Through Paris, Asia and Africa

In 2023 the unité urbaine had a population of 11,013,774 in 2,824 km2 (1,090 sq mi). The Paris Region, or Île-de-France, covers 12,012 km2 (4,638 sq mi), and has its own regional council and president. It has a population of 12,463,067 as of January 2023, or 18.3 percent of the population of France. The metropolitan or functional area (aire d'attraction) of Paris covers 18,941 km2 (7,313 sq mi) and has 13,320,752 inhabitants (2023).

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 2,103,778 in 2023.

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 24,448 inhabitants per square kilometre (63,320/sq mi) 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 20,755/km2 (53,760/sq mi) 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 inhabitants per square kilometre (105,340/sq mi) in 1999, and some of the same arrondissement's eastern quarters had densities close to 100,000/km2 (260,000/sq mi) in the same year.

Notes: Without the Bois de Boulogne and the Bois de Vincennes.
