Through a series of articles on Belgian demographics, you will discover the changes in the population structure over the last ten years and how these changes affect you. The first essential question: is the Belgian population growing?

Are there more and more people in Belgium?

Yes, the Belgian population is increasing every year. In 2021, there were almost 600.000 more inhabitants than in 2011. The total population is now 11,5 million. Over a single decade, the population of Belgium has grown by 5%. The regional distribution of the Belgian population is as follows: 57% in Flanders, 32% in Wallonia and 11% in Brussels.

Is the population growing everywhere in Belgium?

If we look closely at the demographic data for the last ten years, we can see that the population increase is happening throughout the entire country, but not at the same pace. Brussels is where the number of inhabitants is increasing the fastest. Between 2011 and 2021, its population increased by 9%, while Flanders and Wallonia saw increases of 5% and 3% respectively.

At a more granular level, we can see important differences between the growth rates of each of the provinces. After Brussels, the most marked increases in the number of inhabitants occurred in Flemish Brabant, Luxembourg and Antwerp. The population of Flemish Brabant grew by 7%, while the other two provinces saw increases of 6%. Conversely, the province of Hainaut now has only 2% more inhabitants than in 2011.

Population growth per province

More inhabitants, more needs to be met

Growth in the number of inhabitants, and therefore in the number of consumers, causes changes in the needs of the population. These needs relate to schools, healthcare, trades and services of different kinds. For merchant and non-merchant actors like yourselves, it is essential to understand the local variations, as well as the impact on the services you offer.
