Demographics of Paris

The city of Paris (also called the Commune or Department of Paris) had a population of 2,165,423 people within its administrative city limits as of January 1, 2019. It is surrounded by the Paris unité urbaine, or urban area, the most populous urban area in the European Union. In 2018 the unité urbaine had a population of 10,816,803 in 2854 km2. The Paris Region, or Île-de-France, covers 12012 km2, and has its own regional council and president. It has a population of 12,213,447 as of January 2018, or 18.3 percent of the population of France. The metropolitan or functional area (aire d'attraction) of Paris covers 18941 km2 and has 13,064,617 inhabitants (2018).

The population of the city of Paris reached a historic high of 2.9 million in 1921 but then declined; between 1954 and 1999 it declined at every census, falling to 2,125,246 in 1999. After that it began to climb again, reaching 2,240,621 in 2012, but falling to 2,187,526 in 2017.

The city's population loss reflected the experience of most other core cities in the developed world that have not expanded their boundaries. The principal factors in the process were a significant decline in household size, and a dramatic migration of residents to the suburbs between 1962 and 1975. Factors in the migration included deindustrialisation, high rent, the gentrification of many inner quarters, the transformation of living space into offices, and greater affluence among working families. The city's population loss was one of the most severe among international municipalities and the largest for any that had achieved more than 2,000,000 residents. Since then, an influx of younger residents and immigrants has contributed to the growth of the city.

Density
According to Eurostat, the EU statistical agency, in 2012 the Commune of Paris was the most densely populated city in the European Union, with 21,616 people per square kilometre within the city limits (the NUTS-3 statistical area), ahead of Inner London West, which had 10,374 persons per square kilometre. According to the same census, three departments bordering Paris, Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne, had population densities of over ten thousand persons per square kilometre, ranking among the ten most densely populated areas of the EU.

Paris is one of the most densely populated cities in the world. Its density, excluding the outlying woodland parks of Boulogne and Vincennes, was 24448 PD/km2 in the 1999 official census, which could be compared only with some Asian megapolises and the New York City borough of Manhattan. Even including the two woodland areas, its population density was 20755 PD/km2 in 2017, the sixth-most-densely populated commune in France after Levallois-Perret, Vincennes, Le Pré-Saint-Gervais, Saint-Mandé and Montrouge, all of which border the city proper.

The most sparsely populated quarters are the western and central office and administration-focused arrondissements. The city's population is densest in the northern and eastern arrondissements; the 11th arrondissement had a density of 40,672 PD/km2 in 1999, and some of the same arrondissement's eastern quarters had densities close to 100,000 /km2 in the same year.

Paris agglomeration
The city of Paris covers an area much smaller than the urban area of which it is the core. At present, Paris's real urbanisation, defined by the pôle urbain (urban cluster) statistical area, covers 2845 km2, or an area about 27 times larger than the city itself. The administration of Paris's urban growth is divided between itself and its surrounding departments: Paris's closest ring of three adjoining departments, or petite couronne ("small ring") are fully saturated with urban growth, and the ring of four departments outside of these, the grande couronne departments, are only covered in their inner regions by Paris's urbanisation. These eight departments form the larger administrative Île-de-France région; most of this region is filled, and overextended in places, by the Paris aire urbaine, which, in 2017, was populated by over 12 million people.

The Paris agglomeration has shown a steady rate of growth since the end of the late 16th century French Wars of Religion, save brief setbacks during the French Revolution and World War II. With an estimated total of 12.2 million inhabitants for 2017, the annual population growth rate of the Île-de-France région lied between 0.3% and 0.9% over the past 50 years.

Immigration
By law, French censuses do not ask questions regarding ethnicity or religion, but do gather information concerning one's country of birth. From this it is still possible to determine that Paris and its metropolitan area is one of the most multi-cultural in Europe: According to the 2011 census, 456,105 residents of the municipality of Paris, or 20.3 percent, and 2,117,901 residents of the Paris Region (Île-de-France), or 17.9 percent, were born outside France. At the 1999 census, 4.2% of the population in Paris metropolitan area were recent immigrants (people who had immigrated to France between 1990 and 1999), the majority from Asia and Africa. 37 % of all immigrants in France live in the Paris region.

