Article description: (description)
This attribute controls the content of the description and og:description elements. | The effective number of parties (or effective number of political parties, ENP, ENPP) is a concept introduced by Laakso and Taagepera (1979)[1] which provides a measure of the number of political parties of a party system. The concept is to weight the parties by their support so as to answer how many equally-sized parties are equivalent to the number of parties observed. For instance, a party with hardly any support would only count as a fraction of an "equally sized party": a dominant party system would not be considered two-party if the second party obtains very few votes. |
