Belgium's largest cities in terms of population in 2024 were situated in Flanders. Approximately ******* people lived in Antwerpen, making it the biggest city in Belgium. This city was followed by Gent with ******* inhabitants in 2024. However, the third and fourth city with the most inhabitants were in the Belgian region of Wallonia. Indeed, Charleroi counted ******* inhabitants, and Bruxelles, ******* inhabitants.

In 2022, in terms of population, the biggest cities or municipalities in Belgium were Antwerp, Ghent, Charleroi, Liège, and Brussels. The Flemish cities of Antwerp and Ghent were the most populated in Belgium in 2022. From a regional perspective, out of the 6.8 million people living in Flanders, around 800,000 people lived in one of these two cities. However, the region of Wallonia also had large cities such as Charleroi and Liège. For instance, both cities registered around 200,000 inhabitants each. To put all these numbers into perspective, Belgium’s population amounted to 11.6 million in 2022.

Belgium’s capital city: Brussels

Surprisingly, the Belgian capital, Brussels, was not on top of the list. The reason for this is in the way the city’s population is measured. Brussels is made of 19 municipalities. In this ranking, for instance, only three of them are listed: Brussels City, Schaerbeek, and Anderlecht. These 19 municipalities form the heart of the agglomeration of Brussels which counts 36 municipalities in total and is also known as “le Grand Bruxelles”. In 2019, over a million people were living in this Brussels-Capital Region. The agglomeration of Brussels is the most populated in the country, it is bigger than the agglomeration of Antwerp. Yet in terms of municipalities, Antwerp was the most populated in Belgium in 2020.

Belgium’s five big agglomerations

Belgium faced a population growth of 0.58 percent in 2020. The country counts five big agglomerations: Antwerp, Brussels, Charleroi, Ghent, and Liège. Although the notion of agglomeration is very fluid and disputed, each of these five agglomerations represents a significant part of the population. For some, agglomerations are defined by the continuity of constructions. For others, they are defined by the sense of an urban entity shared by a living community. Nonetheless, the definition of an agglomeration in Belgium corresponds to the European rules. These rules fix the technical specifications regarding the population and housing census. An agglomeration is, therefore, a group of municipalities which includes a continuously built-up zone with no cut of more than 200 meters between two constructions.

Want to live somewhere quiet? Then the Brussels-Capital Region maybe would not be the place for you. In a country where the population density was highly depended on the region, the Brussels-Capital Region far exceeded the others in terms of residents per square kilometer. Whereas in Brussels over 7,500 people lived per a square kilometer, in the Walloon Region this was only 276. In total, roughly 1.22 million inhabitants lived in the Brussels-Capital Region in 2022.

 Flemish Region has the highest number of inhabitants  

Although the Brussels-Capital Region had the highest population density, it was by no means Belgium’s region with the largest number of inhabitants. On the contrary: both the Flemish and the Walloon Regions had more inhabitants than the Brussels Region. In total, just over ten percent of Belgium’s population lived in Brussels, the rest was divided among Flanders (58 percent) and Wallonia (32 percent).

 Comparison to the other Benelux countries   

Belgium’s population density amounted to 375 inhabitants per square kilometer in 2021. This was significantly lower than the population density in neighboring country the Netherlands, where on average 519 inhabitants lived on a square kilometer. It was however higher than Luxembourg’s population density, which amounted to about 245 inhabitants per square kilometer. This was the lowest population density of all three Benelux countries.

In 2023, the population of Belgium was approximately 11.7 million, and has grown by about 113,500 compared to 2022, when the population was 11.58 million.

How is the population distributed by region?
The population of Belgium is divided into three regions: the Flemish, Walloon, and Brussels-capital regions. The population of these regions is not distributed equally. In 2021, the Flemish region had 6.65 million inhabitants, compared to 3.65 million in the Walloon region and 1.22 million in the Brussels-capital region. The distribution between the regions has remained similar since 2009, with population increases in all regions staying relatively similar. With the population of Belgium expected to grow to 11.91 million by 2031, it will be interesting to see where these people will settle themselves.

How does Belgium’s population compare to the rest of Europe?
In 2021, Belgium had the 12th largest population in Europe, putting Belgium one place above Czechia and one below the Netherlands. Russia is the most populated European country with 145.9 million residents, meaning it has about 12.5 times the population of Belgium. The least populated country in Europe other than Vatican city is Gibraltar, with 34,000 inhabitants, meaning it has 0.3 percent of the population of Belgium.

The state of Belgium owes its name to Julius Caesar, who used the name "Belgium" to refer to the region in his narrative "The Gallic Wars". After the fall of the Western Roman Empire, the region emerged as a cosmopolitan trading center, and was a collection of smaller duchies and states (such as Flanders and Brabant), before modern history saw control of the region pass between France, the Netherlands and (to a lesser extent) Spain. Modern day Belgium emerged in 1830 following the Belgian Revolution when it gained independence from the Kingdom of the Netherlands. Throughout this time, the Belgian region was the setting of many conflicts between other European powers, which greatly affected the population development and demography of the area. From 1800 until the First world War, the population of Belgium grew steadily, and more than doubled in the nineteenth century. The World Wars Population growth stagnated in the 1910s, as a result of World War I and the Spanish Flu epidemic. Belgium was one of the focal points of military action in the war, and many military personnel from other nations also lost their lives here during the conflict. Much of the Second World War also took place in Belgium, and although it remained neutral at the outbreak of both wars, it was invaded twice by Germany due to its strategic importance. Belgium suffered an estimated 88,000 fatalities during the war; with many further military fatalities from other nations also perishing in the region. Continuous growth From 1950 onwards, Belgium's population grows at a relatively consistent rate, to more than ten million people the year 2000. Since the turn of the millennium, a positive net migration rate and higher life expectancy has meant that Belgium's population has grown even faster rate than in the twentieth century. Today, Belgium has a very high standard of living, and the capital city of Brussels is home to the headquarters of many international institutions, particularly the European Union.

This statistic provides information on the origin of the population of the City of Brussels.These statistics on origin are based on the following characteristics: the person's current nationality and first registered nationality, as well as the parents' first registered nationality. These characteristics are available in the National Register of Natural Persons (RNPP) managed by the SPF Intérieur. The starting point for determining origin is current nationality. If it is not Belgian, the person falls into the ‘non-Belgian’ category.If the current nationality is Belgian, the first nationality registered is looked at secondarily. If it is non-Belgian, the person falls into the ‘Belgian of foreign origin’ category. If the current nationality and the first registered nationality are Belgian, then the first registered nationality of the parents is examined. If one or both parents have a non-Belgian first registered nationality, then the person belongs to the ‘Belgian of foreign origin’ category.Finally, people who do not belong to any of the above categories are classified in the ‘Belgian of Belgian origin’ category.Nationality is finally subdivided into four main categories: Belgian; Neighbouring country, i.e. Germany, France, the Grand Duchy of Luxembourg, the Netherlands and the United Kingdom; EU27, excluding Belgium and neighbouring countries; Non-EU27.
