Before a megaproject gets the nod to go ahead, a very unique set of circumstances must first be considered.
There is no blueprint or shortcut for building a world-changing megaproject. In fact, each one must be designed and built from the ground up, often amidst considerable amounts of red tape and criticism. Builders of megaprojects embrace the unknown, even when faced with incredible amounts of risk and massive cost overruns.
At the same time, successful megaprojects can accomplish things that have never been done before. They can be pinnacles of human achievement, and spectacles such as the International Space Station and the U.S. Interstate Highway System have already changed the world.
The World’s Largest Megaprojects
This infographic from Futurism details nine of the world’s largest megaprojects currently in construction.
They range from giant $64 billion theme parks (Dubailand) to massive canals that will take 48 years to build (South-North Water Transfer Project in China).
Here are the nine largest megaprojects in construction right now, in order from most to least expensive:
1. International Space Station – $150 billion (as of 2010)
The most expensive single item ever built. Expansions beyond 2020 are estimated to eventually cost $1 trillion.
2. Al Maktoum International Airport – $82 billion
This airport in Dubai will be fully operational by 2018. It will be the world’s largest in terms of size and passenger volume – so big that four jets will be able to land simultaneously.
3. South-to-North Water Transfer Project – $78 billion (as of 2014)
Thought the Three Gorges Dam was massive? This other Chinese megaproject is already nearly three times as expensive – it aims to divert water from the Yangtze River using three huge canals to bring it to the north of the country.
4. California High-Speed Rail – $70 billion
Spanning 1,300 km (808 mi), this will link San Francisco to Los Angeles.
5. Dubailand – $64 billion
This mega theme park project will open in 2025 in Dubai. It will also have the world’s largest hotel (6,500 rooms), sports venues, eco-tourism, science attractions, and a giant mall.
6. London Crossrail Project – $23 billion
London is expanding its underground system, with 42 km (26 mi) of new tunnels to connect 40 stations. Everything will be complete by 2020.
7. Beijing Daxing International Airport – $13 billion
Opening in 2025, this airport megaproject will have seven runways and the largest terminal in the world. It will help ease the load on nearby Beijing Capital International Airport.
8. Jubail II – $11 billion
The second phase of development of the Jubail Industrial City in Saudi Arabia will add 100 industrial plants, an oil refinery, and one of the bigger desalination plants in the world.
9. Hong Kong-Zhuhai-Macao Bridge – $10.6 billion
A series of bridges and undersea tunnels to link the three major cities on the Pearl River Delta in China. Ultimately, it will be 50 km (31 mi) of links, opening sometime beyond 2021.

With a few notable exceptions, the world is rapidly aging.
Today’s infographic, which was shared by Bill Gates on Reddit, shows this incredible explosion in age and how different countries contrast with one another on this demographic metric.
While aging populations in Europe, North America, and Asia stand out on this type of visualization, it’s also important to look at the negative space. In both South America and Africa, populations are still quite young, with Africa getting younger and younger.
Note: The infographic is grouped based on U.N. regional classifications, and lumps Central America, the Caribbean, and South America as one demographic region.
The Oldest Countries
Which countries are the outliers in terms of global demographics?
Let’s start by taking a look at the oldest countries in terms of median age.
|#2 (t)||Germany||45 years||Europe|
|#2 (t)||Italy||45 years||Europe|
|#4 (t)||Greece||44 years||Europe|
|#4 (t)||Bulgaria||44 years||Europe|
|#4 (t)||Portugal||44 years||Europe|
Japan takes the cake for the oldest population and it’s joined by a host of European nations.
The following countries tied for the #7 spot, which is just off of the above list: Austria, Croatia, Latvia, Lithuania, Slovenia, Spain, and Bermuda. All of these places had median ages of 43 years, with Bermuda being the only non-European state of this group.
It’s worth noting that some smaller countries appear to be excluded from Gates’ infographic. As we showed on our last chart covering the subject of median age, which uses a different data set, the small city-state of Monaco (which has a population of just 39,000 people) actually has the highest median age in the world at 53.1 years.
The Youngest Countries
Now, let’s take a peek at the world’s youngest countries in terms of median age.
|#1 (t)||Chad||14 years||Africa|
|#1 (t)||Niger||14 years||Africa|
|#3 (t)||Afghanistan||16 years||Middle East|
|#3 (t)||Angola||16 years||Africa|
|#3 (t)||Burkina Faso||16 years||Africa|
|#3 (t)||Mali||16 years||Africa|
|#3 (t)||Somalia||16 years||Africa|
|#3 (t)||South Sudan||16 years||Africa|
|#3 (t)||Uganda||16 years||Africa|
The youngest countries globally are Chad and Niger with a median population age of 14 years. Both are located in Sub-Saharan Africa.
The only non-African country is war-torn Afghanistan, where the median age is 16 years.
A variety of countries tied with a median age of 17 years old, which puts them just off of the above list. Those countries include: Benin, Burundi, Ethiopia, Madagascar, Malawi, Nigeria, Tanzania, Zambia, Yemen, and Timor-Leste.
More Context on Aging

