Parliament (Riksdag) elections
The social-democratic party has dominated Swedish government for the most part of the last 70 years, but for shorter periods a bloc of non-socialist parties have been in majority and formed the cabinet. In the balance between the two main political blocs small changes in voters� choice can change the majority in electoral districts (communes) and parliament. The core areas of socialist and non-socialist majorities are relatively stable over time and can be compared with other social indicators.
