Korsholm2020 is a research project funded by Högskolestiftelsen i Österbotten. The aim of this project is to analyze how the political environment is affected by municipality level referendums. The project is directly related to the fact that there has recently been two referendums in Ostrobothnia regarding proposed municipality mergers. For this research purpose, a survey will be conducted in one of these municipalities, Mustasaari, during the autumn of 2020, with the specific aim of collecting survey data about the effects on public opinion derived from a referendum process. The results will be presented in a public report in the beginning of 2021.
