Participatory budgeting is a process of democratic decision-making in which ordinary people take part in preparing and adopting a municipal or public budget. In the Baltic Sea region, only a few municipalities have applied participatory budgeting to date. A typical type of citizen in such a process is male, politically active, well-educated, and 35-65 years old. The objective of EmPaci is to get more municipalities involved and mobilise different types of citizens by building municipal capacities, transnational clusters and municipality-citizen cooperation.
