Roma in the Czech Republic represent a large ethnic minority that faces intolerance and social exclusion. This study aims to describe factors that boost civic participation among Roma adolescents and emerging adults. Specifically, it asks whether different factors apply to Roma and members of the majority, and whether different factors boost offline and online participation. Survey data were analysed from Roma (n = 157) and majority (n = 573) participants between the ages of 15 and 28. Hierarchical regression models suggested that certain factors (a sense of collective influence and peer participatory norm) predict all forms of civic participation, regardless of ethnicity. For Roma youth, in contrast with the majority, offline participation was associated with a perceived lack of opportunities and unmet needs in their communities, which suggests that their offline civic participation might be a reaction to perceived communal problems. Finally, a lack of education was identified as a major explanation for lower rates of online participation among Roma.
