Published estimates for the 1st century ("AD 1") suggest uncertainty of the order of 50% (estimates range between 150 and 330 million). Some estimates extend their timeline into deep prehistory, to " 10,000 BC", i.e., the early Holocene, when world population estimates range roughly between 1 and 10 million (with an uncertainty of up to an ...

[23] Although Ehrlich was not the first to warn about population issues — concern had been widespread during the 1950s and 1960s — his charismatic and media ...
The UN Population Division has calculated the future population of the world's countries, based on current demographic trends. In 2022, world population reached 8 billion. The UN's 2022 report projects world population to be 9.7 billion people in 2050, and about 10.3 billion by 2100.
The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999. It reached the 2 billion mark in 1927, the 3 billion mark in 1960, 4 billion in 1974, and 5 billion in 1987. The overall population of the world is approximately 8 billion as of November 2022.
v. t. e. The Limits to Growth (often abbreviated LTG) is a 1972 report [2] that discussed the possibility of exponential economic and population growth with finite supply of resources, studied by computer simulation. [3] The study used the World3 computer model to simulate the consequence of interactions between the Earth and human systems.

In world demographics, the world population is the total number of humans currently living. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. It took around 300,000 years of human prehistory and history for the human population to reach a billion and only 218 years more to reach 8 billion.
