For the first time in recorded history, the number of people aged 65 and over has surpassed the number of children under five years old globally. This milestone, described as a "critical point" by experts, happened earlier than expected. According to a report by the United States Census Bureau titled An Aging World: 2025, released on August 31, the number of people aged 65 and above reached 852 million in 2023. This number is projected to grow to 2 billion by 2060, signaling a major shift in global demographics. The shift is largely due to declining birth rates around the world. Today, 71 percent of the global population lives in countries where the average number of children per woman has dropped below 2.1, the rate needed to maintain a stable population. This trend, once seen mainly in Europe and North America, is now widespread, affecting countries such as China, India, Bangladesh, Mexico, and Vietnam. While Africa remains the youngest continent, its aging population is expected to grow significantly, with the number of people aged 65 and over potentially quadrupling by 2060. This demographic shift is likely to have far-reaching effects on economies and societies. A smaller younger population could lead to fewer workers supporting a growing number of retirees, increasing pressure on pension systems and healthcare services. However, experts argue that an aging population is not inherently negative. It reflects improvements in healthcare and a reduction in infant and early mortality rates. Older adults tend to commit fewer crimes and often continue to participate in the workforce or volunteer, helping to address labor shortages in certain sectors. In the United States, the White House has become a focal point for discussions around encouraging higher birth rates. Meanwhile, countries in Asia are exploring ways to counteract declining birth rates. Singapore, for example, has seen the lowest number of births in sixty years, highlighting the challenges of reversing these demographic trends. The long-term implications of these shifts remain uncertain, but they are clearly reshaping the global landscape.
