The data were collected from a representative sample of adult citizens (over 18 years old) of the Republic of Croatia via random sampling using the birthday key method. The sample comprised 1000 people and was collected using the F2F-CAPI method from 18.9 to 2.10 2016. Data were weighted by the 2011 Croatian census (region, settlement size, age, and gender). The goal was to collect data on citizens' voting behavior and political attitudes after Croatia's 2016 snap parliamentary elections (post-election survey).
