Countries by Life Expectancy

What Life Expectancy Measures

Life Expectancy is a comparative indicator tracked across countries by the OECD. It provides a quantitative basis for cross-national comparison, enabling researchers and policymakers to benchmark national performance on this dimension against global peers.

Why This Ranking Matters

Examining Life Expectancy across all countries reveals patterns that might not be obvious at the national level. Regional clusters, outlier nations, and historical trajectories all become clearer when the full global picture is assembled in a single ranking.

Global Range

Values range from 75.5 (Mexico) to 84.3 (Switzerland) — minimal difference across 38 countries.

Regional Patterns

European countries dominate this ranking, holding 15 of the top 20 positions. This strong regional concentration suggests shared economic, geographic, or policy factors that drive higher values across the continent.

Values are broadly distributed across countries, with the middle 50% ranging from 79.1 to 83. The overall spread from 75.5 to 84.3 reflects significant global variation.

Notable Outliers

The top of the ranking is competitive: Switzerland and Japan are separated by only 0%, indicating that the leading positions could shift with updated data.
