The comparative study of electoral system requires uniform methods easily applicable to every country's electoral data. In this paper we have presented two such possibilities: a new graphical method that portrays the proportionality profile of a country's electoral rule, and measures to calculate the systematic and random deviation from proportionality. The empirical data consist of election results from Denmark, Finland, Norway, and Sweden. Around 1950, Denmark, Norway, and Sweden changed from the d'Hondt method of allocation to the modified Sainte Lague rule. The consequences of this shift represent the primary focus of this article. What can the present Finnish constitutional reformers learn from the Scandinavian experience? According to the empirical results, three distinct patterns of proportionality profiles can be distinguished: 1) systems involving nationwide adjustment seats, 2) modified St. Lague (without adjustment seats) and 3) d'Hondt (without adjustment seats). The d'Hondt system gives a high advantage ratio to large parties, the modified Sainte Lague method favors middle‐size parties, and the adjustment seats system overrides the basic characteristics of both the d'Hondt and modified Sainte Lague methods. The proportionality indices show the modified Sainte Lague to be more proportional than the d'Hondt method. The proportionality of elections is nearly perfect with adjustment seats system irrespective of the method of allocation applied.
