Global Demographic Changes: Older Adults Surpassing Young Children

The global population dynamic has significantly shifted in 2023, marking the first instance where people aged 65 and older outnumbered children aged 5 and under. This shift, highlighted in a new U.S. Census Bureau report, arrived sooner than predicted. Falling birth rates combined with longer life expectancies have expedited this demographic transformation.

The change signals profound economic and social challenges. Shrinking workforces and rising dependency ratios concern governments worldwide. Nonetheless, this demographic shift also reflects a success story: increased life expectancy and better survival rates.

According to the report, in 2023, over 71% of the world’s population lived in countries with fertility rates at or below the replacement level of approximately 2.1 children per woman. This is a significant rise from 45% in 2013. Major population centers, including China and India, now report fertility rates below replacement levels. Countries like Bangladesh, Mexico, and Vietnam have also seen similar trends since 2013.

Life expectancy continues to increase. Projections indicate that the number of people aged 65 and older will rise from approximately 852 million in 2025 to nearly 2 billion by 2060. By then, nearly one-fifth of the global population will be older adults, compared to about one-tenth today.

This growing elderly demographic is expected to impact labor markets, healthcare systems, and pension programs. Fewer younger workers will be available to support the aging population, increasing stress on social welfare and long-term care services.

The report notes, “Countries are trying to address old age poverty with various social pension schemes, but the demand far outstrips supply.”

The report points out that despite advancements in infrastructure for older adults in high-income countries, informal caregiving, mostly by women, remains crucial. Even when older parents do not live with their children, proximity is common.

The COVID-19 pandemic made these challenges more acute. Older people faced job losses, reduced healthcare access, isolation due to limited digital connectivity, and adverse impacts from extreme temperatures.

Regional Analysis: Population Shifts

This demographic shift is not limited to Europe or North America. Asia will see the largest increase in its older population, projected to increase from 487 million in 2025 to 1.24 billion by 2060. Africa, the world’s youngest region, will also experience more than a fourfold increase in its elderly population during the same period.

The United States shares in this pattern. Predictions show that by 2025, 18.9% of the American population will be aged 65 and older, increasing to 23.4% by 2060. The overall U.S. population is expected to grow from 344 million in 2025 to 404 million by 2060.
