RepResent Longitudinal survey 2019 - 2021

The target population of the study are the inhabitants of Flanders, Wallonia, and the Brussels Region that were eligible to vote for the elections of May 26, 2019. The gross sample consisted of respondents that were recruited from diverse online panels (Kantar’s own panel as well as panels from other online companies such as Dynata). The target was a net sample that would match the distribution on gender, age and education for the voting aged population in their respective regions.

Due to non-response, the final samples differ from the target population distributions somewhat, but weights are provided in the dataset to set the sample distributions to match the population distributions. The initial target was to have a net sample of 2500 respondents at the end of the second wave (1000 respondents in Flanders and Wallonia and 500 respondents in the Brussels Region). During the fieldwork, however, it was decided to oversample and continue the data collection even when the target was reached to be able to conduct a third and potentially fourth wave during the legislative term.

For the third and fourth waves no target was set: the aim was simply to maximize responses.
