The 2012 Hellenic (Greek) National Election Voter Study was conducted as a mixed-mode survey in the period between 19 October 2012 and 5 January 2013. The sample was selected randomly by area proportional to total phone population. Half of the sample was designed to be collected online. The selected respondents were called on the phone and they were asked to provide their email address if they wanted to participate in a web survey conducted by the Laboratory of Applied Political Research, Aristotle University of Thessaloniki. These email addresses have been used into the epolls.gr web survey system. The other half of the sample was designed to be collected by face-to-face interviews. For the face-to-face sample, additional weight was given to people from rural areas, aged >= 55 years and with lower educational levels (taking into consideration the limited access and use of the Internet of these groups). The final dataset consists of 529 respondents to the web survey and 500 respondents to the face-to-face interviews. The telephone recruitment of the web survey respondents and the F2F interviews have been conducted by To The Point. We are grateful to Pedro Magalhães (Instituto de Ciências Sociais da Universidade de Lisboa/ ICS) for sharing the battery of questions on the economic crisis of the Portuguese National Election Study 2011.
