How the figure for Cook Islands is worked out
The United Nations puts the population of Cook Islands at 12,851 on 1 July 2026, and projects 12,461 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 Cook Islands at number 226 of the 237 countries and areas the United Nations reports, holding 0.00 per cent of everyone alive, and somewhere in the middle of the 23 entries in Oceania.
Underneath that single number sit roughly 133 births and 128 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.
