The aim of this paper is to analyze the social and class inequalities in turnout in the Czech Republic between 1990 and 2010. Thus, the study focuses on a description of the evolution of the relationship between turnout and key characteristics of socio-economic status: education, income and social class. This research utilizes a pooled cross-sectional post-election survey dataset from the Czech Republic fielded over two decades; and employs standard statistical methods, i.e. contingency tables and convergence models, to analyze change in turnout among population subgroups. There are signs of a gradual crystallization of both social and class inequalities in electoral participation. Convergence models reveal a linear increase in educational and class inequalities in turnout. In the case of income, however, this study finds evidence of a crystallization of income based inequalities in participation rather than a growth in inequalities per se., Lukáš Linek., and Obsahuje seznam literatury
