The chart above illustrates how world population has changed throughout history. View the full tabulated data.
At the dawn of agriculture, about 8000 B.C., the population of the world was approximately 5 million. Over the 8,000-year period up to 1 A.D. it grew to 200 million (some estimate 300 million or even 600, suggesting how imprecise population estimates of early historical periods can be), with a growth rate of under 0.05% per year.
A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years (1930), the third billion in 30 years (1960), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987).

Yearly Population Growth Rate (%)
Population in the world is currently (2018) growing at a rate of around 1.09% per year (down from 1.12% in 2017 and 1.14% in 2016). The current average population increase is estimated at 83 million people per year.
Annual growth rate reached its peak in the late 1960s, when it was at around 2%. The rate of increase has nearly halved since then, and will continue to decline in the coming years. It is estimated to reach 1% by 2023, less than 0.5% by 2052, and 0.25% in 2076 (a yearly addition of 27 million people to a population of 10.7 billion). In 2100, it should be only 0.09%, or an addition of only 10 million people to a total population of 11.2 billion.
World population will therefore continue to grow in the 21st century, but at a much slower rate compared to the recent past. World population has doubled (100% increase) in 40 years from 1959 (3 billion) to 1999 (6 billion). It is now estimated that it will take another nearly 40 years to increase by another 50% to become 9 billion by 2037.
The latest world population projections indicate that world population will reach 10 billion persons in the year 2055 and 11 billion in the year 2088.
The United Nations projects world population to reach 10 billion in the year 2056.
World population is expected to reach 8 billion people in 2023 according to the United Nations (in 2026 according to the U.S. Census Bureau).
The current world population is 7.6 billion as of May 2018 [1] according to the most recent United Nations estimates elaborated by Worldometers. The term "World Population" refers to the human population (the total number of humans currently living) of the world.
According to the United Nations, world population reached 7 Billion on October 31, 2011.
The US Census Bureau made a lower estimate, for which the 7 billion mark was only reached on March 12, 2012.
According to the United Nations, the 6 billion figure was reached on October 12, 1999 (celebrated as the Day of 6 Billion). According to the U.S. Census Bureau instead, the six billion milestone was reached on July 22, 1999, at about 3:49 AM GMT. Yet, according to theU.S. Census web site, the date and time of when 6 billion was reached will probably change because the already uncertain estimates are constantly being updated.
1 - 1804 (1803 years): 0.2 to 1 bil.
1804 - 2011 (207 years): from 1 billion to 7 billion

It was written during the 1970s that 75% of the people who had ever been born were alive at that moment. This was grossly false.
Assuming that we start counting from about 50,000 B.C., the time when modern Homo sapiens appeared on the earth (and not from 700,000 B.C. when the ancestors of Homo sapiens appeared, or several million years ago when hominids were present), taking into account that all population data are a rough estimate, and assuming a constant growth rate applied to each period up to modern times, it has been estimated that a total of approximately 106 billion people have been born since the dawn of the human species, making the population currently alive roughly 6% of all people who have ever lived on planet Earth.
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.
The world population counter displayed on Worldometers takes into consideration data from two major sources: the United Nationsand the U.S. Census Bureau.
The above world population clock is based on the latest estimates released on June 21, 2017 by the United Nations and will show the same number wherever you are in the world and whatever time you set on your PC. Worldometers is the only website to show live counters that are based on U.N. data and that do not follow the user's PC clock.
Visitors around the world visiting a PC clock based counter, see different numbers depending on where they are located, and in the past have seen other world population clocks - such as the one hosted on a United Nations website and on National Geographic - reaching 7 billion whenever their locally set PC clocks reached 4:21:10 AM on October 31, 2011.
Obviously, the UN data is based on estimates and can't be 100% accurate, so in all honesty nobody can possibly say with any degree of certainty on which day world population reached 7 billion (or any other exact number), let alone at what time. But once an estimate is made (based on the best data and analysis available), the world population clock should be showing the same number at any given time anywhere around the world.
