This year, world population hit a new milestone in human development as it reached 8 billion people across the Globe. This milestone was honored by the United Nations declaring November 15, 2022, “The Day of Eight Billion”.
To mark this event, we used our timeline creator tool to put together a visual chronology of key world population milestones from the 1800 to today. We also included some projections of population growth to show when statisticians predict that humanity will reach future milestones. Further down, you’ll also find the answers to some frequently asked questions about population growth.
The visual was built in PowerPoint using Office Timeline and the original file is available to download for free. You can use the picture in your presentations as an image or include it as an entire PowerPoint slide.
Until the 19th century, since there was no reliable way to track population growth and decline, scholars failed to record any world population milestones. There are now several organizations that track global population demographics, but for this article we chose the numbers proposed by the reputable United Nations Population Fund (UNFPA).
This is when the United Nations estimates that the world’s population reached each billion milestone:
one billion in 1804;
two billion in 1927 (123 years later);
three billion in 1960 (33 years later);
four billion in 1974 (14 years later);
five billion in 1987 (13 years later);
six billion in 1999 (12 years later);
seven billion in October 2011 (12 years later);
eight billion on November 15, 2022 (11 years later).
FAQs about world population
Here are the answers to the most frequent questions people ask related to world population growth.
It’s difficult to pinpoint the exact moment, but the United Nations proposedOctober 31, 2011, as a symbolic date for reaching the 7 billion milestone for global population. The day was chosen based on data incorporated from its estimates over a 5-year period.
When did we reach 8 billion?
The United Nations stated that global population probably reached 8 million on November 15, 2022. The date is approximate, as there is no official count, only estimates. The UN announced that its projections indicated we should have passed the 8-billion threshold around this date.
What year will we reach 10 billion?
Researches differ in their projections according to various statistical models, but the United Nations estimates that we will reach 10 billion in world population in 2059. Other simulations suggest dates like 2054, 2056, or 2058. In any case, most projections indicate the late 2050s as the probable date for reaching the 10 billion milestone.
What was the population 100 years ago?
At the beginning of the 20th century, world population was probably around 2 billion people. However, statistics from around that time are unreliable. This not surprising, since major events like the First World War and the outbreak of Spanish flu made it difficult to register population deaths and births correctly.
What will the world population be at by 2050?
United Nation reports predict that world population in 2050 will be around 9.7 billion people. The same study suggests that human population will peak at nearly 11 billion around 2100.
About the world population milestone timeline
The visual timeline presenting the major global population milestones was created using Office Timeline, a user-friendly add-in for PowerPoint that takes your list of milestones and arranges them into easy-to-understand timelines. You can download the timeline as a PowerPoint file for free and update the milestones either manually, or automatically with the free 14-day trial from Office Timeline.
When Did the World Population Reach Other Milestones? It took 123 years to reach 2 billion, and only 33 years to reach 3 billion. The last several billion milestones (4, 5, 6, 7, and 8 billion) were reached in 14, 13, 11, 12, and 12 years, respectively.
The United Nations stated that they "can't predict which exact baby will push us into the next billion". Nonetheless, the Philippines' Commission on Population and Development selected Vinice Mabansag, a baby girl born in Manila, as the symbolic eight billionth person on Earth.
This is when the United Nations estimates that the world's population reached each billion milestone: one billion in 1804; two billion in 1927 (123 years later); three billion in 1960 (33 years later);
World population did not reach one billion until 1804. It took 123 years to reach 2 billion in 1927, 33 years to reach 3 billion in 1960, 14 years to reach 4 billion in 1974 and 13 years to reach 5 billion in 1987. 5.
There are many sources of uncertainty in estimating the global population, and it's unlikely this population milestone was reached on that exact date. For example, the United Nations (U.N.) Population Division estimates the world population reached 8 billion on November 15, 2022.
The UN estimated that the world population reached one billion for the first time in 1804. It was another 123 years before it reached two billion in 1927, but it took only 33 years to reach three billion in 1960.
In 1999, a baby boy born in Sarajevo, Bosnia-Herzegovina, was symbolically designated as the six billionth baby by UN Secretary General Kofi Annan. The family of baby Adnan Nevic years later told media that the honor was pretty useless. Postmedia archives; photo credit: UN Photo/Milton Grant.
Matej Gašpar from Zagreb, Croatia (then SR Croatia, SFR Yugoslavia), was chosen as the symbolic 5-billionth person alive on Earth. The honor went to Zagreb because the 1987 Summer Universiade was taking place in the city at the time.
As demographers have estimated humanity hit a global population of more than 8 billion people on Tuesday, the world's symbolic 8 billionth baby was born in the Philippines. Vinice Mabansag, who was born on Nov. 15 at the Dr.
We decided to name her Vinice after Vincent's nickname, Vin. We were so happy that we were able to have baby Vinice without any complications, even if life has been difficult for us.
Approximately 70,000,000 is one percent of the world's population. To estimate the number of the resident population in a certain territory, governments conduct censuses.
United Nations Population Division Projection: The United Nations (UN) projects that the world population will peak around 2100 at approximately 11 billion and then start to decline [1]. If current trends continue, it is suggested that there may be no people left by the year 3000 [1].
According to data from the United Nations' 2022 Revision of its World Population Prospects, we could see a peak of over 10.4 billion people sometime in the late 2080s. While the UN's projections are the most widely used, this doesn't necessarily mean they're the most accurate.
The current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100, according to a new United Nations report being launched today.
The world's population is expected to increase by nearly 2 billion persons in the next 30 years, from the current 8 billion to 9.7 billion in 2050 and could peak at nearly 10.4 billion in the mid-2080s.
