According to a large international study, by 2030, average life expectancy will rise in many countries. In some places, it will break through 90 years. Policymakers need to make more efforts to plan for it.

The study showed that by 2030, South Korea will likely to have the highest life expectancy in the world, while the United States one of the lowest among developed countries.

The lead researcher and a professor at Imperial College London’s school of public health, Majid Ezzati, said that “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,”

Life expectancy by country:

Imperial scientists led the study, in collaboration with the World Health Organization (WHO), they found that among high-income countries, the United States will probably have the lowest life expectancy in 2030.

American men’s life expectancy is 79.5 years while American women’s is 83.3 years. These ages are similar to middle-income countries such as Croatia and Mexico.

This is due to several factors, such as a lack of universal healthcare, relatively high child and maternal mortality rates, and high rates of homicides and obesity, according to the study.

In Europe, French women will average 88.6 years, and Swiss men nearly 84 years, making them the highest life expectancy.

Worldwide, South Korea topped all other countries. Researchers are predicting that a girl born in South Korea in 2030 would probably live up to live 90.8 years, while a boy could reach 84.1 years.

Their high average life expectancy is due to several factors including good childhood nutrition, low blood pressure, low levels of smoking and good access to healthcare, new medical knowledge and technologies

90 is not the upper limit:

Prof Ezzati said that many people used to believe that 90 years is the upper limit for life expectancy, but this research suggests we will break the 90-year-barrier.

“We repeatedly hear that improvements in human longevity are about to come to an end, but I don’t believe we’re anywhere near the upper limit of life expectancy, if there even is one,” he added.

The study covered 35 developed and emerging countries, including the United States, Canada, Britain, Germany, Australia, Poland, Mexico and the Czech Republic, it was published in The Lancet medical journal on Wednesday.
