Île-de-France
The Île-de-France is the most populous of the eighteen regions of France, with an official estimated population of 12,271,794 residents on 1 January 2023. Containing the capital city of France, Paris, it is located in the north-central part of the country and often called the Paris Region. Île-de-France is densely populated and retains a prime economic position on the national stage, and it covers, about 2% of metropolitan French territory. Its 2017 population was nearly one-fifth of the national total.
The region is made up of eight administrative departments: Paris, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Seine-et-Marne, Val-de-Marne, Val-d'Oise and Yvelines. It was created as the "District of the Paris Region" in 1961. In 1976, when its status was aligned with the French administrative regions created in 1972, it was renamed after the historic province of Île-de-France. Residents are sometimes referred to as Franciliens, an administrative word created in the 1980s. The GDP of the region in 2019 was nearly one-third of the French, and 5% of the European Union's. It has the highest per capita GDP of any French region.
Beyond the city limits of Paris, the region has many other important historic sites, including the palaces of Versailles and Fontainebleau, as well as the most-visited tourist attraction in France, Disneyland Paris. Although it is the richest French region, a significant number of residents live in poverty. The official poverty rate in the Île-de-France was 15.9% in 2015. The region has witnessed increasing income inequality in recent decades, and rising housing prices have pushed the less affluent outside Paris.
Etymology
Although the modern name Île-de-France literally means Island of France, its etymology is unclear. Despite its name, the region itself is not an island. The "island" may refer to the land between the rivers Oise, Marne and Seine, or it may also have been a reference to the Île de la Cité, where the French royal palace and cathedral were located.Alternatively, the name may refer to the lands that were under the direct rule of the Capetian kings during the Middle Ages; thus, the lands were an "island" in a sea of various feudal territories ruled by vassals of the king.

History
The Île-de-France was inhabited by the Parisii, a sub-tribe of the Celtic Senones, from around the middle of the 3rd-century BC. One of the area's major north–south trade routes crossed the Seine on the île de la Cité; the meeting place of land and water trade routes gradually became an important trading centre. The Parisii traded with many river towns and minted their own coins for that purpose.The Romans conquered the area in 52 BC and began their settlement on Paris's Left Bank. It became a prosperous city with a forum, baths, temples, theatres, and an amphitheatre. Christianity was introduced in the middle of the 3rd century AD by Saint Denis, the first Bishop of Paris. According to legend, when Denis refused to renounce his faith before Roman authorities, he was beheaded on the hill that became known as Mons Martyrum, later "Montmartre". The legend further states that Denis walked headless from this hill to the north of the city. The place that he finally fell and was buried became an important religious shrine, the Basilica of Saint-Denis.
Clovis the Frank, the first king of the Merovingian dynasty, made the city his capital in 508. As the Frankish domination of Gaul began, there was a gradual immigration by the Franks to Paris and the Parisian Francien dialects were born. Fortification of the Île de la Cité failed to avert sacking by Vikings in 845, but Paris's strategic importance—with its bridges preventing ships from passing—was established by successful defence in the Siege of Paris. In 987, Hugh Capet, Count of Paris and Duke of the Franks, was elected King of the Franks. Under the rule of the Capetian kings, Paris gradually became the largest and most prosperous city in France.
The Kings of France enjoyed getting away from Paris and hunting in the game-filled forests of the region. They built palatial hunting lodges, most notably Palace of Fontainebleau and the Palace of Versailles. From the time of Louis XIV to the French Revolution, Versailles was the official residence of the Kings and the seat of the French government. Île-de-France became the term used for the territory of Paris and the surrounding province, which was administered directly by the King.
During the French Revolution, the royal provinces were abolished and divided into departments, and the city and region were governed directly by the national government. After World War II, as Paris faced a major housing shortage, hundreds of massive apartment blocks for low-income residents were built around the edges of Paris. In the 1950s and the 1960s, thousands of immigrants settled in the communes bordering the city. In 1959, under President Charles De Gaulle, a new region was created out of six departments, which corresponded approximately with the historic region, with the name District de la région de Paris. On 6 May 1976, as part of the process of regionalisation, the district was reconstituted with increased administrative and political powers and renamed the Île-de-France region.
