The country with the longest life expectancy in the world is Monaco at 85.9 years

　　According to the interactive map released by the visual data website “Our World in Data” founded by Oxford University, among all countries and regions in the world, Monaco in Europe tops the list with 85.9 years old, and the African Republic of Chad The average life expectancy is the shortest, only 52.5 years. my country’s Hong Kong and Macau rank second and third, ahead of Japan.
　　Monaco is located in the south of France, facing the sea on one side and surrounded by France on three sides. It has a population of 40,000 and is the second smallest country in the world, second only to the Vatican. It’s a principality known for its wealth, even nicknamed “Billionaires’ Playground”. The latest data from “Our World in Data” shows that the average life expectancy of Monaco’s population is 85.9 years old, making it the country and region with the longest average life expectancy in the world.
　　The Republic of Chad, located between North and Central Africa, is at the bottom of the ranking with an average life expectancy of only 52.5 years. Chad is also one of the poorest countries in the world. It is worth noting that the 10 countries and regions with the shortest life expectancy are all in Africa. In addition to Chad, Nigeria, Lesotho, the Central African Republic, South Sudan, Somalia, Eswatini, Côte d’Ivoire, Guinea and Mali are all in Africa. Over 60 years old.

　　Health inequalities have also improved slightly. In 1950, the average life expectancy in the Republic of Mali in West Africa was only 28.2 years, while Norway had the highest life expectancy at 71.2 years, a difference of 43 years. In 2021, however, the gap between the countries with the highest life expectancy and the lowest has narrowed to 33.4 years. Of course, huge divides between countries remain. Canada and many Central and Nordic countries live to more than 80 years, while many African countries are still in their 50s.

　　It is understood that the “Our World in Data” interactive map uses the latest data from the United Nations Population Division, which tracks the development of populations in countries. After Monaco is my country’s Hong Kong region, with an average life expectancy of 85.5 years. The Macao region of my country ranks third, with an average life expectancy of 85.4 years. Japan only ranks fourth at 84.5 years old. The top ten countries and regions are Australia (84.5 years old), Switzerland (84 years old), Malta (83.8 years old), South Korea (83.7 years old), Liechtenstein (83.3 years old) and Norway (83.2 years old).
　　Neither the UK nor the US made it into the top 30. The UK is ranked 34th for life expectancy at 80.7 years. The average life expectancy in the United States is only 77.2 years, ranking 69th. Due to advances in medicine, the average life expectancy of the world’s population has increased substantially over the past few decades. In 1950, the average human life expectancy was 46.5 years, but by 2021 this number has soared to 71 years.
　　There has also been a slight improvement in health inequalities. In 1950, the average life expectancy in the Republic of Mali in West Africa was only 28.2 years, while Norway had the highest life expectancy at 71.2 years, a difference of 43 years. In 2021, however, the gap between the countries with the highest and lowest life expectancy narrowed to 33.4 years. Of course, huge divides between countries remain. Canada and many central and northern European countries live to more than 80 years, while many African countries are still in their 50s.
　　The growth rate of life expectancy in high-income countries has slowed in recent years, which experts say is linked to people approaching the maximum age limit for human survival and deaths from cardiovascular disease.
　　A study by researchers at the University of Oxford and the Max Planck Institute has shown that life expectancy has fallen in both top and bottom-ranked countries since the start of the pandemic due to an “unprecedented rise in death rates”. In 2019, the average life expectancy in Monaco was 86.5 years, which will drop to 85.9 years in 2021. Mali also dropped from 53.3 in 2019 to 52.5 in 2021.
