The current world population is 7.9 billion as of August 2021 [ 1] according to the most recent United Nations estimates elaborated by Worldometer. The components of population change have not been adjusted and so inconsistencies will exist between population values derived directly from the components and the population displayed in the odometer and the Select a Date tool. Others have estimated the number of human beings who have ever lived to be anywhere from 45 billion to 125 billion, with most estimates falling into the range of 90 to 110 billion humans. Water draining out is deaths.

Second of the three institutions is Austria's Wittgenstein Centre for Demography and Global Human Capital.

Figures include the former Soviet countries in Europe. What do our growing numbers mean for economic security, climate change, environmental destruction and the likelihood of pandemics? [80], According to the World Health Organization, the global average life expectancy is 71.4 years as of 2015, with women living an average of 74 years and men approximately 69 years. The development will put enormous pressure on Earth's resources and we'll need to find more sustainable ways of living.
