Visualizing the World’s Busiest Ports
The World’s Busiest Ports
An estimated 90% of world trade is facilitated by maritime shipping, and as trade volumes continue to increase, the world’s busiest ports continue to grow larger and more efficient to meet demand.
In fact, in just the last four years, the median annual volume of the top 50 ports jumped from 5.49 to 5.86 million twenty-foot equivalent units (TEUs).
Here are the world’s 20 largest ports, using the most recent data from the World Shipping Council:
Rank | Port Name | Country | 2016 Volume | 2012 Volume | 4-Year Change |
---|---|---|---|---|---|
1 | Shanghai | 🇨🇳 China | 37.1 | 32.5 | +14% |
2 | Singapore | 🇸🇬 Singapore | 30.9 | 31.7 | -2% |
3 | Shenzhen | 🇨🇳 China | 24.0 | 22.9 | +5% |
4 | Ningbo-Zhoushan | 🇨🇳 China | 21.6 | 16.8 | +28% |
5 | Busan | 🇰🇷 S. Korea | 19.9 | 17.0 | +17% |
6 | Hong Kong | 🇭🇰 China | 19.8 | 23.1 | -14% |
7 | Guangzhou Harbor | 🇨🇳 China | 18.9 | 14.7 | +28% |
8 | Qingdao | 🇨🇳 China | 18.0 | 14.5 | +24% |
9 | Jebel Ali | 🇦🇪 U.A.E. | 15.7 | 13.3 | +18% |
10 | Tianjin | 🇨🇳 China | 14.5 | 12.3 | +18% |
11 | Port Klang | 🇲🇾 Malaysia | 13.2 | 10.0 | +32% |
12 | Rotterdam | 🇳🇱 Netherlands | 12.4 | 11.9 | +4% |
13 | Kaohsiung | 🇹🇼 Taiwan | 10.5 | 9.8 | +7% |
14 | Antwerp | 🇧🇪 Belgium | 10.0 | 8.6 | +16% |
15 | Dalian | 🇨🇳 China | 9.6 | 8.9 | +8% |
16 | Xiamen | 🇨🇳 China | 9.6 | 7.2 | +34% |
17 | Hamburg | 🇩🇪 Germany | 8.91 | 8.89 | 0% |
18 | Los Angeles | 🇺🇸 U.S.A. | 8.9 | 8.1 | +10% |
19 | Tanjung Pelepas | 🇲🇾 Malaysia | 8.3 | 7.7 | +8% |
20 | Keihin | 🇯🇵 Japan | 7.6 | 7.9 | -3% |
Volume is measured in millions of TEUs
Only five of the top 20 ports in the world are now located outside of East Asia. The Port of Los Angeles is the only U.S. entrant in the top 20, and only three European ports made the cut.
Today, trade is more likely than ever to flow through the South China Sea.
Ruling the High Seas
From dollar store knick-knacks to nuclear reactor components, China’s manufacturing output is a critical link in the global supply chain. Getting all those products to consumers and companies around the world is big business, and over the past decade, China has emerged as the heavyweight champion of world shipping.
While Danish company, Maersk, is still the largest shipping line, an ever increasing share of the world’s container traffic is moving through Chinese controlled ports. An estimated two-thirds of container traffic now passes through Chinese ports or ports that have received Chinese investment.
New Kids on the Block
While shipping volumes on a global basis continue to rise, not all of that growth has been spread around equally. This is particularly true for established titans of the South China Sea.
At the outset of this millennium, Hong Kong and Singapore were home to the busiest ports in the world. Today, both are facing increased competition from neighboring ports, as well as declining volumes:
In contrast, the massive Port of Shanghai saw a 71% increase over the last decade, and many other Chinese ports has seen significant growth in volume in recent years.
If China’s One Belt One Road initiatives and investments in global port facilities are any indication, the country’s domination of maritime shipping will only continue to strengthen in the near term.
Maps
Mapped: All of the World’s Roads, by Continent
What does a road map of the world look like? Here’s a deep view of roads visualized by type across countries and continents.

