Disclaimer: Illustrative real-time extrapolation from the latest annual UN / World Bank rates — not an official live birth or death registry. Actual vital events vary by hour, season, and country; migration is reflected only via the published population growth rate.

Method: Population compounds from the mid-year World aggregate using the latest annual growth rate. Births and deaths apply crude birth and death rates (per 1,000 people) to the live population estimate, then prorate by elapsed fraction of the day or calendar year.
