How Many Humans Have Ever Lived?
How Many Humans Have Ever Lived?
In 2022, the world will likely hit a momentous milestone—a population of eight billion.
Of course, this dramatic increase in the world’s human population is a relatively new phenomenon. For many thousands of years, there were fewer people roaming the Earth than would live in a mid-sized city today.
But this does raise an interesting question, though: over the long arc of human history, how many people have ever lived?
The unique and powerful visualization above, from the team at Our World in Data, highlights how many humans have ever lived, and how much of humanity is currently alive today.
Quantifying Our Ancestors
How many humans came before us? This is the question demographers like Toshiko Kaneda and Carl Haub have attempted to answer.
Quantifying all of humanity requires a firm starting date for when humans became, well, human. Evolution is a gradual process, so figuring out the start date for humankind is no easy task. For the purposes of this exercise, however, the two demographers used 190,000 BCE as the cutoff.
There are two opposing points to consider when thinking about prehistoric humans:
- Around the chosen start date, the global cohort of humans was quite small—perhaps as low as only 30,000 individuals.
- Before the modern era, lifespans were much shorter, so long stretches of time can actually influence numbers drastically.
With this context and timeframe in mind, the demographers estimate that 109 billion people have lived and died over the course of 192,000 years. If we add the number of people alive today, we get 117 billion humans that have ever lived.
This means that for every person alive today, there are approximately 14 people who are no longer with us.
It is these 109 billion people we have to thank for the civilization that we live in. The languages we speak, the food we cook, the music we enjoy, the tools we use – what we know we learned from them. –Max Roser, Our World in Data
How Much of Humanity is Currently Alive Today?
When considering that 7% of all humans who have ever lived are alive today, especially when measuring across more than a thousand centuries, it’s remarkable that such a large portion of humans are currently living.
If we chart the recent global population explosion though, it begins to make sense.
Looking at the chart above, it’s hard to predict which path humanity will go down in the future, and how that will affect future population growth.
It was only in 2007 that the majority of humans began to live in cities, and in 2018 that the majority gained access to the internet. While we’ll never meet the 109 billion humans who laid the foundation for our modern societies, we’ve never been more connected as a species.
What will we do with our time in the top of the hour glass?

History
Vintage Viz: China’s Export Economy in the Early 20th Century
This pie chart, circa 1914, is a fascinating breakdown of China’s export economy just prior to World War I.

