Mongolia may be spearheading a three-word address revolution

In 2015, we interviewed the Marketing Director of what3words, a promising startup participating in Boost, TNW Conference's early stage startup program. We recognized the startup's potential but didn't anticipate that, just one year after our conference, they'd already be making international headlines.

what3words has made a global grid of 57 trillion 3mx3m squares, and each square has a unique three-word phrase assigned to it that can be communicated quickly, easily and without ambiguity.

The service's geocoder turns geographic coordinates into these three-word addresses and vice-versa. So, if you want to tell your friends to meet you in Central Park at the third tree to the left of that second lake thing, right next to the fighting hobos, you'd simply tell them to go to active.exact.worker.

Where the party's at. Picture courtesy of What3words.

Using words means non-technical people can accurately find any location and communicate it more quickly, more easily and with less ambiguity than any other system like street addresses, postcodes, latitude and longitude, or mobile short-links.

Pretty sweet, huh? The people of Mongolia thought so too, because the service can be used for more important matters than finding your friends in a park.

Around 75 percent of the world (135+ countries) suffers from inadequate addressing, which leaves four billion people invisible, unable to get deliveries or receive aid, and unable to exercise their rights as citizens.

One of the countries hit hardest by the traditional mail system is Mongolia, known for its vast, sparsely populated landscape (three times the size of Spain) and nomadic population. Many Mongolians are forced to travel several miles to collect their mail from post office boxes because their homes are not listed in the national postal system.

The country's largest postal service provider, Mongol Post, serves more than 3 million citizens, of which 30 percent are nomadic. It's also in the country's economic interest to have a functioning address system: as a rapidly emerging market set on attracting interest, what3words seems to offer the perfect solution.

Mongol Post will be the first national postal service to start using what3Word's system next month. What this means is that what3words will be paid to provide a software that converts three-word addresses into GPS coordinates. Mail will have its three-word address converted into GPS coordinates, and off it goes. Then, using the free what3Words website or app, users can look up these three-word locations, which have been translated into Mongolian.

Where old meets new: Ulaanbaatar, Mongolia's capital.

If successful, there's no reason to doubt more countries will follow.

It comes as no surprise that what3words recently received $3.5M led by Intel Capital to simplify location sharing and won the Innovation Lions Grand Prix at Cannes.

We complain about gas prices and the rising costs of milk and eggs but have you ever thought how much you would have to spend if you lived in another country. The infographic below shows the price of some familiar products in the U.S. and in other countries.

All of the examples show the U.S. as having the cheaper price. If you were to buy an Iphone in Russia you would spend over $1000. That is insane to us as Americans but what is even crazier is that a two-liter drink would cost almost $20 in Sao Paulo. The prices of our products may go up a few dollars or drop a few but if all of our prices jumped as high as they are in other countries we would be outraged

Being able to compare the cost of goods in the U.S. to other countries is a good way to appreciate what we do have. We are able to afford these prices in the U.S, but if we were living in another country would we be able to afford these things?

The world's population is now odds-on to swell ever-higher for the rest of the century, posing grave challenges for food supplies, healthcare and social cohesion. A ground-breaking analysis released on Thursday shows there is a 70% chance that the number of people on the planet will rise continuously from 7bn today to 11bn in 2100.

The work overturns 20 years of consensus that global population, and the stresses it brings, will peak by 2050 at about 9bn people. "The previous projections said this problem was going to go away so it took the focus off the population issue," said Prof Adrian Raftery, at the University of Washington, who led the international research team. "There is now a strong argument that population should return to the top of the international agenda. Population is the driver of just about everything else and rapid population growth can exacerbate all kinds of challenges." Lack of healthcare, poverty, pollution and rising unrest and crime are all problems linked to booming populations, he said.

"Population policy has been abandoned in recent decades. It is barely mentioned in discussions on sustainability or development such as the UN-led sustainable development goals," said Simon Ross, chief executive of Population Matters, a thinktank supported by naturalist Sir David Attenborough and scientist James Lovelock. "The significance of the new work is that it provides greater certainty. Specifically, it is highly likely that, given current policies, the world population will be between 40-75% larger than today in the lifetime of many of today's children and will still be growing at that point," Ross said.

Many widely-accepted analyses of global problems, such as the Intergovernmental Panel on Climate Change's assessment of global warming, assume a population peak by 2050.

Sub-saharan Africa is set to be by far the fastest growing region, with population rocketing from 1bn today to between 3.5bn and 5bn in 2100. Previously, the fall in fertility rates that began in the 1980s in many African countries was expected to continue but the most recent data shows this has not happened. In countries like Nigeria, the continent's most populous nation, the decline has stalled completely with the average woman bearing six children. Nigeria's population is expected to soar from 200m today to 900m by 2100.

The cause of the stalled fertility rate is two-fold, said Raftery: a failure to meet the need for contraception and a continued preference for large families. "The unmet need for contraception - at 25% of women - has not changed in for 20 years," he said. The preference for large families is linked to lack of female education which limits women's life choices, said Raftery. In Nigeria, 28% of girls still do not complete primary education.

Another key factor included for the first time was new data on the HIV/AIDS epidemic showing it is not claiming as many lives as once anticipated. "Twenty years ago the impact on population was absolutely gigantic," Raftery said. "Now the accessibility of antiretroviral drugs is much greater and the epidemic appeared to have passed its peak and was not quite as bad as was feared."

The research, conducted by an international team including UN experts, is published in the journal Science and for the first time uses advanced statistics to place convincing upper and lower limits on future population growth. Previous estimates were based on judgments of future trends made by researchers, a "somewhat vague and subjective" approach, said Raftery. This predicted the world's population would range somewhere between 7bn and 16bn by 2100. "This interval was so huge to be essentially meaningless and therefore it was ignored," he said.

But the new research narrows the future range to between 9.6bn and 12.3bn by 2100. This greatly increased certainty - 80% - allowed the researchers to be confident that global population would not peak any time during in the 21st century.

Another population concern is the ageing populations currently seen in Europe and Japan, which raises questions about how working populations will support large numbers of elderly people. But the new research shows the same issue will affect countries whose populations are very young today. Brazil, for example, currently has 8.6 people of working age for every person over 65, but that will fall to 1.5 by 2100, well below the current level in Japan. China and India will face the same issue as Brazil, said Raftery: "The problem of ageing societies will be on them, in population terms, before they know it and their governments should be making plans."

In separate work, published on Monday, Wolfgang Lutz, director of the Vienna Institute of Demography, highlighted education as crucial in not only reducing birth rates but also enabling people to prosper even while populations are growing fast. In Ghana, for example, women without education have an average of 5.7 children, while women with secondary education have 3.2 and women with tertiary education only 1.5. But he said: "It is not primarily the number of people that's important in population policy, it's what they are capable of, their level of education, and their health."

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.

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).

7.9 Billion (2022)

The current world population is 7.9 billion as of February 2022 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.
