As a result, the April 2025 census recorded a marked population decline for Nouméa, with only 173,814 inhabitants living in the metropolitan area of Greater Nouméa (French: agglomération du Grand Nouméa), down from 182,341 at the 2019 census, and 85,976 in the city (commune) of Nouméa proper, down from 94,285 at the 2019 census. This is the first time since the start of statistical records that Greater Nouméa, which covers the communes of Nouméa, Le Mont-Dore, Dumbéa and Païta, has experienced a population decline.
At the 2025 census, 65.7% of the population of New Caledonia lived in Greater Nouméa, down from 67.2% at the 2019 census.
History
The first European to establish a settlement in the vicinity was British trader James Paddon in 1851. Eager to assert control of the island, the French established a settlement nearby three years later in 1854, moving from Balade in the north of the island. This settlement was initially called Port-de-France and was renamed Nouméa in 1866. The area served first as a penal colony, later as a centre for the exportation of the nickel and gold that was mined nearby.
From 1904 to 1940, Nouméa was linked to Dumbéa and Païta by the Nouméa-Païta railway, the only railway line that ever existed in New Caledonia.
During World War II, the United States Navy built Naval Base Noumea and Nouméa served as the headquarters of the United States military in the South Pacific. The five-sided U.S. military headquarters complex was adopted after the war as the base for a new regional intergovernmental development organisation: the South Pacific Commission, later known as the Secretariat of the Pacific Community, and later still as the Pacific Community.
The city maintains much of New Caledonia's unique mix of French and old Melanesian culture. Even today the United States wartime military influence lingers, both with the warmth that many New Caledonian people feel towards the United States after experiencing the relative friendliness of American soldiers and also with the names of several of the quarters in Nouméa. Districts such as "Receiving" and "Robinson", or even "Motor Pool", strike the anglophone ear strangely, until the historical context becomes clear.
In May 2024, protests and riots emerged in Nouméa and New Caledonia at large, due to concerns over an electoral bill that was seen as a threat towards potential independence. The unrest caused damage to the city, along with a major decline in tourism and an exodus of recently arrived residents (Metropolitan Frenchmen who returned to Metropolitan France as well as Kanaks and other ethnic groups who returned to their communes of origin in the rest of New Caledonia).

The mayor of Noumea is Sonia Lagarde; in 2020 her re-election was opposed by the former leader of the Confederation of Small and Medium Enterprises (CPME), Cherifa Linossier, whose unsuccessful campaign was based on local economic revitalisation.

The University of New Caledonia (UNC) dates to 1987 when the Université française du Pacifique (French University of the Pacific) was created, with two centres, one in French Polynesia and the other in New Caledonia. In 1997 the decision was made to split the two parts into separate universities and so in 1999 the Université de la Nouvelle-Calédonie and the Université de la Polynésie française were formed.
UNC welcomes around 3,000 local and international students and 100 professors and researchers each year.
The Bibliothèque Bernheim (Bernheim Library) is located in Nouméa.
