what is the life expectancy
Life expectancy is the average number of years a person is expected to live, based on current death rates for people of different ages in a given place and time.
What “life expectancy” means
- Life expectancy is a statistical estimate of how long people are likely to live if today’s age-specific death rates stay the same throughout their lives.
- It is not a guarantee for any individual person; instead, it describes the overall mortality pattern in a population.
Common types (like “at birth”)
- The most common measure is life expectancy at birth , which is the average number of years a newborn is expected to live under current mortality conditions.
- Life expectancy can also be calculated at other ages (for example, “at age 65”), meaning the additional years someone of that age can expect to live if current age-specific death rates continue.
Typical recent numbers
- Globally, life expectancy rose from about 66.8 years in 2000 to around 73.1 years in 2019, before falling back several years because of the COVID‑19 pandemic.
- In the European Union, recent estimates put life expectancy at birth at about 81.7 years in 2024, with higher values in countries like Italy, Sweden, and Spain, and lower values in countries such as Bulgaria and Romania.
Why life expectancy varies
- Life expectancy differs by country, sex, socioeconomic status, race/ethnicity, and access to healthcare, so figures are usually given for specific groups rather than for everyone combined.
- Factors influencing it include medical care, nutrition, lifestyle (such as smoking or exercise), environment, and broader social and economic conditions.
