This article represents an analysis of efficiency of Ukrainian democracy within the framework of three popural indices of democracy – The Economist Democracy Index, Freedom In the World index and Polity IV. Comparative analysis shows the core factors which bring three different democratic concepts, used in the indices, to the integral unity. Finding correlation between factors of Ukrainian democracy, measured in the indices through a certain time period (2006-2018), helps getting integral look at the problem of non existent universal theoretic base for understanding democracy. The basic idea of the analysis, represented in this article, shows that different factors, used by indices in measuring democracy, do not evenly correlate in practice, though they represent holistic approach to the essence of democracy. Choosing specific theoretical approach of understanding democracy makes it hard for indices to fully measure real democracy. This analysis aims at searching correlation in different basic factors of democratic models, used by indices with different approaches. As the result of the analysis the article ranks a number of basic factors, used in three popular indices of democracy, according to the strength of correlation of these factors with other factors of the index they represent and with the final score of the index. Integral choice of the basic factors, which correlate with the change of Ukraine’s democratic trends according to the three indices, covers several dimensions of democratic model. Ukrainian democratic trends in the specific time period (2006-2018), as the analysis shows, from integral point of view correlates the most with the changes in electoral process and pluralism, civil liberties and legal restrictions of the executive power. Political culture, political participation and individual rights show weak correlation with Ukrainian democratic trends within the period of time, chosen for the analysis.
