Between 2011 and 2020, three waves of a panel survey have been carried out in Egypt, Tunisia, and Turkey. In Egypt, of a nationally representative sample of 3,496 adults interviewed in 2011, 2,430 were re-interviewed in 2016 (response rate of 70%). To compensate for sample attrition, 1,428 additional interviews were conducted, bringing the total of interviews to 3,858. Of this number, 3441 were located and re-interviewed in 2020. In Turkey, of a nationally representative sample of 3,019 adults interviewed in 2013, 1,682 were re-interviewed in 2016 (a response rate of 56%), plus a sample of 1,077 additional interviews to compensate for sample attrition, bringing the total to 2,759. Of this number, 1442 respondents were re-interviewed plus a sample of 1063 additional interviews were conducted to compensate for sample attrition, bringing the total of interviews to 2505 in 2020. In Tunisia of a nationally representative sample of 3,070 respondents interviewed in 2013, 2,395 were re-interviewed in 2015 (a response rate of 78%). Of this number, 1485 respondents were re-interviewed plus a sample of 913 additional interviews to compensate for sample attrition, bringing the total to 2398 interviews in 2020. Altogether, the three waves produced a total of 26,941 completed interviews. The analysis of these extensive datasets across the three countries in three waves show significant changes in the sociopolitical and cultural values of the respondents toward expressive individualism, gender equality, secular politics, liberal values, and religious tolerance in Egypt and Turkey. While the Tunisian respondents were also experiencing the same trend between wave one and wave two, in wave three there was a significant drop in their support for secular politics, liberal values, and religious tolerance. Attitudes toward gender equality, however, remained unchanged among the Tunisian respondents between the last two waves. This paper further discusses the implications of this trend for a better understanding of cultural change across the three countries and beyond in the post Arab Spring.