Mapped: All of the World’s Roads, by Continent
Once upon a time, it was said that all roads led to Rome. Now with at least 21 million kilometers of roads spanning the globe, every continent and country has its own web of crisscrossing connections, from major highways to rural drives.
And there’s no better way to see the scale and spread of roads than by visualizing them. Adam Symington from PythonMaps used data from the Global Roads Inventory Project (GRIP) to map all the roads in the world, creating an accurate representation of humanity’s need to connect.
Creating the Global Road Map
The GRIP database pulled information from a variety of sources including governments, research institutes, NGOs, and crowd-sourcing initiatives to create a harmonized dataset of geospatial road information for a 2018 paper, “Global patterns of current and future road infrastructure.”
Researchers categorized roads into types using a UN classification system, which have been visualized in three colors on this map:
Category | Definition | Color |
---|---|---|
Main Roads | Highways + primary roads between and within cities and towns. Multi-lane, limited entry and exit points. | White |
Secondary Roads | Paved, high-traffic, access between neighborhoods | Yellow |
Tertiary Roads | Paved or unpaved residential access within neighborhoods, or rural points of interest. | Red |
Local Roads | All other smaller roads that don't fit above, and usually are not throughfare. | Red |
This classification allowed for examining relationships between road infrastructure, development, wealth, and population distribution.
Which Country has the Largest Road Map?
With nearly 3 million kilometers of motorways, the U.S. has the largest road network in the world, nearly double that of China (1.7 million km) and three times that of India (1 million km).

The small Pacific island country of Palau has the smallest road network in the database measuring 18 kilometers. However, many overseas territories of countries have even smaller networks, with Norfolk Island being the smallest in the dataset at 10 km.
That said, when breaking the road networks down by type, the rankings change significantly.
China muscles out the U.S. with nearly double the amount of main roads (highways + primary roads). Meanwhile, Japan and Canada climb into the top 10 by largest main road networks, while India drops down to #8.

In the database, 1.8 million km or more than 50% of the U.S.’s large road map is made up of smaller local roads, giving unparalleled access across almost the entire country. It also has the world’s most secondary roads, while Argentina, India, and Australia lead the rankings with the most tertiary roads.
Regional Differences Between Types of Roads
These different types of roads have a striking effect on the regional visualizations of road maps.
In North America, the U.S. and Canada have a white-yellow hue accounting for the large number of highways, primary, and secondary roads.
In Mexico, the map takes on a distinct red tint, since tertiary and local roads account for nearly two-thirds of the country’s road network.
Something similar occurs in Europe, where old Cold War divisions play out in white, yellow, and red. France, Germany, Italy, and the U.K. glow hot in a mix of white and yellow, while former Eastern Bloc countries simmer more in red.
GRIP found that main roads (highways + primary) are usually found in North America, Europe, and China, while the rest of the world has a greater percentage of secondary (yellow) and tertiary and local (red) roads.
However, one interesting sidebar is that the four countries with the greatest percentage of main roads are all from the Middle East.
Rank (#) | Country | Main Roads (% of All) |
---|---|---|
1 | Bahrain 🇧🇭 | 100% |
2 | Kuwait 🇰🇼 | 81% |
3 | Bhutan 🇧🇹 | 79% |
4 | Qatar 🇶🇦 | 62% |
5 | Suriname 🇸🇷 | 54% |
6 | U.A.E 🇦🇪 | 46% |
7 | Ireland 🇮🇪 | 44% |
8 | Singapore 🇸🇬 | 44% |
9 | Bosnia 🇧🇦 | 42% |
10 | Norway 🇳🇴 | 41% |
11 | China 🇨🇳 | 40% |
12 | Liechtenstein 🇱🇮 | 38% |
13 | Canada 🇨🇦 | 38% |
14 | Panama 🇵🇦 | 37% |
15 | Grenada 🇬🇩 | 34% |
While there may be reasons for this, it’s possible it could also be a quirk in the database, depending on how data is collected or classified in the region.
What Do Road Networks Tell Us About Countries?
Analysis of the GRIP database found that “total road length in a country is strongly and positively related to its total land surface area, human population density, gross domestic product, and OECD membership.”
However, of all the correlations, population density is perhaps the most visible in snapshots of the larger world map, such as in this one of Asia.
The Indian subcontinent and Eastern China are the two most populous regions of the world, accounting for nearly 35% of the world’s population. The most populous regions within—especially in China—have more roads, representing growing cities and urban centers.
The opposite is visible in Africa and Australia, where large natural features like deserts prevent human settlement and roads vanish from the visualization as well.
Road Maps and Sustainable Development
The environmental impact of economic development is also visual on these road networks.
Road construction leads to emissions and biodiversity displacement. By matching road maps with natural environment visualizations like this forest map, we can see how much of the world’s pristine natural reserves are still untouched by humankind.
In South America for example, the Amazon rainforest accounts for a large chunk of Brazil’s lacking road coverage.
Finally, though the GRIP research attributes population and affluence as key correlations with road development, other economic factors drive road network expansion as well.
The researchers estimate that there will be 4 million kilometers of additional roads covering the Earth by 2050, even under conservative assumptions.
In the never-ending balancing act of sustainable development and economic prosperity, development of the world’s road map will have ripple effects for years to come.