Geography
Île-de-France is in the north of France, neighboring Hauts-de-France to the north, Grand Est to the east, Bourgogne-Franche-Comté to the southeast, Centre-Val-de-Loire to the southwest, and Normandy to the west.Departments
Île-de-France has a land area of. It is composed of eight departments centred on its innermost department and capital, Paris. Around the department and municipality of Paris, urbanisation fills a first concentric ring of three departments commonly known as the petite couronne ; it extends into a second outer ring of four departments known as the grande couronne. The former department of Seine, abolished in 1968, included the city proper and parts of the petite couronne.The petite couronne consists of the departments of Hauts-de-Seine, Paris, Seine-Saint-Denis and Val-de-Marne; the grande couronne consists of those of Seine-et-Marne, Yvelines, Essonne and Val-d'Oise. Politically, the region is divided into 8 departments, 25 arrondissements, 155 cantons and 1,276 communes, out of the total of 35,416 in metropolitan France.
Topography
The outer parts of the Île-de-France remain largely rural. Agricultural land, forest and natural spaces occupy 78.9 percent of the region, and 28 percent of the region's land is in urban use.The River Seine flows through the middle of the region, which is crisscrossed by its tributaries and sub-tributaries, including the Rivers Marne, Oise and Epte. The River Eure does not cross the region but receives water from several rivers in the Île-de-France, including the Drouette and the Vesgre. The major rivers are navigable, and, because of the modest variations of altitude in the region, they have a tendency to meander and curve. They also create many lakes and ponds, some of which have been transformed into recreation areas, including Moisson-Mousseaux, Cergy-Neuville and Villeneuve-Saint-Georges.
Economy
Île-de-France produced €742 billion or around 1/3 of the economy of France in 2019. The regional economy has gradually shifted toward high-value-added service industries and high-tech manufacturing. In 2014, industry represented just under five percent of active enterprises in the region, and 10.2 percent of salaried workers. Commerce and services account for 84 percent of the business establishments in the region, and have 83.3 percent of the salaried employees. Financial services and insurance are important sectors of the regional economy; the major French banks and insurance companies, including BNP Paribas, Société Générale and Crédit Agricole, all have their headquarters in the region. The region also hosts the headquarters of the top French telecom companies and utilities, including Orange S.A., Veolia and EDF. The French stock market, the Bourse de Paris, now known as Euronext Paris, occupies a historical building in the center of Paris and is ranked fourth among global stock markets, after New York, Tokyo and London. Other major sectors of the regional economy include energy companies. The two major French automobile manufacturers, Renault, in Flins-sur-Seine, and Groupe PSA, in Poissy, do much of their assembly work outside France but still have research centre and large plants in the region. The leading French and European aerospace and defense companies, including Airbus, Thales Group, Dassault Aviation, Safran Aircraft Engines, the European Space Agency, Alcatel-Lucent, and Arianespace, have a large presence in the region.The region is served by Charles de Gaulle Airport. The airport is also the hub of Air France. In 2024, the airport handled 70,290,260 passengers and 466,543 aircraft movements, making it the world's fourteenth busiest airport and Europe's third busiest airport in terms of passenger numbers. Charles de Gaulle is the busiest airport within the European Union. In terms of cargo traffic, the airport is the second busiest in Europe, after Frankfurt, handling 1,914,681 tonnes of cargo in 2024. As of 2025, it was the airport served by the second highest number of airlines, after Suvarnabhumi Airport, with 105 airlines operating from it. Orly Airport also remains the busiest French airport for domestic traffic and the second busiest French airport overall in passenger traffic, with 33,123,027 passengers in 2024.
The energy sector is also well established in the region. The nuclear power industry, with its major firm being Orano, has its headquarters in Île-de-France, as does the main French oil company Total S.A., the top French company in the Fortune Global 500, and the main electric utility, Électricité de France. The energy firm Engie also has its main offices in the region at La Défense.