To get a sense of change over the coming decades, it’s worth taking a look at this animation that shows median age projections with a focus on Western countries all the way until the year 2060.
Map: Visualizing 40 Years of Nautical Piracy
Ever since humans first sailed the high seas, piracy has been a dangerous risk. See instances of modern piracy on this detailed map.

For millennia, voyaging on the open seas has been a dangerous and risky endeavor.
Between the powerful forces of Mother Nature and self-made obstacles stemming from human error, there is no shortage of possible calamities for even the bravest of sailors.
But for most of human history, perhaps the biggest fear that sailors grappled with was that of piracy. A run in with such marauders could lead to the theft of valuable cargo or even possible death, and it’s a threat that carries on even through modern times.
Hotbeds of Modern Piracy
Today’s map comes from Adventures in Mapping and it aggregates instances of piracy over the last 40 years based on the database from the National Geospatial-Intelligence Agency.
It should be noted that all individual events can be seen on this interactive map, which is what we will use to look at current hotbeds of piracy in more depth below.
1. The Strait of Malacca
The Strait of Malacca is one of the world’s most important shipping lanes, and also one of the most notorious.
A key chokepoint that sits between Malaysia and Indonesia, the Strait of Malacca is as narrow as 25 miles wide while also seeing a quarter of the world’s traded goods shipped through it every year. As a result, the strait and surrounding area are a frequent target for modern piracy.
Example account: (September 2002)
“The 1,699-ton Malaysian-flag tanker (NAUTICA KLUANG) was hijacked 28 Sep at 0300 local time while underway off Indonesia in the vicinity of Pulau Iyu Kecil at the southern tip of the Strait of Malacca. The pirates, armed with guns and machetes, tied up the crew and locked them in cabins. When the crew freed themselves at 0900, 29 Sep, the thieves had transferred the ship’s cargo of 3,000 tons of diesel oil, damaged communications equipment, and renamed it (CAKLU). “
2. The Horn of Africa
When many people think of modern piracy, they think of the coast of Somalia. While those waters are often avoided, the nearby areas can be just as problematic.
In particular, the Bab el Mandeb strait, which connects the Red Sea to the Indian Ocean, is a target for modern piracy. Similarly, the waters just off of Yemen are quite treacherous as well.
Example account: (January 1991)
“Somali pirates attached MV Naviluck off Somalia, killing three Filipino crewmen and setting fire to the vessel. Three boatloads of armed Somali pirates boarded the vessel on 12 Jan 91 took the crew ashore and killed three of them. The captain said the vessel was attacked off Xaafuun while on her way from Mombasa to Jeddah. He declined to specify the cargo. The surviving crew were made to jump overboard, and were later rescued by M Stern TRLR Dubai Dolphin.”
3. The Gulf of Guinea
While we hear the most about Somalian pirates, the Gulf of Guinea that sits south of Nigeria, Benin, Togo, and Ghana in West Africa is also a well-known hotbed.
Tanker theft of petroleum products being shipped to and from Nigerian refineries is rampant, creating an ongoing concern for companies operating in the region.
Example account: (June 2013)
“On 13 June, the Singapore-flagged underway offshore supply vessel MDPL CONTINENTAL ONE was boarded and personnel kidnapped at 04-02N 008-02E, approximately 7 nm southwest of the OFON Oil Field. Two fiberglass speedboats, each with 2 outboards engines, each carrying 14 gunmen in wearing casual t-shirts and no masks, launched an attack. The pirates were armed with AK47’s. After stealing personal items and belongings, four expat crew were kidnapped (Polish Chief Engineer) and three Indians (Captain, Chief Officer, and Bosun).”
4. The Caribbean
The Caribbean has a longstanding history with piracy – and while things have died down considerably since the peak, there are still isolated incidents that occur, especially with yachts.
Most incidents happen off the coast of Venezuela, or in and around the islands on the eastern side of the sea, such as Trinidad & Tobago, Barbados, and Grenada.
Example account: (March 2016)
“On 4 March, near position 13-16N 061-16W, several gunmen boarded a yacht anchored at Wallilabou in southwestern St. Vincent. During the course of the boarding, a German citizen aboard the yacht was killed and another person was injured. Authorities are investigating the incident.”
