How this number is worked out
This is an honest projection, not a live register. United States’s published annual figure is carried forward evenly over real elapsed time (peopleper second = the annual figure ÷ 31,556,952 seconds in a year). Each country’s NET population change so far — births and arrivals minus deaths and departures, projected from its annual growth rate. A few countries are shrinking; theirs counts down. The source is World Bank Open Data (CC-BY 4.0) (2024). The real total varies through the day and year; this is the running estimate, and we label it as one.
