World Population: Past, Present, and Future

(move and expand the bar at the bottom of the chart to navigate through time)

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).

During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion.

In 1970, there were roughly half as many people in the world as there are now.

Because of declining growth rates, it will now take over 200 years to double again.

Wonder how big was the world's population when you were born?
Check out this simple wizard or this more elaborated one to find out.

Growth Rate

Population in the world is currently (2020) growing at a rate of around 1.05% per year (down from 1.08% in 2019, 1.10% in 2018, and 1.12% in 2017). The current average population increase is estimated at 81 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.

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 2057.

World Population Milestones

10 Billion (2057)

The United Nations projects world population to reach 10 billion in the year 2057.

9 Billion (2037)

World population is expected to reach 9 billion in the year 2037.

8 Billion (2023)

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).

7.8 Billion (2020)

The current world population is 7.8 billion as of November 2020 according to the most recent United Nations estimates elaborated by Worldometer. The term "World Population" refers to the human population (the total number of humans currently living) of the world.

7 Billion (2011)

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.

6 Billion (1999)

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 the U.S. Census, the date and time of when 6 billion was reached will probably change because the already uncertain estimates are constantly being updated.

World Population by Religion

According to a recent study (based on the 2010 world population of 6.9 billion) by The Pew Forum, there are:

2,173,180,000 Christians (31% of world population), of which 50% are Catholic, 37% Protestant, 12% Orthodox, and 1% other.

1,598,510,000 Muslims (23%), of which 87-90% are Sunnis, 10-13% Shia.

1,126,500,000 No Religion affiliation (16%): atheists, agnostics and people who do not identify with any particular religion. One-in-five people (20%) in the United States are religiously unaffiliated.

1,033,080,000 Hindus (15%), the overwhelming majority (94%) of which live in India.

487,540,000 Buddhists (7%), of which half live in China.

405,120,000 Folk Religionists (6%): faiths that are closely associated with a particular group of people, ethnicity or tribe.

58,110,000 Other Religions (1%): Baha'i faith, Taoism, Jainism, Shintoism, Sikhism, Tenrikyo, Wicca, Zoroastrianism and many others.

13,850,000 Jews (0.2%), four-fifths of which live in two countries: United States (41%) and Israel (41%).

World Population by Country

How many people have ever lived on earth?

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.

World Population clock: sources and methodology

The world population counter displayed on Worldometer takes into consideration data from two major sources: the United Nations and the U.S. Census Bureau.

1. The United Nations Population Division of the Department of Economic and Social Affairs every two years calculates, updates, and publishes estimates of total population in its World Population Prospects series. These population estimates and projections provide the standard and consistent set of population figures that are used throughout the United Nations system.

The World Population Prospect: the 2019 Revision provides the most recent data available (released in June of 2019). Estimates and projected world population and country specific populations are given from 1950 through 2100 and are released every two years. Worldometer, as it is common practice, utilizes the medium fertility estimates.

Data underlying the population estimates are national and sub national census data and data on births, deaths, and migrants available from national sources and publications, as well as from questionnaires. For all countries, census and registration data are evaluated and, if necessary, adjusted for incompleteness by the Population Division as part of its preparations of the official United Nations population estimates and projections.

2. The International Programs Center at the U.S. Census Bureau, Population Division also develops estimates and projections based on analysis of available data (based on census, survey, and administrative information) on population, fertility, mortality, and migration for each country or area of the world. According to the U.S. Census Bureau, world population reached 7 billion on March 12, 2012.

For most countries adjustment of the data is necessary to correct for errors, omissions, and inconsistencies in the data. Finally, since most recent data for a single country is often at least two years old, the current world population figure is necessarily a projection of past data based on assumed trends. As new data become available, assumptions and data are reevaluated and past conclusions and current figures may be modified.

For information about how these estimates and projections are made by the U.S. Census Bureau, see the Population Estimates and Projections Methodology.

Why Worldometer clocks are the most accurate

The above world population clock is based on the latest estimates released in June of 2019 by the United Nations and will show the same number wherever you are in the world and whatever time you set on your PC. Worldometer 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.

Circus performers entertain with a wide variety of unusual acts that terrify, amuse, and amaze their audiences. Circus artists appear to defy death as they swing from a trapeze or walk a tightwire high above the ground. Some perform gymnastic feats on the ground, and clowns entertain with their absurd antics. Others train and perform with animals, such as elephants and tigers. Most circus performers are able to perform a variety of circus skills. Though "running away to join the circus" may seem like a fun way to earn a living, in reality, it is grueling, hard work.

#2: Wander through colorful Old San Juan

What kind of trip are you thinking about next?

Travel is changing day‑to‑day, which is why there's never been a better time to work with a local-someone who actually lives in the place you're visiting-to give you the inside scoop of what it's like on the ground!

