Life expectancy by country
Why country-level averages matter
When people search for life expectancy by country, they are usually trying to compare national baselines. Those baselines help explain why the same birth year and sex can lead to different estimates in different places.
- Healthcare systems vary.
- Nutrition and living conditions differ widely.
- Injury rates, violence, and road safety also matter.
- Average lifespan trends change over time.
A country calculator is useful because it gives context. It does not say what will happen to you personally, but it does anchor your estimate to a real population benchmark.
Life expectancy at birth by country (2023)
These figures show how long a newborn would live on average if the age- and sex-specific death rates observed in 2023 stayed constant throughout their life. They are population-level period estimates, not predictions for a person born in a particular year.

Source: World Bank, World Development Indicators — female and male life expectancy at birth indicators. Data year: 2023. Values are rounded to one decimal. The World Bank API provides these indicators by country and year.
How to read this comparison
The table ranks the countries supported by the calculator. Select a column heading to sort by country, female life expectancy, male life expectancy, or the difference between those two estimates. The difference is calculated from the rounded values shown in the table.
These are period estimates: they summarize the age-specific mortality rates recorded for a population in one year. They do not say how long a child born in 2023 will live, and the gap between female and male averages is not a measure of the effect of sex alone. Countries also differ in data collection, population composition, and the conditions that shape mortality.
Use the table to compare national context, not to rank individual health or predict what would happen if a person moved. The World Bank series is internationally comparable, but it is an estimate and may differ from a country's national statistics because methods and source data can differ.
Data and method
The figures come from the World Bank's World Development Indicators for 2023: SP.DYN.LE00.FE.IN for female and SP.DYN.LE00.MA.IN for male life expectancy at birth. Each row appears only when both sex-specific observations are available for the selected country and year. Values are shown to one decimal place. The difference column subtracts the displayed male value from the displayed female value.
The World Bank defines life expectancy at birth as the years a newborn would live if the mortality patterns at birth remained the same throughout life. The source draws on the UN World Population Prospects and national statistical sources. Data are requested from the public World Bank API when this page loads; if that request fails, use the source links to view the series directly.
Quick answers
What does life expectancy by country mean?
It is a summary of the mortality rates observed in a population during a particular year. At birth, it describes a hypothetical newborn exposed to those rates at every age.
Can I compare life expectancy countries directly?
Yes, if you keep the year and measure consistent. These figures compare life expectancy at birth, not remaining years for adults.
Does a higher country average guarantee I will live longer there?
No. It only signals a broader national average, not your personal outcome.
