Nearly one in eight self-employed workers in Belgium do not hold Belgian nationality. This proportion rises to more than four in ten in the Brussels-Capital Region. An analysis of recent data from the National Institute for Social Security of the Self-Employed (INASTI) by the social insurance fund Acerta highlights these figures. The study also reveals differences in age, sector activity, and income between Belgian and non-Belgian self-employed individuals.

As of 1 January 2025, more than one-third of Belgium’s population has a foreign background, according to the latest data from Statbel, the Belgian statistical office. While 64% of residents are Belgian with a Belgian background, the remainder includes Belgians with a foreign background and non-Belgians. Regional disparities and changes over the last two decades highlight evolving demographic patterns.

According to the figures released by Statbel, the Belgian statistical office, the share of Belgians with a Belgian background has decreased from 79,9% in 2004 to 64,8% in 2024. The share of Belgians with a foreign background increased by 5,1 percentage points between 2004 and 2014. The proportion of non-Belgians increased from 8.3% in 2004 to 13.7% in 2024.
