They planned to interview a total of 800 young people (aged 20 to 30 years), from four Western Balkan countries: Serbia (Belgrade, Novi Pazar), Macedonia (Skopje, Tetovo), Bosnia and Herzegovina (Banja Luka, Sarajevo) and Kosovo (Prishtina, Mitrovica). They planned to have 100 participants per town.
In each country, two towns were chosen: one in which ethnic majority on state level has majority status, and the other in which it has minority status. In each town, we targeted to have at least one third of ethnic minorities. The sample frame within each city was balanced gender-wise and based on majority-minority status. We also aimed to have a diversity in education level of the respondents, so we further divided the quota based on the highest level of the educational attainment achieved.
They collected the sample via passive snowballing method. In each city the researchers assigned university students to find the respondents to participate in the survey, broken down by quotas.
They collected the data in lab conditions. Respondents were required to come to the prearranged facilities (rooms), which had computers with internet access. The data were collected via Electronic questionnaire, based on Qualtrics survey platform. Maximum 3 persons were tested simultaneously.
