(Redirected from Île de France)

The Île-de-France (/ˌl də ˈfrɒ̃s/, French: [il fʁɑ̃s] ; lit.'Island of 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.[1] Centred on the capital Paris, it is located in the north-central part of the country and often called the Paris Region[3] (French: Région parisienne, pronounced [ʁeʒjɔ̃ paʁizjɛn]). Île-de-France is densely populated and retains a prime economic position on the national stage, but it covers only 12,012 square kilometres (4,638 square miles), about 2% of metropolitan French territory. Its 2017 population was nearly one-fifth of the national total.[4]

NUTS RegionFR1

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,[5]: 12  and 5% of the European Union's.[5]: 12  It has the highest per capita GDP of any French region.[6]

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.[7]



Although the modern name Île-de-France literally means Island of France, its etymology is unclear. 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.[citation needed]

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.[8]

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.[10][11] 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.[12] The Parisii traded with many river towns (some as far away as the Iberian Peninsula) and minted their own coins for that purpose.[13]

The Romans conquered the area in 52 BC and began their settlement on Paris's Left Bank.[14] It became a prosperous city with a forum, baths, temples, theatres, and an amphitheatre.[15] 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 (Latin "Hill of Martyrs"), 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.[16]

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 (885–86). In 987, Hugh Capet, Count of Paris (comte de Paris) and Duke of the Franks (duc des Francs), was elected King of the Franks (roi des Francs). Under the rule of the Capetian kings, Paris gradually became the largest and most prosperous city in France.[16]

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 ("District of the Paris Region"). 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.



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.



Île-de-France has a land area of 12,011 km2 (4,637 sq mi). 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 ("small ring"); it extends into a second outer ring of four departments known as the grande couronne ("large ring"). 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, 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.[4]



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.[17]

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 (between 10 metres (33 ft) and 200 metres (660 ft)), 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.


Paris as an engine of the global economy: the skyscrapers of La Défense, the largest purpose-built business district of Europe, with 3.35 million m² (36 million sq. ft) of office space.[18]

Paris region (Île-de-France) produced €742 billion (Gross domestic product)[5] or around 1/3 of the economy of France in 2019.[5]: 12 

The regional economy has gradually shifted toward high-value-added service industries (finance, IT services, etc.) and high-tech manufacturing (electronics, optics, aerospace, etc.).[19] 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.[20]

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.[21]

Other major sectors of the regional economy include energy companies (Orano, Engie, Électricité de France, and Total S.A.). The two major French automobile manufacturers, Renault at Flins-sur-Seine and Groupe PSA at Poissy, do much of their assembly work outside of 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.[21]

The energy sector is also well established in the region. The nuclear power industry, with its major firm 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.



In 2018 just 7.2 percent of employees in the region were engaged in industry; 62.3 percent were engaged in commerce and market services; 25.5 percent in non-market services, including government, health and education; 4.8 percent in construction; and 0.2 percent in agriculture.[22]

The largest non-government employers in the region as of the end of 2015 were the airline Air France (40,657); the SNCF (French Railways, 31,955); the telecom firm Orange S.A. (31,497); the bank Société Générale (27,361); the automotive firm Groupe PSA (19,648); EDF (Electricité de France, 18,199); and Renault (18,136).[23] While the Petite Couronne, or departments closest to Paris, previously employed the most industrial workers, the largest number is now in the Grande Couronne, the outer departments.[22]

The unemployment rate in the region stood at 8.6% at the end of 2016. It varied within the region from 7.8 percent in the city of Paris, to a high of 12.7 percent in Seine-Saint-Denis, and 10 percent in Val-d'Oise; to regional lows of 7.4 percent in Yvelines; 7.5 percent in Hauts-de-Seine; 7.7 percent in Essonne; 7.9 percent in Seine et Marne, and 8.8 percent in Val de Marne.[24]



In 2018, 48 percent of the land of the Île-de-France was devoted to agriculture; 569,000 hectares were cultivated. The most important crops are grains (66 percent), followed by beets (7 percent), largely for industrial use, and grass for grazing. In 2014, 9,495 hectares were devoted to bio-agriculture. However, the number of persons employed in agriculture in the region dropped 33 percent between 2000 and 2015 to just 8,460 persons in 2015.[25]



The Île-de-France is one of the world's top tourist destinations, with a record 23.6 million hotel arrivals in 2017, and an estimated 50 million visitors in all types of accommodation. The largest number of visitors came from the United States, followed by England, Germany and China.[26] [27][28] The top tourist attraction in the region in 2017 was Disneyland Paris, which received 14.8 million visitors in 2017, followed by the Cathedral of Notre-Dame (est. 12 million) and the Basilica of Sacre-Coeur at Montmartre (est. 11.1 million visitors).[29]

Notable historic monuments in the Region outside of Paris include the Palace of Versailles (7,700,000 visitors), the Palace of Fontainebleau (500,000 visitors), the chateau of Vaux-le-Vicomte (300,000 visitors), and the Château de Malmaison, Napoleon's former country house; and the Basilica of Saint-Denis, where the Kings of France were interred before the French Revolution.[30]

Regional government and politics

Seat of the regional council of Île-de-France in Saint-Ouen-sur-Seine (2021)

The Regional Council is the legislative body of the region. Its seat is in Saint-Ouen-sur-Seine, at 2 rue Simone-Veil. On 15 December 2015, a list of candidates of the Union of the Right, a coalition of centrist and right-wing parties, led by Valérie Pécresse, narrowly won the regional election, defeating the Union of the Left, a coalition of socialists and ecologists. The socialists had governed the region for the preceding 17 years.

Since 2016 the regional council has 121 members from the Union of the Right, 66 from the Union of the Left and 22 from the far-right National Front.[31]

At the 2019 census, 75.1% of the inhabitants of Île-de-France were natives of Metropolitan France, 1.7% were born in Overseas France, and 23.1% were born in foreign countries.[36] A quarter of the immigrants living in the Île-de-France were born in Europe (38% of whom in Portugal), 29% were born in the Maghreb and 22% in the rest of Africa (in particular West and Central Africa), 3% were born in Turkey and 15% in the rest of Asia, 5% were born in the Americas (not counting those born in the French overseas departments in the Americas, who are not legally immigrants), and 0.1% in Oceania (not counting those born in the French territories of the South Pacific, who are not legally immigrants).[37]

In 2013, roughly 2,206,000 residents of the Île-de-France were immigrants, born outside of France. This amounted to 18.5% of the population of the region, twice the national average. Four out of ten immigrants living in France reside in the region. The immigrant population of the Île-de-France has a higher proportion of non-Europeans, as well as a higher proportion of immigrants with an advanced level of education, than the rest of France. The population of immigrants is more widely distributed throughout the region than it was in the early 2000s, but the concentrations remain high in certain areas, particularly Paris and the department of Seine-Saint-Denis. The proportion of residents born outside of Metropolitan France rose between the 1999 (19.7%) and 2019 censuses (24.9%).[38][36]

Petite Couronne

Map of the Petite Couronne with Paris
Locator map showing the municipalities in which the Petite Couronne is divided. Paris is divided into its 20 arrondissements.

The Petite Couronne[41] (literally "Little Crown" or inner ring) is formed by the three departments bordering Paris, forming a geographical crown around it. These departments, until 1968 part of the disbanded Seine department, are Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne. The most populated towns of the Petite Couronne are Boulogne-Billancourt, Montreuil, Saint-Denis, Nanterre and Créteil.

The Métropole du Grand Paris is an administrative structure that comprises Paris and the three departments of the Petite Couronne, plus seven additional communes in the Grande Couronne.
