There is only few information available about the use of preferential votes at local elections, since the Belgian Home Department does not publish that particular statistical material. This article registers the size of preferential voting and discusses its consequences for the local political system, based on statistical data collected in the 43 municipalities of the Limburg province where local elections were held in 1988. Nearly 9 of the 10 voters used the preferential vote to express their choice. This is a much higher level than the one noticed at the general elections. The use of preferential votes is varying according to the size of the municipalities (more preferential votes in the smaller ones) and differs from one party to another (f.e. 92.7 % for the christian-democratic parties to 47.1 % for the radical left). The local election system and the size of preferential votes at local elections explain why nearly 7 of the 10 local councillors broke through the order of the candidate-list. For the comparison, this occured only twice at the 1991 general elections.
