Niche parties in the Benoit and Laver expert survey Note: 1) This list is not to be treated as exhaustive as the expert survey restricted itself to the most important parties in each country. Many smaller parties are therefore not included in the dataset. 2)Only countries with more than three parties are included in the analysis as it is not reasonable to calculate mean salience scores with just one or two competitors. While smaller party systems may also have niche parties, it is difficult to assess relative levels of salience if the number of other competitors is so small. This excludes Malta and the United States from the sample for this survey. 3) Party family information is taken from the CMP dataset. 4) For more on the survey and precise question wording, see: Benoit, K. and M. Laver (2006) Party Policy in Modern Democracies, Routledge, London.
