This dataset shows, for each Brussels municipality, the projected population by age and sex, over the period from 2026 to 2035. The population projections are carried out according to the methodologies described in the Cahier of the BISA No. 13.

For each Brussels municipality, this dataset includes the number of members of municipal councils, inhabitants, voters, votes, valid votes and seats according to lists. The data cover the results of the Brussels municipal elections from 2006 until the most recent elections. The members of the municipal council are elected every six years by all the voters in the municipality, for a period of six years.

This dataset corresponds to the macrozone dataset, i.e. the highest-level statistical partition of the Brussels-Capital Region (the Region is divided into 17 macrozones).

This dataset corresponds to the updated list of Belgian municipalities belonging to an urban region, based on the analysis published in IBSA Report No. 17. The data covered by this dataset range from 2021 to 2025, and the municipal boundaries are those of 2025.
