The U.S. and other nations are grappling with declining birth rates, leading to significant demographic shifts. More individuals and couples are opting for smaller families or remaining childless, resulting in an aging population. This trend poses unprecedented challenges, potentially leading to workforce shortages, strain on social security systems, and overall economic instability as the population begins to shrink. The long-term implications of this demographic shift require careful consideration and proactive policy responses to mitigate potential negative consequences.
