This dataset contains information about the descriptive representation of immigrant-origin citizens at the 2018 local elections in Flanders. It covers 31,176 candidates over 1,312 lists. For each candidate list, this dataset contains information about the percentage of immigrant-origin candidates, their average relative list position and the proportion of elected immigrant-origin candidates. Extra variables are added at the party level (e.g., whether it was part of the local government prior to the 2018 local elections or whether the head of list had an immigrant background) and municipality level (e.g., population density or percentage of the immigrant-origin population) to allow a profound examination of which factors steer the descriptive representation of immigrant-origin citizens.
