Animated Map: Where Are the Largest Cities Throughout History?

Mapping the Largest Cities Throughout History

For much of human history, most people did not live in cities.

Cities—settlements that are densely populated and self-administered—require many specific prerequisites to come into existence. The most crucial, especially for much of human history, is an abundance of food.

Surplus food production leads to denser populations and allows for people to specialize in other skills that are not associated with basic human survival.

But that also means that cities usually consume more primary goods than they produce. And their size requires a host of many other services—such as transport and sanitation—that are traditionally expensive to maintain. So maintaining large urban centers, and especially the world’s largest cities, was a monumental task.

Mapper and history YouTuber Ollie Bye has visualized the seven largest cities in the world since 3,000 BCE. His video covers cities with a minimum population of 10,000 and hints at historical events which led to the establishment, growth, and eventual fall of cities.

The World’s Largest City Throughout History

With any historical data, accuracy is always a concern, and urban populations were rough and infrequent estimates up until the Industrial Revolution.

Bye has used a variety of data sources—including the UN and many research papers—to create the dataset used in the video.

In some places he also had to rely on his own estimates and criteria to keep the data reasonable and consistent:

  • In early history, some cities didn’t have given population estimates for long periods of time, and had to be equalized or estimated through other sources. For example, Babylon had a population estimate at 1,600 BCE (60,000) and at 1,200 BCE (75,000) but none in the 400 years between.
  • Cities that only briefly climbed above a population of 10,000, or that would have made the largest cities ranking for only a couple of years (and based on uncertain estimates), were not included.

Here’s a look at the largest city starting from the year 3,000 BCE, with populations listed in millions during the last year of each city’s “reign.” Cities are also listed with the flags of current-day countries in the same location.

Ancient Cities in the Fertile Crescent

Considered the “cradle of civilization,” the Fertile Crescent in the Middle East was home to all seven of the largest cities in the world in 3,000 BCE.

The Sumerian city of Uruk (modern-day Iraq), allegedly home to the legendary king Gilgamesh, topped the list with 40,000 people. It was followed by Memphis (Egypt) with 20,000 inhabitants.

For the next 1,700 years, other Mesopotamian cities in modern-day Iraq and Syria held pole positions, growing steadily and shuffling between themselves as the largest.

2,250 BCE marked the first time a different Asian city—Mohenjo-Daro (modern-day Pakistan) from the Indus Valley Civilization—found a spot at #4 with 40,000 people.

The table below is a quick snapshot of the seven largest cities in the world for from 3,000 BCE to 200 CE. Again, populations are listed in millions.

It wasn’t until 1,250 BCE that the top two spots were taken by cities in different regions: Pi-Ramesses (Egypt) and Yin (China), both with more than 100,000 residents.

Egyptian cities would continue to be the most populous for the next millennium—briefly interrupted by Carthage and Babylon—until the start of the Common Era. By 30 CE, Alexandria was the largest city in the world, but the top 10 had representatives from the Middle East, Northern Africa, and Asia.

All Roads Lead to Rome

One city in Europe meanwhile, was also beginning to see steady growth—Rome.

It took until halfway through the 3rd century C.E. for Rome to become the most populous city, followed closely still by Alexandria (Egypt). Meanwhile in Iraq, Ctesiphon, the capital of the Sasanian empire was growing rapidly.

Towards the end of the 3rd century, the Roman empire was divided into two, with Constantinople becoming the new capital for the Eastern half. Consequently, it had outgrown Rome by 353 and become the world’s most populous city, and for the next few centuries would reclaim this title time and time again.

The Largest Cities Reach 1 Million

In the 9th century, Baghdad became the first city to have 1 million residents (though historians also estimate Rome and the Chinese city of Chang’an may have achieved that figure earlier).

It would be nearly nine centuries until a city had one million inhabitants again, and Baghdad’s reign didn’t last long. By the 10th century, Bian, the capital of the Northern Song dynasty in China, had become the largest city in the world, with Baghdad suffering from relocations and shifting political power to other cities in the region.

From the 12th century onwards, Mongol invasions in the Middle East and Central Asia severely limited population growth in the region. European cities too were ravaged in the 14th century, but by plagues instead of marauders.

For the next few hundred years, Cairo (Egypt), Hangzhou (China), and Vijayanagara (India) would top the list until Beijing took (and mostly held onto) the top spot through the 19th century.

