Population density in Belgium 2022, by region
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.
