How the figure for Australia is worked out
The United Nations puts the population of Australia at 27,227,097 on 1 July 2026, and projects 27,474,269 for 1 July 2027. The counter above moves steadily between those two published points, which works out at about 0.01 people added every second.
That places Australia at number 55 of the 237 countries and areas the United Nations reports, holding 0.33 per cent of everyone alive, and among the largest of the 23 entries in Oceania.
Underneath that single number sit roughly 303,345 births and 187,031 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.
