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 ...
High, medium, and low projections of the future human world population [1] In world demographics, the world population is the total number of humans currently alive. 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 ...
Earth has a human population of over 8 billion as of 2024, with an overall population density of 50 people per km 2 (130 per sq. mile). Nearly 60% of the world's population lives in Asia, with more than 2.8 billion in the countries of India and China combined. The percentage shares of China, India and rest of South Asia of the world population ...
A Valeriepieris circle [1] [2] [3] is a figure drawn on the Earth's surface such that the majority of the human population lives within its interior. The concept was originally popularized by a map posted on Reddit in 2013, made by a Texas ESL teacher named Ken Myers, whose username on the site gave the figure its name. [ 4 ]
World population milestones went unnoticed until the 20th century, since there was no reliable data on global population dynamics. [2] The population of the world reached. [3][4] Old estimates put the global population at 9 billion by 2037–2046, 14 years after 8 billion, and 10 billion by 2054–2071, 17 years after 9 billion; however these ...
During the 14th century, there was a fall in population associated with the Black Death that spread from Asia to Europe. This was followed by a period of restrained growth for 300 years. [6] John F. Richards estimated the following world populations from the early modern period, 1500–1800. [7] 1500 world population 400-500 million
The table below shows that from 2020 to 2050 and beyond to 2100, the bulk of the world's population growth is projected to take place in Africa. Of the additional 1.9 billion people projected between 2020 and 2050, 1.2 billion will be added in Africa, 0.7 billion in Asia and zero in the rest of the world.
Based on a dataset of average population density of hunter-gatherer groups collected by Lewis R. Binford, which indicate a mean density of 0.1223 humans per km 2 and a median density of 0.0444 humans per km 2, the combined human population of Africa and Eurasia at the time of the LGM would have been between 2,998,820 and 8,260,262 people.
