The Transitional Justice Survey (TJS) was written and administrated by the author. It was based on 3,057 face-to-face interviews conducted in December 2004 by the Pentor Survey Research Company in Poland, Hoffman Research International in Hungary, and the Opinion Window Research International in the Czech Republic. In this appendix, I use Poland to describe the specific sampling technique used in the Transitional Justice Survey. I use the Hungarian version of the question-naire.

The Sampling Technique

The Polish part of the survey was conducted using the omnibus technique with direct, face-to-face interviews of 1,006 persons representative of a random sample of the population aged fifteen and older. As a result, only two-thirds of the samples included citizens who at the time of the survey were at least twenty years old. However, when the samples were split into those respondents who at the time of the survey were younger than thirty-five and those who were older than thirty-five, the between-group differences in the dependent variable and independent variables of interest were not sensitive to age (even in variables such as involvement in the secret police and opposition networks) and were insignificant at the 90 percent confidence intervals (CI). Furthermore, in Poland, the younger cohort showed a higher average number of persons known in both the secret police and opposition networks. In all three countries, average transitional justice (TJ) demand was higher among the younger cohort, although at the 90 percent level, insignificantly so.