So tell us what kind of trip you want to plan, and we'll connect you with the perfect local to get you started.

#3: Pop around Ponce, Puerto Rico's "Jewel of the South"

Located on Puerto Rico's southwestern coast, the city of Ponce is full of unique architectural gems and acclaimed museums. Don't miss the Parque de Bombas firehouse, the Hacienda Buena Vista Museum, or the city's beloved boardwalk, Tablado La Guancha.

Locals tell us that Ponce is also a great home base for day trips, as there are tons of unique places to visit within an hour radius. One of our Puerto Rico locals suggested checking out the lovely and isolated Gilligan's Island, which is about 50 minutes from Ponce.

#4: Discover Puerto Rico's soul in San Juan

Whether you're looking for a popping party or low key time in the sunshine, you'll find it in San Juan, Puerto Rico's beating heart. Here, you'll find distinct neighborhoods like Santurce, beautiful beaches like Isla Verde and Condado, and of course, lots of incredible food.

Locals recommend checking out attractions that give this part of the island its character. They suggest visiting the beautiful Raíces Fountain along Paseo de la Princesa and feeding the pigeons at Parque Las Palomas.

#9: Take in the beauty of Mayagüez

Mayagüez is known as the "Sultana of the West" for its gorgeous architecture and even more beautiful natural scenery. A 30-minute drive from Cabo Rojo on Puerto Rico's southwestern tip, Mayagüez is also accessible by plane through the Eugenio Maria Hostos Airport. From there, you can access prime snorkeling spots like Desecheo Island and Isla de Ratones.

#10: Dive through Spanish shipwrecks
Puerto Rico is known for its stunning blue waters, but even more amazing treasures lie beneath the surface. To snorkel past shipwrecks that date all the way from the 1500s, head over to Vieques or Rincon. You can also scuba-dive if you're certified.
#11: Explore Castillo San Felipe del Morro

#12: Surf with sea turtles in Rincon

#14: Stargaze at the Observatorio de Arecibo

Puerto Rico's is essentially a 20-acre dish-style telescope in the middle of the jungle. The interactive museum is especially cool to visit-and can be a neat stop if you want to visit Observatorio de Arecibo Puerto Rico with kids.

#19: Eat up Santurce's incredible food truck scene

Local Tip:

Barrachina offers a varied menu of genuine Puerto Rican food, from appetizers to entrées. It also happens to be a perfect place for events and celebrations, such as weddings, rehearsal dinners and many more.

#32: Hang out with horses on the black sand beaches of Vieques

On the island of Vieques-a quick ferry or plane ride for Puerto Rico proper-you'll find black sand beaches populated by 2,000 horses. The horses are not really wild, but they do have *free rein* of the place. Say hello, snap some pics, and enjoy digging your toes in the unique black sands.

While on Vieques, Mosquito Bay (known for its incredible bioluminescence) is also definitely worth a visit-although a popular spot among tourists. Get tips from locals: our Puerto Rico trip planners recommend checking out the kaleidoscopic Playa Cofi (Seaglass Beach) if you hope to get off the beaten path.

A guide to getting around once you land in Puerto Rico.

One of the most popular destinations in Puerto Rico for locals and visitors alike is El Yunque National Forest. This is the only tropical rainforest in the U.S. National Forest System and also one of the most biodiverse spots on the island thanks to the park's 240 different species of plants. Whether you're looking to go birdwatching, swim in natural pools under waterfalls, or test your endurance on a challenging hike, El Yunque has trails for all types of adventures. Some of the trails that are currently open include La Coca Trail, Baño Grande, Angelito and Puente Roto, El Toro, Mt. Britton, and El Yunque Peak. There are also a handful of options for tour companies who can arrange half-day or full-day trips from San Juan to the park, if you'd prefer to have experts handle the planning and driving.

Toro Negro State Forest

Jayuya/ Ponce/ Villalba/ Orocovis/ Ciales/ Juana Díaz

The nearly 7,000 acres of Toro Negro State Forest is spread over six different municipalities and includes four types of forest ( tabonuco, palm, Micropholis Buchenavia, and a cloud forest), the three highest peaks of the island (Cerro de Punta, Cerro Jayuya, and Cerro Rosa), a lake, two natural swimming pools, nine rivers, and numerous waterfalls. To hike and camp there, visit the ranger station on Route 143 KM 32.4 in Villalba. Most of the trailheads are concentrated in this area, and the most popular (and currently open) are El Bolo, which leads to a stone tower on the top of a mountain, and Charco La Confesora, which has a trailhead at the Toro Negro camping grounds.

Cambalache State Forest

The name of the mountain itself is Cerro de los Cielos but the trail gets its name from the solitary mango tree at the top which is visible from the highway
