Monaco’s population reached 38,857 residents in 2025, according to the latest census data published by IMSEE in March 2026 — an increase of 1.1% on the previous year, equivalent to 434 additional residents.
The Principality now draws residents from 144 different nationalities, with Monegasques remaining the largest single group at 24% of the population — 9,333 nationals in total. French residents follow at 21.3%, with Italians close behind at 19.5%.
British residents rank fourth, accounting for 7.9% of Monaco’s population — a significant share that underscores the Principality’s growing appeal as a destination for UK nationals seeking fiscal stability and security in an increasingly uncertain world. That figure places the British community well ahead of the Swiss (3.2%), Russians (3.1%), Belgians (2.7%) and Germans (2.5%).
Who is moving to Monaco
Among adults who established residency in Monaco between 2023 and 2025 and remained as of 31st December 2025, France accounts for the largest share of new arrivals at 30.6%, followed by the United Kingdom at 18.9% and Italy at 9.4%. The strong showing from British newcomers in particular reflects a pattern Monaco Life has tracked over recent years: post-Brexit tax and residency planning has made Monaco an increasingly attractive base for high-net-worth individuals from the UK.
The average age of new adult residents is 44.7 years — 46.1 for men and 43.3 for women — suggesting a population arriving in its prime earning and wealth-accumulation years.
A population getting slightly older
Monaco’s overall average age stands at 47.2 years, with men averaging 46.5 and women 47.7. The largest age cohort is the 50 to 64 bracket, accounting for 23.4% of residents, followed by the 65 to 79 group at 17.9%. Just over half of residents aged 18 and above — 50.6% — are married.
Women make up a slim majority of the population at 50.8%, or 19,730 residents, compared to 19,127 men.
