In 1968, Paul Ehrlich’s book The Population Bomb became a bestseller. It predicted catastrophic famine, resource depletion, and societal collapse due to runaway population growth. These dire prophecies shaped policy and culture for decades, inspiring everything from aggressive sterilization campaigns to China’s infamous “one-child policy.” Yet today, Ehrlich’s predictions have been concisely expunged by reality. Far from facing a population explosion, the world is heading toward population decline.
A Global Fertility Collapse
Data from the United Nations and national governments confirm what Musk has been saying: birth rates are falling everywhere. In most Western countries, to sustain a stable population, the country must average about 2.1 children per woman—the so-called “replacement rate.” But many nations are well below this threshold. Japan’s fertility rate hovers around 1.3, prompting fears of a “demographic time bomb.”

Germany and much of Western Europe struggle with similar numbers, while Eastern European countries like Lithuania face even sharper declines. China, long enforcing its one-child policy with brutal efficiency, has now abandoned it entirely and is scrambling to encourage families to have more children. Russia, in a dramatic move, has offered citizens the equivalent of $7,600 for each newborn child.
In 2022, birth rates in the United States hit a record low. Experts argue that for long-term economic stability, the United States needs about 2.2 children per household, but the reality is closer to 1.6. In 2020, about half of U.S. states recorded more deaths than births—a sobering statistic signaling that the problem is not distant but already present.
Musk has warned repeatedly: “If people don’t have more children, civilization is going to crumble. Mark my words.” His stark prediction reflects not only economic realities—fewer workers supporting more retirees, declining innovation, and shrinking consumer bases—but also cultural and spiritual ones.
The Church’s Balanced Voice
The Catholic Church—often accused of clinging to “archaic” teachings about family and sexuality—provides a uniquely balanced response to the crisis. Contrary to caricatures, the Church has never commanded families to have “as many children as humanly possible.” Instead, she teaches openness to life—an openness rooted in love, trust, and cooperation with God’s plan.
St. John Paul II, in his Letter to Families (1994), reminded the world that demographic trends reflect more than economics: “The future of humanity passes by way of the family. It is therefore indispensable and urgent that everyone…strive to ensure that the institution of the family be safeguarded and promoted.”
In other words, falling birth rates are not simply about fewer workers in the labor force. They reveal a crisis of hope, of love, of culture. Children are not seen as blessings but as burdens. Families are delayed or foregone entirely for fear of inconvenience, expense, or loss of personal freedom.
Saints and the Call to Life
The saints have long testified to the joy and fruitfulness of openness to life. St. Catherine of Siena, a spiritual mother though not a biological one, famously said: “Be who God meant you to be and you will set the world on fire.”
For most married couples, this vocation includes raising children—not as a lifestyle choice but as a participation in God’s creative love. Similarly, the late Pope Francis criticized what he calls the “demographic winter” afflicting many nations, lamenting societies that “close the doors to life” and equating them to places that are “devoid of hope.”
Pope Benedict XVI also linked this demographic decline to deeper cultural currents, noting: “The true answer to the decline in births lies in a renewed appreciation of the family and of the meaning of life” (Address to Italian Mayors, 2006).
The Path Forward
While governments scramble to offer subsidies and incentives for more births, the Catholic Church reminds us that the problem is not only financial but spiritual. People will not embrace large families—or even modestly sized ones—if they lack a vision of life as a gift and a mission. What is needed is not merely tax credits but a cultural renewal that celebrates family life, sees children as blessings rather than liabilities, and trusts in God’s providence.
Elon Musk may not share the Church’s theological foundations, but his warnings point toward the same reality. A civilization that stops having children has chosen against its own future. In the words of St. John Paul II: “A society will be judged on the basis of how it treats its weakest members; and among the most vulnerable are surely the unborn and the children who are the hope of the future.”The fertility crisis is not only an economic issue but a moral and spiritual one. And here, as so often, the Catholic Church’s perennial wisdom proves both timely and timeless: be open to life, trust in God, and rediscover the joy of the family.
