Monaco had the highest life expectancy among both men and women worldwide as of 2024. That year, life expectancy for men and women was 84 and 89 years, respectively. The East Asian countries and regions Hong Kong, Japan, South Korea, and Macao followed. Many of the countries on the list are struggling with aging populations and a declining workforce as more people enter retirement age compared to people entering employment.

As of 2022, the countries with the highest life expectancy included Liechtenstein, Japan, and Switzerland. In Japan, a person could expect to live up to around 84 years. In general, the life expectancy for females is higher than that of males, with lifestyle choices and genetics the two major determining factors of life expectancy. Life expectancy worldwide The overall life expectancy worldwide has increased since the development of modern medicine and technology. In 2011, the global life expectancy was 70.53 years. By 2019, it had increased to 72.79 years. However, the years 2020 and 2021 saw a decline in global life expectancy due to the COVID-19 pandemic. Furthermore, not every country has seen a substantial increase in life expectancy. In Chad, for example, the life expectancy is only 53 years, almost 20 years shorter than the global average. In addition to Chad, the countries with the shortest life expectancy include Lesotho, Nigeria, and the Central African Republic. Life expectancy in the U.S. In the United States, life expectancy at birth is currently 77.43 years. Life expectancy in the U.S. generally increases every year, however, over the past decade, life expectancy has seen some surprising decreases. The major contributing factors to this drop have been the ongoing opioid epidemic, which claimed around 81,806 lives in 2022 alone, and the COVID-19 pandemic.

As of 2023, the countries with the highest life expectancy included Switzerland, Japan, and Spain. As of that time, a new-born child in Switzerland could expect to live an average of 84.2 years. Around the world, females consistently have a higher average life expectancy than males, with females in Europe expected to live an average of six years longer than males on this continent. Increases in life expectancy The overall average life expectancy in OECD countries increased by 11.3 years from 1970 to 2019. The countries that saw the largest increases included Turkey, India, and South Korea. The life expectancy at birth in Turkey increased an astonishing 24.4 years over this period. The countries with the lowest life expectancy worldwide as of 2022 were Chad, Lesotho, and Nigeria, where a newborn could be expected to live an average of 53 years. Life expectancy in the U.S. The life expectancy in the United States was 77.43 years as of 2022. Shockingly, the life expectancy in the United States has decreased in recent years, while it continues to increase in other similarly developed countries. The COVID-19 pandemic and increasing rates of suicide and drug overdose deaths from the opioid epidemic have been cited as reasons for this decrease.

The countries with the lowest life expectancy worldwide include the Chad, Lesotho, and Nigeria. As of 2022, people born in Chad could be expected to live only up to 53 years. This is almost 20 years shorter than the global life expectancy. Life expectancy The global life expectancy has gradually increased over the past couple decades, rising from 70.53 years in 2011 to 72.79 years in 2019. However, the years 2020 and 2021 saw a decrease in global life expectancy due to the COVID-19 pandemic. Furthermore, life expectancy can vary greatly depending on the country and region. For example, all the top 20 countries with the lowest life expectancy worldwide are in Africa. The countries with the highest life expectancy include Liechtenstein, Japan, and Switzerland. Causes of death The countries with the lowest life expectancy worldwide are all low-income or developing countries that lack health care access and treatment that more developed countries can provide. The leading causes of death in these countries therefore differ from those of middle-income and upper-income countries. The leading causes of death in low-income countries include diseases such as HIV/AIDS and malaria, as well as preterm birth complications, which do not cause substantial death in higher income countries.

This statistic shows the countries and territories with the highest projected life expectancy between 2050 and 2055. Between 2050 and 2055, Hong Kong SAR is projected to have a life expectancy at birth of 89.22 years.

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.

Over the past 160 years, life expectancy (from birth) in the United States has risen from 39.4 years in 1860, to 78.9 years in 2020. One of the major reasons for the overall increase of life expectancy in the last two centuries is the fact that the infant and child mortality rates have decreased by so much during this time. Medical advancements, fewer wars and improved living standards also mean that people are living longer than they did in previous centuries.

