Three Gorges Dam
EnergyThe world's largest hydropower station by installed capacity, at 22.5 GW, and the main flood-control structure on the Yangtze.
Although sighted by Christopher COLUMBUS in 1493 and claimed for Spain, it was the Dutch who occupied the island in 1631 and set about exploiting its salt deposits. The Spanish retook the island in 1633, but continued to be harassed by the Dutch. The Spanish finally relinquished Saint Martin to the French and Dutch, who divided it between themselves in 1648. Friction between the two sides caused the border to frequently fluctuate over the next two centuries, with the French eventually holding the greater portion of the island (about 57%). The cultivation of sugar cane introduced African slavery to the island in the late 18th century; the practice was not abolished until 1848. The island became a free port in 1939; …
The National Infrastructure Index maps the physical assets national life runs on — power stations and grids, water systems, ports, railways and airports, data networks, payment systems and launch sites. Each asset is placed in a Strategic Infrastructure capability group, so it can be read against the ratings in the National Capability index above.
Assets are chosen for how much of the economy and state depends on them and how hard they would be to replace. Each card records what the asset is, the category it belongs to, what it does and where it is.
Example assets. These twenty cards are modelled on China's most critical infrastructure and show on every nation page until each nation's own assets are mapped.

The National Development Index tracks the events that move a nation's capability — policy decisions, technological milestones, economic turns and external shocks — and places each one on the record with the date it happened and what followed from it. It is the narrative counterpart to the indices: where a rating says where Saint Martin stands, the index says how it arrived there.
Recent developments cover the current cycle, close enough that their consequences are still unfolding. Historical developments are the inflection points behind the present position — the decisions and events a reader needs in order to read the ratings above in context.
Archaeological evidence indicates human occupation of the island from around 2000 BC by Archaic Age hunter-gatherer communities. This marks the beginning of continuous human presence on Saint Martin.
Saladoid migrants reached the island around 550 BC from the Orinoco River basin, bringing agriculture and ceramic technology. They established villages such as Hope Estate, which remained occupied until roughly 650 AD.
Around 1300–1400 AD the Kalinago reached Saint Martin and began to displace the resident Arawak population. This reordered the island's indigenous society shortly before European contact.
Columbus sighted the island on his second voyage in November 1493 and claimed it for Spain, though Spain never effectively settled it. He anchored off the island now called Nevis on 11 November 1493, the feast day of Saint Martin of Tours, and named it accordingly; confusion among the poorly charted Leeward Islands later transferred the name to the island now known as Saint Martin.
In 1631 the Dutch occupied and fortified the island with Fort Amsterdam, and the Dutch West India Company began extracting salt from the pans, giving the nominally Spanish island its first sustained European economic function. The Spanish retook the island in 1633 but continued to be harassed by the Dutch before finally withdrawing.
With the Eighty Years' War underway, Spanish forces seized the island in 1633 and drove off the Dutch settlers. A Dutch attempt at recovery under Peter Stuyvesant in 1644 failed.
Spain relinquished the strategically devalued island after the Eighty Years' War ended in 1648, and Dutch and French settlers returned. Rather than fight, the two powers agreed to divide the island by the Treaty of Concordia, with Robert de Longvilliers becoming the first governor of French Saint Martin. Friction caused the border to fluctuate over the following two centuries, settling in its present position by 1817, with the French eventually holding the greater portion, about 57 per cent.
During the 18th century plantation agriculture expanded on both sides of the island, driving the importation of large numbers of enslaved Africans who came to outnumber European settlers. This established the demographic and economic foundations of modern Saint Martin.
In 1763 Saint Martin was administratively attached to France's Guadeloupe colony. This subordinate status shaped the territory's governance for more than two centuries.
Slavery was abolished on the French side on 28 May 1848 following a decree of the provisional government, an event commemorated locally on Schoelcher Day. The measure had immediate effects across the border: the entire enslaved population of the Dutch Diamond Estate Plantation fled to the French side and was recognised as free. The Dutch side abolished slavery only on 1 July 1863.
