How the figure for South Korea is worked out
The United Nations puts the population of South Korea at 51,600,389 on 1 July 2026, and projects 51,518,848 for 1 July 2027. The counter above moves steadily between those two published points, which works out at about 0.00 people lost every second.
That places South Korea at number 31 of the 237 countries and areas the United Nations reports, holding 0.62 per cent of everyone alive, and somewhere in the middle of the 51 entries in Asia.
Underneath that single number sit roughly 249,556 births and 385,355 deaths a year. The gap between them is natural increase; the difference between natural increase and the change in total population is migration.
None of this is counted in real time. No country registers births and deaths as they happen and publishes them to the second. The seconds ticking above are arithmetic between two annual reference points, and the broad figure is far more reliable than its final digits.
