How the daily number is calculated
Daily births are usually derived from annual estimates. If the world has roughly 130 million births in a year, dividing by 365 gives about 356,000 births per day. Rounding to 360,000 avoids false precision.
Why it is not a live count
No global system receives every birth in real time. International estimates combine national registrations, censuses, fertility rates and demographic models.
Why births are unevenly distributed
Births are concentrated where many people are of reproductive age and fertility is higher. A young age structure can keep the absolute number of births high even as fertility rates decline.
