Citizenship

Foreign citizenship ratio
Content

This indicator is calculated by dividing the number of foreigners by the total population, except for stateless persons and persons with undetermined citizenship.

More than 12% of the population living in Belgium has a foreign citizenship.

In the Brussels-Capital Region, more than 1 inhabitant out of 3 is not Belgian. Etterbeek (49%), Ixelles (49%) and Saint-Gilles (48%) have the highest percentages of non-Belgians.

In the Flemish Region, 9% of the inhabitants do not have the Belgian citizenship. In the Walloon Region, it is 10%.

At municipal level, percentages are well above the national average, mostly in big cities and in border municipalities.

Citizenship of an EU country
Content

The share of foreigners with the citizenship of an EU country (27 countries) is calculated as the ratio between this population and the total population, except for stateless persons and persons with undetermined citizenship.

Around 8% of the population living in Belgium has the citizenship of another EU country. These regional variations are significant: this figure is 6% in Flanders and 7% in Wallonia, versus 23% in the Brussels-Capital Region. The municipalities of Ixelles, Etterbeek and Saint-Gilles particularly stand out with more than 35% of their inhabitants having the citizenship of another EU country.

Outside the Brussels-Capital Region, the border municipalities also show high percentages of foreign citizens from the European Union.

Citizenship of a non-EU country
Content

This indicator is calculated by dividing the number of non-Belgians who are not citizens of one of the countries of the European Union (27 countries) by the total population, except for stateless persons and persons with undetermined citizenship.

Slightly more than 4% of people living in Belgium have the citizenship of a non-EU country. Wallonia and Flanders show lower figures, with 3% and 3.5% respectively. However, nearly 12% of the inhabitants of the Brussels-Capital Region have the citizenship of a non-EU country. The 11 municipalities with the highest percentage are located in this region; Saint-Josse-ten-Noode is first with 17.9%.

The Census 2021 in a nutshell

The Census 2021 is a snapshot of the population living in Belgium on 1 January 2021. It provides a wide range of figures on housing and demographic, socio-economic and educational characteristics of the citizens. The objective of the Census is twofold: to comply with the European regulation[1] and to produce statistics to address national specific needs (public services, international organizations, researchers, enterprises and private individuals).

Previously based on an exhaustive survey of all citizens, since 2011 the Census has been based exclusively on the use of administrative databases.

Definitions

The various statistical units

Population

The population taken into account for the Census 2021 is the residential population, as registered in the National Register of Natural Persons (RNPP) on 1 January 2021. The Belgian population includes Belgians and non-Belgians who have been allowed or authorised to settle or to stay in Belgium but does not include non-Belgians living on the territory for less than three months, asylum seekers and non-Belgians in an illegal situation[2].

Private households

This group includes people living alone in a dwelling and groups of several people living in the same dwelling and providing themselves with essentials for living.

Family nuclei

A family nucleus is defined as two or more persons who belong to the same household and who are related as husband and wife, as partners in a registered partnership, as partners in a consensual union, or as parent and child.

Living quarters

Living quarters refer to all quarters used as the usual residence of one or several persons.

Conventional dwellings

Conventional dwellings are separate units (surrounded by walls and covered by a roof) that are independent (with a direct access from the street or a staircase, passage) and designed to be used as a permanent dwelling.

Occupied conventional dwellings

Occupied conventional dwellings are conventional dwellings used as the usual residence of one or several private households.
