Answers
767.35 crores (2019)
You may think of the global population as a massive, exponentially-growing number of people that threaten to use up all of the world's resources, but that's not the case.
There are approximately 7.8 billion people in the world as of July 2020, according to a 2020 report published in the journal The Lancet.
The global population is an estimate of the total number of people living on the planet, rather than a true running total of every baby born minus every person who has died at a given moment in time.
Because it's impossible to keep track of the real-time numbers of births and deaths worldwide, demographers, or statisticians that study human populations, calculate the world's population by adding up estimates of regional populations, according to the United Nations. They arrive at these regional estimates by taking into account a variety of factors, including fertility rate, or the average number of children that a woman has in her lifetime, and mortality rate, or a person's life expectancy, given the social and economic conditions of the region.
