the distribution of seats among the electoral districts was as follows for the chamber of representatives. seats were reapportioned among the districts due to population growth, which was stronger in flanders than in wallonia, and due to several municipalities having been changed to another province following the 1962 language laws. for example, the comines-warneton municipalities were transferred from ypres (west flanders) to the newly created arrondissement of mouscron (hainaut), causing ypres to lose one seat and tournai-ath-mouscron to gain one seat.