Industrial Revolution and Rapid Urbanization

The start of the Industrial Revolution in the UK—spreading to the rest of Europe and later on the U.S.—led to hitherto unseen levels of urban population growth.

Factories needed labor, which caused mass emigration from the rural countryside to urban centers of growth.

In 1827, London passed Beijing to become the largest city in the world with 1.3 million residents. Over the next 100 years, its population increased nearly 7 times, remaining the most populous city until the end of World War I, by which time it was overtaken by New York.

From 1920 to 2022, the world population quadrupled thanks to improvements in farming and healthcare, and cities saw rapid growth as well. The beginning of the 20st century saw the top 10 largest cities in the world in the U.S., Europe, and Japan.

By the 21st century however, growth shifted away to other parts of the world and by 2021, the top seven had cities only from Asia and the Americas.

Tokyo, which took the top spot in 1954, is the largest city in the world today with a population of 37 million (including the entire metropolitan area).

It is followed by New Delhi with 31 million, but by 2028, the UN estimates that positions will switch on the leaderboard and New Delhi will overtake Tokyo.

What Does Population Growth Say About the Past (and Future)?

The rise and fall of cities through the sands of time can give us insight into the trajectory of civilization growth. As civilizations grow, become richer, and reach their zenith, so too do their cities blossom in tandem.

For example, of the modern-day seven largest cities in the world, four of them belong to countries with the 10 largest economies in the world.

Meanwhile, sudden falls in urban population point to turbulence—political instability, wars, natural disasters, or disease.

Most recently Ukraine’s cities are seeing depopulation as residents flee conflict zones, raising the specter of a demographic crisis for the country should the war continue.

Thus, tracking the size of urban population can help policymakers forecast future roadblocks to growth, especially when prioritizing sustainable growth for a country.

Data note: The dataset uses the name of the city in that year, leading to the same city being named differently through the years.

Ranked: Countries Where Youth are the Most Unhappy, Relative to Older Generations

Conventional wisdom says that young adults (those below 30) tend to be the happiest demographic—but this is not true for these countries.

Countries with the Biggest Happiness Gaps Between Generations

“They say a person needs just three things to be truly happy in this world: someone to love, something to do, and something to hope for.” — Tom Bodett

Measuring happiness is tricky business, more so when taking into account how different regions, cultures, and faiths define it. Nevertheless, the World Happiness Report attempts to distill being happy into a single score out of 10, and then ranks countries by their average score.

We’ve visualized the high-level findings from the latest happiness report in this series of maps. However, the report also dives deeper into other significant trends in the data, such as a growing disparity in happiness between age groups within countries themselves.

In the chart above, we list countries by the biggest gaps in happiness ranks between young adults (<30) and older adults (60+). A higher number indicates a larger gap, and that the youth are far unhappier than their older counterparts.

Where are Youth Unhappier than Older Adults?

Mauritius ranks first on this list, with a massive 57 place gap between older adult and youth happiness. The 1.26 million-inhabited island nation briefly reached high income status in 2020, but the pandemic hit hard, hurting its key tourism sector, and affecting jobs.

The country’s youth unemployment rate spiked to close to 25% that year, but has since been on the decline. Like residents on many similarly-populated islands, the younger demographic often moves abroad in search of more opportunities.

Conventional wisdom says, and data somewhat correlates, that young adults (those below 30) tend to be the happiest demographic. Happiness then decreases through middle age and starts increasing around 60. However, the above countries are digressing from the pattern, with older generations being much happier than young adults.

That older generations are happier, by itself, is not a bad thing. However, that younger adults are so much unhappier in the same country can point to several unique stresses that those aged below 30 are facing.

For example, in the U.S. and Canada—both near the top of this list—many young adults feel like they have been priced out of owning a home: a once key metric of success.

Climate anxieties are also high, with worries about the future of the world they’ll inhabit. Finally, persistent economic inequities are also weighing on the younger generation, with many in that cohort feeling like they will never be able to afford to retire.

All of this comes alongside a rising loneliness epidemic, where those aged 18–25 report much higher rates of loneliness than the general population.

Where does this data come from?

Source: The World Happiness Report which leverages data from the Gallup World Poll.

Methodology: A nationally representative group of approximately 1,000 people per country are asked to evaluate their life on a scale of 0–10. Scores are averaged across generations per country over three years. Countries are ranked by their scores out of 10.
