Unless you’re a historian or map buff, interpreting a map of the Roman Empire can be a daunting exercise. Place names are unfamiliar and roads meander across the landscape making it difficult to see the connections between specific cities and towns.
Today’s visualization, by Sasha Trubetskoy, has mashed-up two enduring obsessions – transit maps and Ancient Rome – to help us understand the connection between Rome and its sprawling empire.
At the height of the Roman Empire, there were approximately 250,000 miles (400,000 km) of roads, stretching from Northern England to Egypt and beyond. This impressive network is what allowed Rome to exercise control and communicate effectively over such a large territory.
For a detailed look at travel times and costs, check out Stanford’s amazing ORBIS platform. The screenshot below shows the fastest, cheapest, and shortest routes between the settlement of Lutetia (the predecessor of present-day Paris) and Roma.
There were three main types of roads in Ancient Rome:
Viae publicae: Public highways or main roads, typically maintained by the military. These were the main, paved arteries of the empire and often included infrastructure such as drainage, milestones, and way stations.
Viae privatae: Private or country roads were financed by wealthy individuals to connect towns and other noteworthy points to the viae publicae.
Viae vicinales: These tertiary (often dirt) roads connected villages and areas within districts, eventually linking to the larger network.
This network of roads was vital as it allowed for quick troop movement as well as the development of a mail system. As the first major road network in Europe, the Romans quite literally laid the foundation for development across the continent.
There’s something alluring about Rome’s ability to carve out such a huge and advanced empire, with a legacy that lasts today.

The Enduring Influence of Roman Roads
London, Paris, Barcelona, and countless other major cities sprang from Roman settlements along the road network, and even as Europe descended into the Dark Ages (476-800 CE), Roman roads remained as one of few functioning modes of movement and communication. A recent study even points out that proximity to that foundational network of roads even has a strong correlation with economic activity today.
Beyond mere curiosity or entertainment, looking back at Roman ingenuity allows us to see the impact their road network had on today’s world. That enduring influence is one of the reasons ancient Rome still fascinates us to this day.

