According to Statistics Korea, life expectancy at birth - average projected lifespan - reached 82.7 years as of 2018.
South Korea posted the same life expectancy a year earlier, ranking quite high among 36 members of the Organisation for Economic Cooperation and Development.
Japan topped the list with 84.2 years, followed by Switzerland with 83.6, Spain with 83.4 and Italy with 83. South Korea, alongside Iceland and Norway, ranked fifth as of 2017.

After topping 85 in 2029, the figure would gradually climb to 86.8 in 2040, 88.2 in 2050, and 90 (88.4 for men and 91.6 for women) in 2066, the state-run agency noted.
Analysts warn that the social burden of caring for elderly people will worsen in the coming years and decades.
The Korea Economic Research Institute predicted that the nation will see its "gross domestic product drop by 0.97 per cent every time the proportion of elderly people to the total population increases by 1 percentage point".
From December 2009 to December 2019, the number of Koreans aged 80 or over increased by more than a million - from 876,000 (1.7 per cent of then population) to 1.88 million (3.6 per cent of the current population), according to the Ministry of Interior and Safety.
As for all seniors - those aged 65 or over - the number came to 8.02 million as of December, compared to 5.26 million.
Data from the United Nations suggested that Koreans' lifespan increased sharply, at the highest speed in the world since 2000.
