Global life expectancy from 1960 to 2100: A United Nations perspective

Global life expectancy has changed remarkably over the past six decades, and projections indicate that it will continue to evolve through the end of the 21st century.

The United Nations World Population Prospects provides a comprehensive analysis of these trends, offering insights into the factors driving changes in life expectancy and what the future might hold.

From 1960 to 2020, global life expectancy at birth increased significantly. In 1960, the average life expectancy was around 50.09 years. Substantial healthcare, nutrition, and sanitation improvements contributed to this steady rise. By 2020, the global average had risen to approximately 72.6 years.

Looking ahead, the United Nations projects that global life expectancy will continue to rise, albeit slower. By 2050, the global average is expected to reach around 77.1 years; by 2100, it could be as high as 81.88 years. These projections are based on continued advancements in medical technology, improved healthcare access, and better living conditions worldwide.

However, life expectancy trends have varied widely across regions. Developed regions, such as North America and Europe, experienced earlier and more rapid increases in life expectancy due to advanced healthcare systems and higher living standards. In contrast, developing regions, particularly in Sub-Saharan Africa, faced challenges such as infectious diseases and limited healthcare access, which slowed progress.
