How the figure for United States is worked out
The United Nations puts the population of United States at 349,035,484 on 1 July 2026, and projects 350,728,354 for 1 July 2027. The counter above moves steadily between those two published points, which works out at about 0.05 people added every second.
That places United States number 3 of the 237 countries and areas the United Nations reports, holding 4.20 per cent of everyone alive, and among the largest of the 41 entries in North America.
Underneath that single number sit roughly 3,673,260 births and 3,136,204 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.
