Average life expectancy will increase in many countries by 2030, according to new research.
Led by Imperial scientists in collaboration with the World Health Organization (WHO), the research shows that average life expectancy is expected to hit 90 in some developed countries by 2030.
Majid Ezzati, the lead researcher and a professor at Imperial College London’s school of public health said: “The fact that we will continue to live longer means we need to think about strengthening the health and social care systems to support an ageing population with multiple health needs.”
According to the study, published in The Lancet medical journal, South Koreans are likely to have the highest life expectancy in the world by 2030 while the United States is one of the lowest among developed countries.
Life expectancy is calculated by assessing the age at which people die across the whole population. A country where many young people die in injuries and violence will have a lower average national life expectancy, same thing as when there is a high childhood mortality rate.
As life expectancy increases globally, it is growing slowly in Nigeria and remains lower than many poorer countries in Africa.
Nigeria is ranked 216 in the world ranking of life expectancy and 16th in Africa with a life expectancy of 54.07 years. The average life expectancy in Nigeria 37 years ago was 44.74 years. In 2020, the average life expectancy in Nigeria is expected to rise to 55.23 years (ranking 214 globally and 14th in Africa), while in 2030, it will be 59.20 years (ranking 212) and by 2050, hit 68.15 (ranking 209 globally and 9th in Africa).
Below are 10 countries with the highest life expectancy by 2030.
1. South Korea
2. France
3. Japan
4. Switzerland
5. Australia
6. Canada
7. Gerrmany
8. United Kingdom
9. Singapore
10. United States
Top on the list for the 2030 life expectancy prediction is South Korea. A girl born in the country in 2030 should expect to live 90.8 years, while a boy could reach 84.1 years.
The United States is likely to have the lowest life expectancy in 2030, with men and women expecting to live 79.5 and 83.3 years respectively.