Despite this overall increase, the life expectancy dropped three times since 1860; from 1865 to 1870 during the American Civil War, from 1915 to 1920 during the First World War and following Spanish Flu epidemic, and it has dropped again between 2015 and now. The reason for the most recent drop in life expectancy is not a result of any specific event, but has been attributed to negative societal trends, such as unbalanced diets and sedentary lifestyles, high medical costs, and increasing rates of suicide and drug use.

Global life expactancy at birth has risen significantly since the mid-1900s, from roughly 46 years in 1950 to 73.5 years in 2025. Post-COVID-19 projections There was a drop of 1.7 years during the COVID-19 pandemic, between 2019 and 2021, however figures resumed upon their previous trajectory the following year due to the implementation of vaccination campaigns and the lower severity of later strains of the virus. By the end of the century it is believed that global life expectancy from birth will reach 82 years, although growth will slow in the coming decades as many of the more-populous Asian countries reach demographic maturity. However, there is still expected to be a wide gap between various regions at the end of the 2100s, with the Europe and North America expected to have life expectancies around 90 years, whereas Sub-Saharan Africa is predicted to be in the low-70s. The Great Leap Forward While a decrease of one year during the COVID-19 pandemic may appear insignificant, this is the largest decline in life expectancy since the "Great Leap Forward" in China in 1958, which caused global life expectancy to fall by almost four years between by 1960. The "Great Leap Forward" was a series of modernizing reforms, which sought to rapidly transition China's agrarian economy into an industrial economy, but mismanagement led to tens of millions of deaths through famine and disease.

This statistic shows the top ten countries worldwide with longest average female life expectancy at birth in 2010 and 2030. South Korea had the longest average life expectancy for females in 2030 at 90.82 years.

This statistic represents a ranking of the 20 countries with the highest life expectancy for people born in 2009. People who were born in Spain in 2009, at that moment had a life expectancy of approximately 81.5 years.

This statistic shows the average life expectancy in North America for those born in 2022, by gender and region. In Canada, the average life expectancy was 80 years for males and 84 years for females.

Life expectancy in North America

Of those considered in this statistic, the life expectancy of female Canadian infants born in 2021 was the longest, at 84 years. Female infants born in America that year had a similarly high life expectancy of 81 years. Male infants, meanwhile, had lower life expectancies of 80 years (Canada) and 76 years (USA).

Compare this to the worldwide life expectancy for babies born in 2021: 75 years for women and 71 years for men. Of continents worldwide, North America ranks equal first in terms of life expectancy of (77 years for men and 81 years for women). Life expectancy is lowest in Africa at just 63 years and 66 years for males and females respectively. Japan is the country with the highest life expectancy worldwide for babies born in 2020.

Life expectancy is calculated according to current mortality rates of the population in question. Global variations in life expectancy are caused by differences in medical care, public health and diet, and reflect global inequalities in economic circumstances. Africa’s low life expectancy, for example, can be attributed in part to the AIDS epidemic. In 2019, around 72,000 people died of AIDS in South Africa, the largest amount worldwide. Nigeria, Tanzania and India were also high on the list of countries ranked by AIDS deaths that year. Likewise, Africa has by far the highest rate of mortality by communicable disease (i.e. AIDS, neglected tropics diseases, malaria and tuberculosis).

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.

Men born in Chad have the lowest life expectancy in the world as of 2024, reaching only 53 years. The lowest life expectancy for women in the world in 2024 was for girls born in Nigeria, with only 55 years. Except for Afghanistan, all the countries with the lowest life expectancy in the world are in Africa.

Singapore had the highest life expectancy at birth of all the Southeast Asian countries in 2023, with its citizens expected to live to an average of 84.3 years. Falling behind by almost 20 years was Myanmar, with a life expectancy of 67.5 years old at birth as of 2023. Interestingly, Singapore made the top ten of countries with the highest average life expectancy worldwide. Increasing life expectancyLife expectancy throughout the Southeast Asian region has been rising throughout recent years, likely due to improved healthcare systems. Improvements brought about by increasing healthcare expenditures. The East Asian region also joined Southeast Asia in displaying higher life expectancies at birth, with Hong Kong and Macao all exhibiting life expectancies at birth of over 85 years old. Improved healthcare Thailand, the Philippines and Singapore are just some of the Southeast Asian governments which have released successful universal healthcare plans. As the region faces an aging population, there has been more demand for effective healthcare. Healthcare has been improving not just in the Southeast Asian region but throughout the whole Asia Pacific region, with many countries exhibiting near perfect child immunization rates, offering its citizens better healthcare from birth. With these improvements made, it does not seem surprising that life expectancy at birth has increased.

