Key Takeaways
- Monaco has the world’s highest life expectancy today at 86.7 years and is projected to remain No. 1 through 2100.
- By the end of the century, the top-ranked countries are projected to have life expectancies approaching 95 years.
- Although U.S. life expectancy is expected to rise by nearly a decade, its global ranking is projected to fall from 45th to 48th.
Today’s longevity leaders are expected to remain near the top through the end of the century, even as average lifespans continue to rise.
Using projections from the UN’s World Population Prospects 2024 via Our World in Data, this ranking compares projected life expectancy in 2026 with projections for 2100.

Europe accounts for more than two-thirds of the world’s top 30 countries by life expectancy. It is also the continent with the highest median age.
Japan, South Korea, and Singapore also rank among the global leaders, showing that exceptional longevity is concentrated in a small number of regions.
What Changes by 2100?
Monaco is projected to remain in first place in 2100, when its life expectancy reaches 94.7 years. Japan rises to second at 94.4 years, overtaking San Marino.
Rather than a wholesale replacement of today’s leaders, the projections show a gradual reshuffling near the top. European countries continue to dominate the ranking, while Chile and Costa Rica enter the top 30 and stand out for their long lifespans relative to their income levels.

The U.S. illustrates how rising life expectancy does not necessarily translate into a higher global ranking. While Americans are projected to live nearly 10 years longer on average by 2100, several other countries are expected to improve even faster. As a result, the U.S. slips from 45th to 48th despite those gains.