The first wave of international migration to Paris started as early as 1820 with the arrivals of German peasants fleeing an agricultural crisis in their homeland. Several waves of immigration followed continually until today: Italians and central European Jews during the 19th century; Russians after the revolution of 1917 and Armenians fleeing genocide in the Ottoman Empire; colonial subjects during World War I and later; Poles between the two world wars; Spaniards, Italians, Portuguese, and North Africans from the 1950s to the 1970s; North African Jews after the independence of those countries; Africans and Asians since then.

The Paris metropolitan region or "aire urbaine" is estimated to be home to some 1.7 million Muslims, making up between 10–15 per cent of the area's population. However, without official data, the margin of error of these estimates is extremely high as it is based on one's country of birth (someone born in a Muslim country or born to a parent from a Muslim country is considered as a "potential Muslim"). According to the North American Jewish Data Bank, an estimated 310,000 Jews also live in Paris and the surrounding Île-de-France region, an area with a population of 11.7 million inhabitants. Paris has historically been a magnet for immigrants, hosting one of the largest concentrations of immigrants in Europe today.

Immigrants and their children in departments of Île-de-France (Paris Region)
Anch National Institute for Statistics and Economic Studies, responsible for the production and analysis of official statistics in France, 20 per cent of people living in the city of Paris are immigrants and 41.3 per cent of people under 20 have at least one immigrant parent. Among the young people under 18, 12.1 per cent are of Maghrebi origin, 9.9 per cent of Subsaharan African origin and 4.0 per cent of South European origin. In 2020-2021, about 6 million people, or 49% of the population of Paris, are either immigrants (21%) or have at least one immigrant parent (28%), these figures do not include French people born in Overseas France and their direct descendants.

(source: Insee, EAR 2006) Reading: 436 576 immigrants live in Paris, representing 20% of Parisians and 22.4% of immigrants in Île-de-France. 162 635 children under 20 with at least one immigrant parent live in Paris, representing 41.3 per cent of the total of children under 20 in Paris and 15.4 per cent of the total of children under 20 with at least one immigrant parent in Île-de-France.

Expatriates
As of 2005 many expatriates settle in the western portion of Paris. Western Paris is in close proximity to many international schools and the La Défense area.

Many international students living in Paris live in the large dormitory complex of Cité Université Internationale de Paris, located just on the edge of the city in the 14th arrondissement.

Africans
As of 2012 tens of thousands of people of African origins live in Paris. This group includes those born in France who had African parents and naturalized French citizens born in Africa. The majority come from the Maghreb, including Algeria, Morocco, and Tunisia. Other countries with populations in Paris include Burkina Faso, the Congo, Guinea, Mali, and Senegal.

Asians
As of 1998 Île-de-France has half of the Asian population of France. As of 1990 the majority of Asians living in France are ethnic Chinese originating from several countries.

In 1974 France stopped allowing foreign workers into its borders. The Asian population of France increased despite the closure. In 1975 there were 20,000 Asians in Île-de-France. In 1982 the region had 59,000. This increased to 108,000 in 1990.

In France the "Asians" are defined as people originating from the East Asian cultural sphere. The term does not include people from the Indian subcontinent. The usage of "Asians" differs from that of Anglo-Saxon countries.

Geography of the Asian population
For the entire Île-de-France region, there were a total of 108,511 persons who held or formerly held Cambodian, Chinese, Laotian, Taiwanese, and Vietnamese citizenships as of 1990.

As of 1990 fewer than 10,000 persons of East/Southeast Asian origin resided in six communes of Marne-la-Vallée. 26% of the population of Lognes was Asian, and other percentages were 8% in Noisiel, 5-6% in Noisy-le-Grand, and 5-6% in Torcy. In 1982 there were 6,000 Asians in Marne-la-Vallée, making up 3-4% of the area's population. In 1987 the number increased to 9,000.

Notes for the table:
 * until the 1830s, urbanization was contained within the administrative borders of the City of Paris; urban area figures before 1835 are thus the same as the city proper figures
 * the phenomenon of long commutes did not appear until the 1960s; metropolitan area figures before 1968 are thus essentially the same as the urban area figures
 * time comparisons should be exercised with care, as statistical borders vary year after year. E.g., the metropolitan area figure for 1968 is within the 1968 borders of the metropolitan area, whereas the metropolitan area figure for 1975 is within the 1975 expanded borders of the metropolitan area.
