As of 2023, the countries with the highest life expectancy included Liechtenstein, Switzerland, and Japan. In Japan, a person could expect to live up to around ** 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 **** years. By 2023, it had increased to **** 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 Nigeria, for example, the life expectancy is only ** years, almost ***years shorter than the global average. In addition to Nigeria, the countries with the shortest life expectancy include Chad, Lesotho, and the Central African Republic. Life expectancy in the U.S. In the United States, life expectancy at birth is currently ***** 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 ****** 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 **** years. Around the world, females consistently have a higher average life expectancy than males, with females in Europe expected to live an average of *** years longer than males on this continent. Increases in life expectancy The overall average life expectancy in OECD countries increased by **** 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 ** years. Life expectancy in the U.S. The life expectancy in the United States was ***** years as of 2023. 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 average for 2022 based on 192 countries was 74.94 years. The highest value was in Macao: 87.98 years and the lowest value was in Nigeria: 53.97 years. The indicator is available from 1960 to 2022. Below is a chart for all countries where data are available.

Monaco had the highest life expectancy among both men and women worldwide as of 2024. That year, life expectancy for men and women was ** and ** 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.

Countries where people live for a long time, as a rule, provide their citizens with high-quality medical care and help them lead a healthy lifestyle. On the contrary, in countries with low life expectancy, there are usually economic difficulties, poverty and lack of access to health services.

The countries with the lowest life expectancy worldwide include the Nigeria, Chad, and Lesotho. As of 2023, people born in Nigeria could be expected to live only up to ** years. This is almost ** years shorter than the global life expectancy. Life expectancy The global life expectancy has gradually increased over the past couple decades, rising from **** years in 2011 to **** years in 2023. 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, Switzerland, and Japan. 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.

The average for 2023 based on 24 countries was 75.17 years. The highest value was in Bermuda: 82.31 years and the lowest value was in Haiti: 64.94 years. The indicator is available from 1960 to 2023. Below is a chart for all countries where data are available.

The average for 2023 based on 12 countries was 75.35 years. The highest value was in Chile: 81.17 years and the lowest value was in Bolivia: 68.58 years. The indicator is available from 1960 to 2023. Below is a chart for all countries where data are available.

In 2024, the average life expectancy in the world was 71 years for men and 76 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 standards 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 2022, the countries with the highest life expectancy were Japan, Liechtenstein, Switzerland, and Australia, all at 84–83 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 53–54 years.

The average for 2023 based on 19 countries was 78.09 years. The highest value was in Japan: 84.04 years and the lowest value was in South Africa: 66.14 years. The indicator is available from 1960 to 2023. Below is a chart for all countries where data are available.

This statistic shows a ranking of 20 countries with the lowest life expectancy for people born in 2009. People who were born in Angola in 2009, at that moment had a life expectancy of 47.6 years.

The average for 2022 based on 7 countries was 81.52 years. The highest value was in Japan: 84 years and the lowest value was in the USA: 77.43 years. The indicator is available from 1960 to 2022. Below is a chart for all countries where data are available.

Tunisia had the highest projected life expectancy at birth in Africa as of 2025. A newborn infant was expected to live about 77 years in the country. Algeria, Cabo Verde, Morocco, and Mauritius followed, with a life expectancy between 77 and 75 years. On the other hand, Nigeria registered the lowest average, at 54.8 years. Overall, the life expectancy in Africa was just over 64 years in the same year.

The average for 2022 based on 47 countries was 77.29 years. The highest value was in Macao: 87.98 years and the lowest value was in Afghanistan: 66.21 years. The indicator is available from 1960 to 2022. Below is a chart for all countries where data are available.

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.

The ranking of countries by average age of the population shows at one end of the spectrum the countries with the highest average age of the population. At the other end are the countries with the youngest populations: they usually have high birth rates and not very long life expectancy.

Men born in Chad have the lowest life expectancy in the world as of 2024, reaching only ** years.

The first edition of the World Happiness Report was published on April 1, 2012 (omitted from this dataset), with a methodology that ranks countries based on their Happiness Index. Since its release, this report has garnered global recognition and has been issued on a yearly basis, excluding 2014.

Happiness Index is explained by: • Dystopia (adds 1.83 Index score) + residual • GDP per capita • Social support • Healthy life expectancy • Freedom to make life choices • Generosity • Perceptions of corruption.

Dataset provided in .xlsx and .csv formats. For convenience, dataset is provided with and without NULLs.

Possible use cases & questions: Initially the dataset was meant to be used for visualization practice with BI tools, for example, Tableau.

Clean dataset without nulls: 1) “Yearly average Happiness Index change” 2) “Are there countries who’s happiness was increasing for years, but had a sudden drop in recent years?” 3) “Is there a year(s) where the average world happiness decreased compared to last year?” 4) Geo data visualization.

With nulls: 1) Practice dealing with nulls. 2) “Which countries in which year had no ranking?” Deep dive and exploration into possible causes (for example, war, internal conflict, government or policy changes, diseases) via other sources.

Columns: Country – country name. Year – year of the report. Index – Happiness Index score. Rank – country rank according to their Happiness Index score.