Algeria had the highest life expectancy at birth in Africa as of 2023. A newborn infant was expected to live over 77 years in the country. Cabo Verde, Tunisia, and Mauritius followed, with a life expectancy between 77 and 75 years. On the other hand, Chad registered the lowest average, at nearly 54 years. Overall, the life expectancy in Africa was almost 63 years in the same year.

This statistic shows the average life expectancy in Europe for those born in 2024, by gender and region. The average life expectancy in Western Europe was 79 years for males and 84 years for females in 2024. Additional information on European life expectancy The difference in life expectancy seen between men and women across all European regions is in line with the global trends of women outliving men, on average. The average life expectancy at birth worldwide by income group shows that the gender life expectancy gap is not only a consistent trend across countries, but also income groups. Moreover, the higher life expectancy for those in high income groups may help to explain the lower average life expectancy for those born in Eastern Europe where average incomes are generally lower than other European regions. Although income and length of life are not directly correlated, higher income individuals are generally able to afford access to superior nutrition and healthcare as well as having leisure time for exercise. That said, current trends in the increases in life expectancy worldwide by country between 1970 and 2017 suggest economic growth will lead to larger increases in life expectancy. Those increases are less likely to occur to such a degree in the more developed regions of Europe where Italy, Spain, France, Switzerland, Iceland and Austria all rank in the top 20 countries with the highest life expectancy.

A global phenomenon, known as the demographic transition, has seen life expectancy from birth increase rapidly over the past two centuries. In pre-industrial societies, the average life expectancy was around 24 years, and it is believed that this was the case throughout most of history, and in all regions. The demographic transition then began in the industrial societies of Europe, North America, and the West Pacific around the turn of the 19th century, and life expectancy rose accordingly. Latin America was the next region to follow, before Africa and most Asian populations saw their life expectancy rise throughout the 20th century.

Japan had the highest life expectancy at birth of the G7 countries between 2000 and 2024, reaching 84.9. On the other hand, life expectancy in the United States was 79.5 years, the only one of the seven where it was below 80. Life expectancy dropped in all G7 countries following the COVID-19 pandemic.

Sunshine, Mediterranean diet, and a sociable lifestyle must be the secret to living a long life, because Spain’s life expectancy ranked as one of the highest on the planet according to the most recent studies. The Mediterranean country managed to increase its average life expectancy by approximately two years in the last decade, standing at 83.77 years old as of 2023. Regions full of life: developed Asia and the Latin Arch There seems to be a pattern as to where in the world people’s lives tend to be longer. As can be seen in the most recent data, Japan topped the list of the countries with the longest life expectancy at 84 years old. Other developed Asian countries can be found on this list, Republic of Korea with a life expectancy of approximately 83 years old and Singapore with 83 years old. Similarly, along with Spain, France, and Italy both featured a very high life expectancy. The latest studies show that people that were born in these Mediterranean countries had an expected life length of roughly 83 years at birth. Ageing: a common problem across the continent Data related to age in Spain essentially behave in a similar fashion as the rest of its European counterparts, whose population is also slowly but surely getting older. This will not come as a surprise since Spain has one of the highest life expectancies at birth in the world and one of the lowest European fertility rate, which stood at 1.29 children per woman according to the latest reports.

In 2022, people who identified as Asian had a projected life expectancy of 84.5 years, the highest in the United States, whereas an American Indian or Alaska native had the lowest with 67.9 years. From 2019 to 2021, life expectancy at birth declined in the U.S., regardless of race and ethnicity. One of the main drivers of this decline was the COVID-19 pandemic.
