Referendums and elections

Anyone conducting research on elections and referendums depends on carefully prepared, current, and publicly available data sets. The ZDA maintains an internationally unique database on initiatives and referendums in the whole world.

Mandated by the Federal Statistical Office (FSO), the ZDA also maintains a database on the Swiss elections and referendums. The goal is an early detection of national political trends. Subject to research are also how national elections and voting on issues, as well as cantonal and municipal elections, influence each other.
