Mapped: Life Expectancy Around the World in 2025
Introduction
How long can you expect to live? It depends a lot on where you’re born. A new global‐map snapshot for 2025 shows just how wide the variations in life expectancy still are, and what the driving forces behind those differences may be. Let’s explore what the data say — and what they might mean for you.
What do we mean by “life expectancy”?
“Life expectancy at birth” is the average number of years a newborn baby would live if current age‑specific mortality rates remained unchanged for their entire life. So it’s not a guarantee for any individual, but a useful statistical indicator of overall health and mortality patterns.

Key global figures for 2025
The global average life expectancy is estimated at approximately 73.5 years in 2025.

But this hides huge variation: in the top‐ranking countries, life expectancy surpasses 85 years, while in the lowest ranked countries it can be below 60 years.

Life expectancy by region: extremes and patterns
Best performers
Some of the highest life expectancies in 2025 are found in small and wealthy nations and certain developed economies:
Monaco – ~86.5 years (both sexes) in 2025.

San Marino, Hong Kong, Japan, South Korea also feature in the top ranks with ~84‑86 years.

Lowest performers
By contrast, some countries – especially in Sub‑Saharan Africa – have life expectancies below 60 years:
Chad, Nigeria among those with the lowest averages.

Geographic patterns
Developed countries in Europe, East Asia, Oceania tend to have life expectancies above ~80 years.

Many developing countries in Africa, parts of Asia lag behind, owing to factors such as higher rates of infectious disease, lower healthcare access, nutrition and sanitation challenges.

What drives these differences?
Several factors influence how long populations live. Some of the major ones:
Healthcare access and quality: Better medical services for birth, childhood, chronic diseases etc. significantly raise life expectancy.
Nutrition and sanitation: Clean water, good food, fewer infectious diseases reduce early mortality.
Economic wealth and infrastructure: Richer countries are generally able to invest more in public health, social safety nets, healthy environments.
Lifestyle and non‑communicable diseases: As mortality from infections drops, longer lives often mean more exposure to conditions like heart disease, cancer, diabetes. This alters the challenge: not just living longer but living healthier.

Child and maternal mortality: High mortality among newborns or infants drags down average life expectancy for entire populations.
Conflict, trauma, epidemics: Wars, disasters, pandemics can reverse or slow gains.
Why is 2025 interesting?
The data reflect post‑pandemic recovery in many regions: after dips due to COVID‑19, many countries’ life expectancies are rebounding.
The 2025 map also highlights persistent inequality: even though global average improves, the gap between highest and lowest remains large.
It provides a visual benchmark for policymakers, health organisations and the public to track progress not just in years lived, but years lived well.
What this means for people
If you were born in one of the high‑life‑expectancy countries, your chances of living into your mid‑80s are quite strong (assuming current trends hold).
If you’re in a country with <60 years average, your risk of earlier mortality (for factors beyond lifestyle alone) is still much higher.
Even in high‑expectancy nations, living longer raises new challenges: retirement, healthcare costs, quality of life in older age.
For developing regions, focusing on early‑life health (birth/infant care), infectious disease control, and basic infrastructure gains can yield large improvements.
For everyone, improving lifestyle (diet, exercise, stress reduction) matters — living longer is good, but living healthier matters too.
Limitations & things to note
These figures are projections and are subject to revision as new data come in. For many countries 2025 figures are estimated based on earlier trends.

Life expectancy at birth is a snapshot assuming current mortality rates hold — in reality, mortality rates can change.
“Average life expectancy” doesn’t reflect variation among individuals: within any country, factors like income, education, location, ethnicity will lead to big differences.
“Healthy life expectancy” (years lived in good health) is a different and increasingly important metric — living longer does not always mean living healthier

Final thoughts
The 2025 world life‑expectancy map is both good news and a reminder of unfinished work. On one hand, human beings globally are living longer than ever in history. On the other, where you are born still plays a massive role in how many years you might have.
If you run a blog, you could use this map to spark reflection: what can your country / region do to push life expectancy higher? What are the lifestyle take‑aways for your readers? Perhaps most importantly: not only to live longer, but to live better.
