How the estimate is produced
Mortality estimates come from civil registration, censuses, age structures, life tables and demographic models. A daily value is an average derived from annual or period estimates.
Why the number varies
Deaths vary by age, region, season, disease, conflict, health care and data quality. A global daily value should therefore be read as an order of magnitude.
Births, deaths and net growth
Population grows when births exceed deaths. With about 360,000 births and about 170,000 deaths per day, the model produces positive net growth, though the global growth rate has been slowing.
