Throughout history, demographic trends have shifted in ways that defy prediction. One such phenomenon is the decline in fertility rates, which serves as a powerful reminder that the current state is not the future state. Today, discussions around declining fertility often frame it as a looming crisis, raising fears of aging populations and economic stagnation. Yet, history provides a compelling counter-narrative. The reversal of fertility decline in the mid-20th century, driven by the baby boom, highlights the impossibility of predicting how societal, economic, and geopolitical forces will interact to shape our future.
