Two square kilometers, barely more than the Bois de Vincennes divided by fifteen. It is on this surface that a population larger than that of many French sub-prefectures lives, in a sovereign state with its own nationality, its own army, and a seat at the United Nations.
The Principality of Monaco condenses in a few hectares a record density, seven centuries of dynastic history, and a unique economic model in Europe. Detailed fact sheet.
Identity sheet: two square kilometers between sea and mountain
Monaco occupies 2.08 km² on the French Riviera, about fifteen kilometers from the Italian border. The territory stretches over approximately four kilometers of Mediterranean coastline, wedged between the sea and the mountainous foothills of the Alpes-Maritimes.
The Principality is entirely landlocked within the French department, bordering three municipalities: Cap-d’Ail, Beausoleil, and Roquebrune-Cap-Martin. It shares no land border with Italy, contrary to a persistent misconception.
This configuration explains the verticality of the territory. Between sea level and the upper neighborhoods, the elevation difference is overcome by a network of public elevators and escalators, a rare feature at the scale of a state.
Regarding international identifiers, the Principality is designated by the code MC in the ISO standard, which is found on its national internet domain and in most geographic databases. Our table of 2-letter country codes lists the equivalent for all countries worldwide.
A density unmatched in the world
The census conducted by the Monaco Institute of Statistics and Economic Studies counts 38,367 inhabitants, for an average density exceeding 18,400 inhabitants per square kilometer.
This figure makes Monaco the most densely populated state on the planet. The nuance is worth noting: some metropolises reach comparable densities within their municipal territories, but no country approaches this at the national scale, due to not having such a small territory.
The population presents another peculiarity. The Monegasques are a minority, around 23 to 24% of residents, the rest being divided among nearly 150 nationalities. Monegasque nationality is mainly transmitted by descent and is rarely granted by naturalization.
The neighborhoods of the Principality
Four areas historically structure the territory.
Monaco-Ville, the Rock, occupies a limestone peninsula overlooking the sea. The princely palace, the cathedral, and the oceanographic museum are concentrated there in a maze of medieval alleyways. It is the least populated neighborhood, with just over a thousand inhabitants.
La Condamine borders Port Hercule, the only deep-water port of the Principality and the heart of its maritime activity.
Monte-Carlo developed from 1866 around the casino, originally the financial turnaround of the state after the loss of its agricultural territories.
Fontvieille, finally, constitutes the modern extension to the southwest, entirely built on the sea.
The administrative division of the census distinguishes other sectors, including Larvotto and its beaches, the Exotic Garden, and the Moneghetti, which concentrate a significant portion of the housing stock.
To visualize the distribution of these neighborhoods on the ground and identify the main points of interest, the Monaco map usefully complements this description.
A territory gained from the sea
Unable to expand, Monaco chose to create its own land. The first landfills date back to the 1860s, and since then the Principality has reclaimed about forty hectares from the Mediterranean, nearly one-fifth of its current area.
The most emblematic project remains Fontvieille, about thirty hectares reclaimed from the water between the 1970s and 1990s under the reign of Prince Rainier III. The neighborhood now hosts housing, a marina, a stadium, and a business zone.
The most recent development was delivered in December 2024: the Mareterra eco-neighborhood, on the Portier Cove, adds about six hectares and one hundred thirty housing units to the national territory. Administratively attached to Larvotto, it illustrates the continuation of a strategy over one hundred sixty years old.
Seven centuries of Grimaldi
The dynasty settled on the Rock in 1297, the founding date of Monaco’s history. The sovereignty of the Principality was recognized by the Treaty of Péronne in 1641.
The decisive episode occurred in 1861. By treaty with France, Monaco renounced Menton and Roquebrune, which represented the largest part of its area and its only agricultural lands. The Principality then lost most of its territory and was forced to invent a new economy.
The answer lies in one word: Monte-Carlo. The opening of the casino and the creation of the Société des bains de mer transformed a ruined state into a European fashionable destination.
Monaco joined the United Nations in 1993. Prince Albert II has reigned since 2005.
An economy without income tax
The abolition of personal income tax dates back to 1869, a measure made possible by gambling revenues. It remains today one of the most discussed features of the Monegasque model.
A major exception exists: under the Franco-Monegasque tax convention of 1963, French nationals residing in Monaco since 1957 remain taxable in France.
The economy relies on financial activities, real estate, high-end tourism, commerce, and marine sciences. The labor market far exceeds the territory’s scope: the Principality has more than 60,000 private sector employees, significantly more than its resident population, the gap being filled daily by cross-border workers from France and Italy.
Housing and real estate market: land pressure at its maximum
On a finite territory where every square meter has been negotiated from the sea or the mountain, housing constitutes the most sensitive issue of the Principality.
The housing stock is divided into three distinct sectors. The state-owned sector gathers housing belonging to the State and reserved for Monegasques. The so-called protected sector is primarily intended for the country’s children and certain long-term residents, with regulated rents. The free sector, finally, follows only market rules.
It is the latter that gives Monaco its reputation. Prices per square meter are among the highest in the world, several tens of thousands of euros on average, with peaks on waterfront properties or in new residences. The structural scarcity of supply, constrained by geography, mechanically maintains these levels.
Buyers who wish to purchase a property in Monaco generally go through locally established agencies, the only ones with a complete view of a market where a significant portion of transactions is never publicly advertised.
Successive extensions into the sea directly respond to this tension. Each new district adds a few hundred homes to a stock that cannot grow otherwise.
Monaco remains a textbook case in geography: a state that, lacking space, has spent one hundred and sixty years creating it.
FAQ: Monaco in Numbers
What is the exact area of Monaco?
The Principality covers 2.08 km², making it the second smallest state in the world after the Vatican. Nearly one-fifth of this area has been reclaimed from the sea since the 1860s, through successive land reclamation operations.
How many inhabitants does Monaco have?
The latest census reports 38,367 inhabitants, with a density exceeding 18,400 people per square kilometer, the highest in the world at the scale of a state. Monegasques represent about a quarter of the residents, alongside nearly 150 nationalities.
Why is there no income tax in Monaco?
The abolition of this tax dates back to 1869 and was made possible by revenues from the Monte-Carlo casino. French nationals residing in the Principality since 1957 remain taxable in France, under the Franco-Monegasque tax convention of 1963.
What is the Mareterra district?
This is the most recent extension into the sea of Monaco, delivered in December 2024 on the Portier Cove. This new district adds about six hectares and one hundred and thirty homes to the territory, and is administratively attached to Larvotto.
