Monaco’s resident population continued to rise in 2025, reaching 38,857 people as of December 31 2025, according to the latest census report published by IMSEE…

The figure marks an increase of 434 residents over one year, or 1.1 percent, bringing the Principality closer to 39,000 inhabitants.

The report confirms Monaco’s remarkable demographic diversity, with 144 nationalities represented across its two-square-kilometre territory. Monegasques remain the largest nationality group for the third consecutive year, accounting for 24 percent of the population, followed by French residents at 21.3 percent and Italians at 19.5 percent. British residents recorded the strongest annual increase, with 163 additional people in 2025, while the French population fell by 100 over the same period.

Monte-Carlo remains the most populated district, with 8,318 residents, followed by La Rousse with 7,992. Together, the two districts account for more than four in ten residents. La Condamine has 5,446 residents, Jardin Exotique counts 4,997, Les Moneghetti 4,498 and Fontvieille 4,297. Monaco-Ville remains the least populated district, with 1,022 residents.

The census also points to an ageing but increasingly balanced population. The average age stands at 47.2 years, while nearly 5,800 residents are aged 75 or over. Women account for 50.8 percent of the population, compared with 49.2 percent men, continuing a long-term move towards gender parity.

More than 2,700 adult foreign residents have settled in Monaco since 2023, led by arrivals from France, Italy, the United Kingdom, Russia and Switzerland. The report also notes that more than one-third of working-age residents hold salaried employment in Monaco.

Housing stock also increased, with 22,577 residential units recorded in 2025, up 1.8 percent in one year. More than 80 percent are private dwellings, while state-owned housing accounts for 19.4 percent of the total, with the highest concentrations in Fontvieille, Jardin Exotique and La Condamine.

The 2025 census is the third compiled under Monaco’s new register-based system, introduced in 2023 to provide annual demographic updates using administrative data rather than traditional field surveys.