Vintage Viz: China’s Export Economy in the Early 20th Century
“The past is a foreign country; they do things differently there” is the oft-quoted first line of L.P. Hartley’s 1953 novel, The Go-Between.
A statement that is as profound as it is banal. In other words, when we do history, we’re a bit like tourists. If we really want to understand the past, we have to think like a local.
The infographic above, Aspects of Principal Exports of Chinese Goods to Foreign Countries, is the first in a series that we’re calling Vintage Viz, which presents a historical visualization along with the background and analytical tools to make sense of it.
Today, the People’s Republic of China is the second largest economy in the world, a permanent member of the UN Security Council, and a growing military power. But at the dawn of the 20th century, things were much, much different.
Opium and the Opening of China to the West
Early Sino-Western trade was restricted by the Qing emperors to three ports, and after 1757, just one, in what became known as the Canton System. This name came from the one remaining port city of the same name, present-day Guangzhou.
Foreign trade was tightly monitored and subject to stiff tariffs, and Western traders chafed under these restrictions. So when in 1839, Chinese authorities moved to shut down opium smuggling—an important source of profit for foreign merchants—Western powers saw their chance and used the pretext to revise the terms of trade by force.
In what became known as the Opium Wars, 1839-1842 and 1856-1860, first Great Britain and then an Anglo-French alliance defeated imperial China and imposed punitive treaties that included indemnities and lowered tariffs, but also expanded the number of ports open to foreign traders, first to five and by 1911, to more than 50.
Westerners were exempted from local laws, Christian missionaries were allowed to proselytize freely, and the opium trade was legalized. Hong Kong was also ceded to Great Britain at this time.
The Treaty Port Era, also known as the Century of Humiliation, was perhaps too much for the country to bear. The weakened central government was beset by popular unrest, including the Taiping Rebellion (1850–64), which killed 20 million people, and the Boxer Rebellion (1899-1901), so-named for the secret society that led the movement, the Righteous and Harmonious Fists.
Eventually, the last Chinese emperor was deposed and a republic declared in 1911. Nevertheless, the government was too weak to impose its will, and was repeatedly challenged by warlords.
So as we approach the outbreak of the First World War in 1914, and the period covered by our visualization, we find China weakened internally by civil strife, and externally by Western powers.
The History of this Century-Old Pie Chart
Aspects of Principal Exports of Chinese Goods to Foreign Countries captures Chinese exports for 1914, and comes from The New Atlas and Commercial Gazetteer of China: A Work Devoted to Its Geography & Resources and Economic & Commercial Development.
Originally published in 1917 and edited by Edwin J. Dingle for the Far Eastern Geographical Establishment, the volume contains a wealth of data for the period. According to the book’s Preface, it “seeks to give all the information that is essential to the business-man in regard to a country… about which less is known than in regard to any similar area in the world.”
The visualization breaks down total Chinese exports for 1914 in haikwan taels (hk. tls.), a unit of silver currency used to collect tariffs. In 1907, one haikwan tael was worth $0.79 U.S. dollars.
Official figures come from the Chinese Maritime Customs Service. This was set up by foreign consuls after the First Opium War to collect tariffs to guarantee the payment of treaty indemnities.
Exports in 1914 represented 345 million hk. tls., a 14.4% decrease from 1913, likely owing to the outbreak of the First World War that same year.
Apart from “Other Metals and Minerals, Sundries, etc,” which served as a catch-all category, the largest categories were silks and teas of various types, representing 22.6% and 10.4% of total exports respectively.

Below are some more details that emerge from this visualization.
All the Tea in China
The Chinese tea trade was the subject of another visualization in the Atlas. It shows that China had been steadily losing ground to British India. Between 1888-1892 Chinese exports to Great Britain were 242 million pounds against India’s 105 million pounds. By 1912-1913, India had surpassed China to export 279 million pounds against 198 million pounds.
In 1914, the majority of Chinese exports went to Russia, 902,716 piculs in all. A picul is equal to “as much as a man can carry on a shoulder-pole” or about 133 pounds.
The Silk Road to Profits
Silk has long been in demand in the West as a luxury good, giving its name to the overland trade route that connected East and West for centuries: the Silk Road.
In 1914, China was the largest producer and exporter of silks in the world. On an annual basis, China averaged 14 million pounds, compared to the number two spot, Japan, at 11 million pounds, and number three, Italy, at 9 million pounds. Together, these three controlled 81.7% of the global silk trade.
The Opium of the Masses?
The opium trade, the pretext that opened China to foreign trade, was still big money in 1914.
A total of 37 million hk. tls. were imported in 1914 from India, up 11.9% from 1908. This is actually down from a peak of 41 million hk. tls. in 1913.
In 1907, China signed the Ten Year Agreement with India, which ultimately phased out the opium trade. By 1917 the trade was all but extinguished.
Back to the Future
The Aspects of Principal Exports of Chinese Goods to Foreign Countries is a far cry from the contemporary trade picture. China’s top export in 2021 was in the category “telephones for cellular networks or other wireless networks,” and was worth $147.1 billion.
But it’s worth noting that China today is a direct result of this period. The resentment created during the Century of Humiliation would eventually help lead to Mao Zedong, the Long March, and the establishment of the People’s Republic of China.
And in 1979, the Chinese central government would set up the first of their own “treaty ports,” in the form of special economic zones, places where foreign companies could set up shop. But this time, it wasn’t foreign powers who were making the rules.