Mapped: The World’s Biggest Oil Discoveries Since 1868
Since 1868, there had been 1,232 oil discoveries over 500 million barrels of oil. This map plots these discoveries to reveal global energy hot spots.
Mapped: The World’s Biggest Oil Discoveries Since 1868
Oil and gas discoveries excite markets and nations with the prospect of profits, tax revenues, and jobs. However, geological processes did not distribute them equally throughout the Earth’s crust and their mere presence does not guarantee a windfall for whatever nation under which they lie.
Entire economies and nations have been built on the discovery and exploitation of oil and gas, while some nations have misused this wealth─or projected growth just never materialized.
The 20 Biggest Oil Discoveries
This map includes 1,232 discoveries of recoverable reserves over 500 million barrels of oil equivalent (BOE) From 1868 to 2010.
The discoveries cluster in certain parts of the world, covering 46 countries, and are of significant magnitude for each country’s economy. The average discovery is worth 1.4% of a country’s GDP today, based on the cash value from their production or net present value (NPV).
Of the total 1,232 discoveries, these are the 20 largest oil and gas fields:
|Field||Onshore/Offshore||Location||Discovery||Production start||Recoverable oil, past and future (billion barrels)|
|Ghawar Field||Onshore||Saudi Arabia||1948||1951||88-104|
|Mesopotamian Foredeep Basin||Onshore||Kuwait||n/a||n/a||66-72|
|Bolivar Coastal Field||Onshore||Venezuela||1917||1922||30-32|
|Safaniya Field||Offshore||Kuwait/Saudi Arabia||1951||1957||30|
|Upper Zakum Field||Offshore||Abu Dhabi, UAE||1963||1967||21|
|Romashkino Field||Onshore||Russia Volga-Ural||1948||1949||16-17|
|Shaybah Field||Onshore||Saudi Arabia||1998||1998||15|
|West Qurna Field||Onshore||Iraq||1973||2012||15-21|
Russia, West Siberia
The location of these deposits reveals a certain pattern to geopolitical flashpoints and their importance to the global economy.
While these discoveries have brought immense advantages in the form of cheap fuel and massive revenues, they have also altered and challenged how nations govern their natural wealth.
The Future of Resource Wealth: A Curse or a Blessing?
A ‘presource curse’ could follow in the wake of the discovery, whereby predictions of projected growth and feelings of euphoria turn into disappointment.
An oil discovery can impose detrimental consequences on an economy long before a single barrel leaves the ground. Ideally, a discovery should increase the economic output of a country that claims the oil. However, after major discoveries, the projected growth sometimes does not always materialize as predicted.
Getting from discovery to sustained prosperity depends on a number of steps. Countries must secure investment to develop a project to production, and government policy must respond by preparing the economy for an inflow of investment and foreign currency. However, this is a challenging prospect, as the appetite for these massive projects appears to be waning.
In a world working towards reducing its dependence on fossil fuels, what will happen to countries that depend on oil wealth when demand begins to dwindle?
Countries can no longer assume their oil and gas resources will translate into reliable wealth — instead, it is how you manage what you have now that counts.
Mapped: Top Countries by Tourist Spending
How much do your vacations contribute to your destination of choice? This visualization shows the countries that receive the most tourist spending.
Mapped: Top Countries by Tourist Spending
Many people spend their days looking forward to their next getaway. But do you know exactly how much these vacation plans contribute economically to your chosen destination?
Today’s visualization from HowMuch.net highlights the countries in which tourists spend the most money. Locations have been resized based on spending amounts, which come from the latest data from the World Tourism Organization (UNWTO).
Oh, The Places Tourists Will Go
Across the different regions, Europe’s combined tourist spending dominates at $570 billion. Easy access to closely-located countries, both via rail networks and a shared currency, may be a reason why almost 710 million visitors toured the region in 2018.
Asia-Pacific, which includes Australia and numerous smaller islands, saw the greatest growth in tourism expenditures. Total spending reached $435 billion in 2018—a 7% year-over-year increase, from 348 million visitors. Not surprisingly, some areas such as Macao (SAR) tend to rely heavily on tourists as a primary economic driver.
Here’s how other continental regions fared, in terms of tourist spending and visitors:
Total expenditures: $333 billion
Total visitors: 216 million
Expenses per visitor: $1,542
- Middle East
Total expenditures: $73 billion
Total visitors: 60 million
Expenses per visitor: $1,216
Total expenditures: $38 billion
Total visitors: 67 million
Expenses per visitor: $567
Of course, these numbers only paint a rudimentary picture of global tourism, as they vary greatly even within these regions. Let’s look closer at the individual country data for 2018, compared to previous years.
The Top Tourist Hotspots, By Country
It seems that many tourists are gravitating towards the same destinations, as evidenced by both the number of arrivals and overall expenditures for 2017 and 2018 alike.
|Country||2018 Spending||2018 Arrivals||Country||2017 Spending||2017 Arrivals|
|1. U.S. 🇺🇸||$214.5B||79.6M||1. U.S. 🇺🇸||$210.7B||74.8M|
|2. Spain 🇪🇸||$73.8B||82.8M||2. Spain 🇪🇸||$68B||81.8M|
|2. France 🇫🇷||$67.4B||89.4M||3. France 🇫🇷||$60.7B||86.9M|
|4. Thailand 🇹🇭||$63B||38.3M||4. Thailand 🇹🇭||$57.5B||35.4M|
|5. UK 🇬🇧||$51.9B||36.3M||5. UK 🇬🇧||51.2B||37.7M|
|6. Italy 🇮🇹||$49.3B||62.1M||6. Italy 🇮🇹||$44.2B||58.3M|
|7. Australia 🇦🇺||$45B||9.2M||7. Australia 🇦🇺||$41.7B||8.8M|
|8. Germany 🇩🇪||$43B||38.9M||8. Germany 🇩🇪||$39.8B||37.5M|
|9. Japan 🇯🇵||$41.1B||31.2M||9. Macao (SAR) 🇲🇴||$35.6B||17M|
|10. China 🇨🇳||$40.4B||62.9M||10. Japan 🇯🇵||$34.1B||28.6M|

Note that data is for international tourism only and does not include domestic tourism.
The top contenders have remained fairly consistent, as each country brings something unique to the table—from natural wonders to historic and man-made structures.
Where Highest-Spending Tourists Come From
The nationality of tourists also seems to be a factor in these total expenditures. Chinese tourists spent $277 billion internationally in 2018, likely thanks to the increasing consumption of an emerging, affluent middle class.
Interestingly, this amount is almost twice the combined $144 billion that American tourists spent overseas in the same year.
