These 3 Animated Maps Show the World’s Largest Cities Throughout History
In 300 B.C., Carthage was one of the world’s largest cities with up to 700,000 people living within its walls. The Carthaginian republic was a force to be reckoned with, controlling inconceivable amounts of wealth and land all around the Mediterranean.
However, just over a century later in 146 B.C., Carthage was burnt to the ground by the Romans. The destruction of Carthage was so thorough that many things are still not known about their civilization today. Carthage went from being a major power to literally being wiped off of the map.
A few decades after the annihilation of Carthage, it was Rome’s turn to become the world’s largest city for close to 500 years. Of course, Rome itself would fall by 476 A.D. for a variety of reasons.
And so the title of the world’s largest city would transfer again, this time to Constantinople across the Mediterranean.
The World’s Largest Cities Throughout History
In the grand scheme of history, things change quite fast. One cataclysmic choice or event can turn even the greatest empire into a heap of rubble. Sometimes the decline of a world-class city is more gradual – and it is over time that it loses its title to another place in a far and distant land.
The following animated map from KPMG Demographics tracks the world’s largest cities from 4,000 BC to today, and it shows how temporary a city’s rise to prominence can be.
(Keep in mind that there is some disagreement by historians over which cities were the biggest in certain time periods.)
The power of industrialization and technology can be seen here. Up until the 1800s, it was almost unfathomable to have a city of more than a million inhabitants.
Sanitation was a major limiting factor, but other issues like transportation and a lack of density also made it a challenge. The Industrial Revolution changed that, and starting in the 1800s you see cities like London, New York, and Tokyo taking the title in an exponential fashion. It caps off with Delhi in 2050, expected to have a whopping 40 million inhabitants by that time.
However, it’s worth seeing this urban growth through a different lens. Instead of looking at the biggest cities overall, the below map from Max Galka’s Metrocosm blog looks at the founding of major cities to show the progress of urbanization from 3700 B.C. until today.
You can use the sliding bar to adjust the date. The real fireworks begin in the year 1200, with an explosion in cities between 1800 and today.
Here’s one final look at cities and their modern populations, this time an interactive 3d globe also from Metrocosm:
This gives an idea of where the largest concentrations of people live today. The globe also puts into perspective a small subsection of Asia, which holds more of the world’s population within a small circle than outside of it.

Car Brand Loyalty in 2024
This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.
This graphic visualizes the best and worst car brands in terms of brand loyalty. This is measured by the % of current owners who would buy from the same brand for their next vehicle.
Data comes from Consumer Reports’ owner satisfaction survey, which includes responses from owners of more than 330,000 vehicles.
Car Brands With the Most Loyal Customers
Rivian takes the top spot in this ranking, with 86% of owners saying they would buy from the brand again. The EV startup has carved an interesting niche for itself with its outdoor adventure-focused models, and despite several recalls, appears to have won the hearts of its early customers.
Company | % who would buy again |
---|---|
🇺🇸 Rivian | 86 |
🇩🇪 Mini | 77 |
🇩🇪 BMW | 76 |
🇩🇪 Porsche | 76 |
🇺🇸 Tesla | 74 |
🇰🇷 Genesis | 73 |
🇯🇵 Lexus | 73 |
🇯🇵 Subaru | 70 |
It’s interesting to note that Tesla held the #1 spot in last year’s ranking.
Car Brands With the Least Loyal Customers
At the other end of the spectrum we have brands with the least loyal customers, suggesting that owners are less satisfied with their purchase.
Company | % who would buy again |
---|---|
🇺🇸 Cadillac | 61 |
🇺🇸 Chrysler | 60 |
🇩🇪 Mercedes-Benz | 59 |
🇩🇪 Audi | 59 |
🇺🇸 Jeep | 58 |
🇯🇵 Nissan | 55 |
🇩🇪 Volkswagen | 51 |
🇯🇵 Infiniti | 43 |
At the bottom of this table is Nissan’s luxury marque, Infiniti, with only 43% of owners saying they would revisit the brand for their next car.
Infiniti dealerships are aware of this alarming trend, and have attributed it to the brand’s aging lineup. In a recent interview, Steve Lapin, Chairman of the Infiniti National Dealer Advisory Board, said: “Product is king. Infiniti doesn’t have the right products right now to compete in the marketplace.”
