This paper presents evidence from interviews in 2015-2016 with a nationally representative sample of Tunisia's 15-29 year olds. We focus on the sample's political participation and orientations during the revolution of 2011 and subsequently. We find that just 6.6 percent of those aged 15-24 at the time played any direct part in the 'events of 2011'. Political engagement then and subsequently is shown to have been influenced most strongly by a university education and growing up in a politically engaged family. In 2015-2016, young people were overwhelmingly pro-democracy, supported equal opportunities and status for the sexes, and endorsed values of self-expression, but attached equal importance to economic security and betterment, felt that their country's traditions should be maintained and respected, and were personally religious, though three-quarters wanted religion to be kept out of politics and government. Although Tunisia is the sole Arab Spring country to emerge with a still functioning (in 2017) multi-party democracy, we find that in 2015-2016, the majority of young people did not trust their elected politicians. Our survey findings suggest explanations for the paradox between young Tunisians' overwhelming support for democracy alongside intense disappointment with the outcomes.