Duty-free status granted in 1939 laid the foundations for the island's later commercial and tourist growth.
After decades of economic decline and emigration in the early 20th century, wartime American construction of an airstrip improved the island's fortunes. The facility laid infrastructure groundwork for later air-borne tourism.
In 1946 Saint Martin, together with Saint Barthélemy, was incorporated as an arrondissement into the Guadeloupe département. This integrated the territory into the French departmental structure.
In 2025 just 12% of pupils began high school with adequate command of French, in a territory where Haitian Creole and other languages are widely used. The deficit is cited as an explanation for the unusually high drop-out rate.
The January 2021 census counted 31,477 inhabitants, a density of 592 per square kilometre, down from 35,334 in 2017. The decline is attributed chiefly to Hurricane Irma; the population had been only 8,072 at the 1982 census.
Irma struck on 6 September 2017, wrecking most of the French side's infrastructure and provoking looting that led France to deploy 240 gendarmes. Much of the territory's infrastructure was restored by March 2018, but the population fell from 35,334 in 2017 to 31,477 in 2021 as a result.
INSEE put Saint Martin's 2014 nominal GDP at 581.8 million euros, or 16,572 euros per head. That was half the GDP per capita of metropolitan France and 79% of Guadeloupe's, and well below Sint Maarten's US$33,536.
In 2010 the southern part of the island became Sint Maarten, a self-governing country within the Kingdom of the Netherlands, upon the dissolution of the Netherlands Antilles.
Fleming, the inaugural President, stepped down on 25 July 2008 after the Conseil d'État sanctioned him for one year over irregularities in his 2007 election campaign. His election was later declared invalid on 10 April 2009, with Daniel Gibbs appointed Acting President on 14 April 2009 and Gumbs re-elected on 5 May 2009.
Previously coded as GP under Guadeloupe, Saint Martin was assigned distinct international codes in October 2007. The change gave the collectivity separate statistical and administrative identity internationally.
The new status took effect on 15 July 2007 with the first session of the Territorial Council, following local assembly elections concluded that day. Saint Martin gained its own executive and legislative institutions while remaining an outermost region of the European Union and part of the eurozone.
On 9 February 2007 Parliament approved COM status for the French part of Saint Martin and, separately, for Saint Barthélemy. The law provided the legal basis for detaching the territory from Guadeloupe.
In 2003 residents of the French side voted in favour of leaving Guadeloupe to form a separate overseas collectivity of France. The referendum set in motion the constitutional change enacted in 2007.
Hurricane Luis hit Saint Martin in 1995, inflicting extensive damage and killing twelve people. It underlined the territory's exposure to Atlantic hurricanes.
Tourism grew rapidly during the 1970s and 1980s to become the mainstay of the island's economy.
Although sighted by Christopher COLUMBUS in 1493 and claimed for Spain, it was the Dutch who occupied the island in 1631 and set about exploiting its salt deposits. The Spanish retook the island in 1633, but continued to be harassed by the Dutch. The Spanish finally relinquished Saint Martin to the French and Dutch, who divided it between themselves in 1648. Friction between the two sides caused the border to frequently fluctuate over the next two centuries, with the French eventually holding the greater portion of the island (about 57%). The cultivation of sugar cane introduced African slavery to the island in the late 18th century; the practice was not abolished until 1848. The island became a free port in 1939; the tourism industry was dramatically expanded during the 1970s and 1980s. In 2003, the populace of Saint Martin voted to secede from Guadeloupe and in 2007, the northern portion of the island became a French overseas collectivity. In 2010, the southern Dutch portion of the island became the independent nation of Sint Maarten within the Kingdom of the Netherlands.

The economy of Saint Martin centers around tourism with 85% of the labor force engaged in this sector. Over one million visitors come to the island each year with most arriving through the Princess Juliana International Airport in Sint Maarten. No significant agriculture and limited local fishing means that almost all food must be imported. Energy resources and manufactured goods are also imported, primarily from Mexico and the United States. Saint Martin is reported to have the highest per capita income in the Caribbean.
