Current World Population
World population is the number of people alive on Earth right now, roughly 8.3 billion. A population clock estimates it as base count + (births - deaths) x seconds elapsed. With 132 million births and 62 million deaths a year, that is +70 million people annually, or about 2.2 extra people every second.
World population on any date
Pick any day between 1200 and 2100 to see how many people were alive then, how many have been added since, and how much bigger humanity is today.
Figures before 1750 are rough historical estimates and can vary by 15% between sources; 1750-1949 follow the US Census Bureau compilation, 1950 onward the UN World Population Prospects 2024 estimates and medium projection.

Population Milestones
What is the world population right now?
The counter above passes 8.3 billion during 2026. The UN put the world at 8.2 billion in mid-2024 and 8.23 billion in mid-2025, growing by about 70 million people a year. No one counts everyone in real time: the figure is a census-based estimate carried forward second by second, so treat the last three digits as decoration and the first three as the news.
How is the world population calculated?
National censuses and household surveys give the base count. The UN Population Division reconciles them with birth, death and migration registers and publishes World Population Prospects every two years. A clock like this one starts from that baseline (8,196,800,000 on 1 January 2025, the midpoint of the UN's mid-2024 and mid-2025 totals), adds 132 million births a year, subtracts 62 million deaths, and spreads the +70 million net over 31,557,600 seconds: 2.2 people per second.
When did the world population reach 8 billion?
The United Nations marked 15 November 2022 as the Day of Eight Billion. The seventh billion arrived in 2011 and the sixth in 1999, so the last two billions each took about eleven to twelve years. The date is symbolic rather than exact: the underlying estimate carries an uncertainty of tens of millions, comfortably more than a single day of growth.
How long the world took to add each billion people
| Milestone | Reached | Years since previous billion | Growth rate then |
|---|---|---|---|
| 1 billion | 1804 | - | 0.51% |
| 2 billion | 1927 | 123 | 1.08% |
| 3 billion | 1960 | 33 | 2.05% |
| 4 billion | 1974 | 14 | 1.87% |
| 5 billion | 1987 | 13 | 1.82% |
| 6 billion | 1999 | 12 | 1.48% |
| 7 billion | 2011 | 12 | 1.17% |
| 8 billion | 15 November 2022 | 11 | 0.86% |
| 9 billion | 2037 (projected) | 15 | 0.69% |
| 10 billion | 2061 (projected) | 24 | 0.20% |
The first eight rows are the dates usually given for each billion. The first four are retrospective estimates from the UN's The World at Six Billion (1999), worked out long after the fact; 1987, 1999, 2011 and 2022 are the UN's Day of Five, Six, Seven and Eight Billion, announced at the time. The series behind the lookup, the UN's 2024 revision interpolated between anchor years, passes the fifth to eighth billions about one to two years before those announcements, so entering an announced date returns a little more than the round number: 8.05 billion for 15 November 2022. The first and fourth milestones run the other way, returning 998 million for 1804 and 3.98 billion for 1 July 1974. The growth-rate column is the average annual growth of that same series across the interval containing the year shown; from 1950 onward that is exactly the figure the year table below prints for that interval. Rows nine and ten are the UN medium projection.
Will the world population reach 9, 10 or 20 billion?
Nine billion is expected around 2037 and ten billion in 2061. The UN medium projection then flattens: a peak near 10.3 billion in the mid-2080s, followed by a slow decline to about 10.2 billion in 2100. Twenty billion is not on any mainstream projection, because global fertility has fallen to roughly 2.2 births per woman and keeps sliding.

Which country has the biggest population?
India, with about 1.46 billion people, overtook China in April 2023 and now holds roughly 17.8% of humanity. China follows with 1.42 billion, then the United States at 347 million, Indonesia at 286 million and Pakistan at 255 million. The top ten countries together hold about 57% of everyone alive; the table above gives each country's share of the mid-2025 world total.
What was the world population when I was born?
Type your birthday into the date lookup above. It interpolates between UN and US Census Bureau anchor years, so a birth on 1 July 1980 returns about 4.45 billion, 1 July 2000 about 6.17 billion, and 1 July 2010 about 7.02 billion. The tool also shows how many people have been added since and how many times larger the world is today.

