In 2023, the average life expectancy of the world was 70 years for men and 75 years for women. The lowest life expectancies were found in Africa, while Oceania and Europe had the highest.

What is life expectancy?

Life expectancy is defined as a statistical measure of how long a person may live, based on demographic factors such as gender, current age, and most importantly the year of their birth. The most commonly used measure of life expectancy is life expectancy at birth or at age zero. The calculation is based on the assumption that mortality rates at each age were to remain constant in the future.

Life expectancy has changed drastically over time, especially during the past 200 years. In the early 20th century, the average life expectancy at birth in the developed world stood at 31 years. It has grown to an average of 70 and 75 years for males and females respectively, and is expected to keep on growing with advances in medical treatment and living standard continuing.

Highest and lowest life expectancy worldwide

Life expectancy still varies greatly between different regions and countries of the world. The biggest impact on life expectancy is the quality of public health, medical care, and diet. As of 2021, the countries with the highest life expectancy were Japan, Liechtenstein, Switzerland, and South Korea, all at 84 years. Most of the countries with the lowest life expectancy are mostly African countries. The ranking was led by the Chad, Nigeria, and Lesotho with 53 years.

Life expectancy at birth and at age 65, by sex, on a three-year average basis.

This table contains the cohort survival tables (per 1-year birth cohort) by sex and age for the population of the Netherlands. The table shows how many boys or girls out of a group of 100,000 newborns have reached the year in which they become 1, 2, 3, etc. years old. It is also possible to see how old these children will be on average. The table can be broken down into mortality probability, the number of people alive (table population), the number of deaths (table population) and (cohort) life expectancy per generation by gender and age. The (cohort) life expectancy, calculated from a cohort survival table, indicates what the actual lifespan is (or is expected to be, when the observed mortality probabilities are supplemented with mortality probabilities from the forecast period). See section 4 for an explanation of the difference between the period survival table and a cohort survival table. A choice can be made from figures in which only observed numbers have been calculated, or a series in which the observed numbers have been supplemented with future expectations of the number of deaths for the birth generations that are still alive. Data available: from birth generation 1850 Status of the figures: The figures based on the numbers of deaths observed up to and including the year 2021 are final. Figures supplemented with future expectations of the number of deaths come from the CBS Core Forecast 2022-2070. This forecast is reviewed once a year. Changes as of 16 December 2022: - The figures relating to mortality observations for 2021 have been incorporated in the table; - The figures relating to the forecasts have been replaced by those from the Core Forecast 2022-2070. When will new numbers come out? In December 2023, the mortality observations for 2022 will be processed in this table and the future expectations will be replaced by those from the Population Forecast 2023-2070.

Life expectancy at birth is the average number of years a group of infants would live if they were to experience, throughout their lives, the age-specific death rates prevailing during a specified period. Life expectancy at birth estimates were calculated using abridged period life tables according to the Chiang method. Estimates are based on provisional data and subject to change. Unstable estimates are excluded and are defined as having confidence intervals greater than 6 years, i.e., +/-3.0 years. The average life expectancy of a population is one of the most basic and important measures of the health of a community. Life expectancy is heavily driven by the social determinants of health, including social, economic, and environmental conditions, with Black and low-income individuals experiencing much lower life expectancies compared to White and more affluent individuals.For more information about the Community Health Profiles Data Initiative, please see the initiative homepage.

Life expectancy is the average number of years of life left at a particular age, based on death rates for a given period. This is a hypothetical measure useful for tracking mortality trends in the population.

International estimates of mean life expectancy at age 40, by country for men and women

Dataset replaced by: http://data.europa.eu/euodp/data/dataset/tHJ7RfJO3ZAXvnwP5Jm5kw The indicator Healthy Life Years (HLY) at age 65 measures the number of years that a person at age 65 is still expected to live in a healthy condition. HLY is a health expectancy indicator which combines information on mortality and morbidity. The data required are the age-specific prevalence (proportions) of the population in healthy and unhealthy conditions and age-specific mortality information. A healthy condition is defined by the absence of limitations in functioning/disability. The indicator is calculated separately for males and females. The indicator is also called disability-free life expectancy (DFLE). Life expectancy at age 65 is defined as the mean number of years still to be lived by a person at age 65, if subjected throughout the rest of his or her life to the current mortality conditions.

In 2023, the average life expectancy for those born in more developed countries was 75 years for men and 82 years for women. On the other hand, the respective numbers for men and women born in the least developed countries were 63 and 67 years.

Improved health care has lead to higher life expectancy

Life expectancy is the measure of how long a person is expected to live. Life expectancy varies worldwide and involves many factors such as diet, gender, and environment. As medical care has improved over the years, life expectancy has increased worldwide. Introduction to health care such as vaccines has significantly improved the lives of millions of people worldwide. The average worldwide life expectancy at birth has steadily increased since 2007, but dropped during the COVID-19 pandemic in 2020 and 2021.

Life expectancy worldwide

More developed countries tend to have higher life expectancies, for a multitude of reasons. Health care infrastructure and quality of life tend to be higher in more developed countries, as is access to clean water and food. Africa was the continent that had the lowest life expectancy for both men and women in 2023, while Oceania had the highest for men and Europe and Oceania had the highest for women.

Life expectancy is the number of years a person would be expected to live, starting from birth (for life expectancy at birth) or at age 65 (for life expectancy at age 65), on the basis of the mortality statistics for a given observation period. Life expectancy is a widely used indicator of the health of a population. Life expectancy measures quantity rather than quality of life.