About Current World Population
This world population clock turns the UN World Population Prospects dataset into a number you can watch move. The baseline is 8,196,800,000 people on 1 January 2025, the midpoint of the UN's mid-2024 and mid-2025 world totals rather than a figure the UN publishes for that day; from there the page adds 132 million births and removes 62 million deaths per year, which works out at 4.2 births and 2.0 deaths every second and a net gain of about 2.2 people per second, nearly 8,000 per hour and 70 million per year. The four cards under the odometer restart at midnight UTC, so you can see exactly how much the current day has contributed.
Below the counter, the births and deaths panels break the same rates down per second, minute, hour, day and year, the top ten countries are shown with their share of the mid-2025 world total, and the milestone grid records the year humanity crossed each billion, from 1804 to the Day of Eight Billion on 15 November 2022.
What sets this page apart from a plain counter is the date lookup: choose any day between 1200 and 2100 and it interpolates between historical estimates and the UN medium projection to tell you how many people were, or will be, alive then, how many have been added since and how many times larger the world has become. Every anchor year can be downloaded as CSV or copied as a table for a spreadsheet, a lesson plan or a slide.
Nothing is sent to a server: the clock, the lookup and the export all run in your browser, which is why the numbers keep ticking even on a slow connection. Remember that no counter observes births as they happen. Every figure here is a projection from census data, accurate to within tens of millions, so it is best read as a scale, not a headcount.
Use Cases
How to use
Watch the odometer at the top: it starts from the UN baseline and adds about 2.2 people every second.
Read the Births Today, Deaths Today, Growth Today and Growth/sec cards to see what the current UTC day has added.
Enter a date in the "World population on any date" panel to get the estimate for that day, from 1200 to 2100.
Use Download CSV or Copy as table to take the anchor years into a spreadsheet or a slide.
Scroll to the country table for each nation's share of the world total, and to the milestone table for the year humanity crossed each billion.
Pro Tips
- The odometer is an extrapolation, not a headcount. Quote it as "about 8.3 billion" rather than to the last digit.
- Use the date lookup for anniversaries: it answers "how many people were alive in 1969?" (3.62 billion) in one click.
- Divide the live count by 100 for a quick 1% of humanity, a useful yardstick when a statistic is quoted in millions.
- The Growth Today card resets at 00:00 UTC, not at your local midnight, so it can look low early in the American evening.
- Download the CSV before a presentation: the anchor years let you rebuild the same curve offline, without the live script.
Frequently Asked Questions
It is still increasing, but more slowly every year. Growth peaked in the mid-1960s at about 2.3% a year and is now near 0.85%, roughly 70 million extra people annually. More than half of countries already have fertility below replacement level, and the UN expects the global total to stop growing in the mid-2080s before edging down.
Around 1 to 10 million, according to the US Census Bureau compilation of historical estimates; most demographers use 4 to 5 million for 8000 BC. That is fewer people than live in Sydney today. It took until roughly 1804 for the total to reach one billion, and only 218 years more to reach eight.
About 450 million when Columbus crossed the Atlantic, roughly 5.5% of today's total and about the same as the European Union today. Estimates for that period vary by 15% between sources because they rest on tax records and archaeology rather than censuses. The lookup above returns about 453 million for 1492.
The UN projects 9 billion around 2037, about 15 years after the eighth billion arrived on 15 November 2022. The gaps have stopped shrinking: the seventh billion took 12 years, the eighth 11, and the ninth is expected to take 15. The tenth is not projected until 2061, another 24 years later.
About 4.2, from roughly 132 million births a year. Deaths run at about 2.0 per second, or 62 million a year, so the net gain is 2.2 people per second: 133 per minute, nearly 8,000 per hour and about 192,000 per day. The Births and Deaths panels on this page show every one of those conversions.
Asia holds about 59% of humanity, roughly 4.8 billion people, and Africa another 19%. Close to 90% of everyone lives in the Northern Hemisphere, and about a third of the world lives in just two countries, India and China. The UN's 2024 revision expects more than a fifth of all growth between 2024 and 2054 to come from nine fast-growing countries, most of them in sub-Saharan Africa.
The trend is reliable, the last digits are not. It extrapolates from 8,196,800,000 people on 1 January 2025, the midpoint of the UN's mid-2024 and mid-2025 estimates rather than a figure the UN publishes for that day, using fixed yearly rates, so it cannot see a birth as it happens. Independent estimates from the UN and the US Census Bureau differ by tens of millions, which is several months of growth. Round to the nearest 100 million when quoting it.
About 9.7 billion in the UN medium projection, some 1.4 billion more than the 8.23 billion of mid-2025. That is an average of 57 million extra people a year, well below the peak of about 93 million added in 1990. A projection is not a forecast: the medium variant assumes global fertility keeps falling from today's 2.2 births per woman, and the year table above shows annual growth sliding from 0.8% now to 0.3% by 2050.
No mainstream projection reaches it. The UN medium scenario peaks near 10.3 billion in the mid-2080s and comes back to 10.2 billion in 2100, and the top of its 95% prediction interval for that year is 11.4 billion, barely past half of 20 billion. Reaching 20 billion would require global fertility to rise well above 2.5 births per woman and stay there, the opposite of the trend recorded on every continent since 1965.
About 83 million people, roughly the population of Germany. One tenth of a percent is 8.3 million, about the size of New York City, and one in a million is around 8,300 people. Divide the live counter above by 100 whenever you need to turn a statistic in millions into a share of humanity.
