European Parliament Election Study 2014

The European Parliament Election Study 2014 was conducted in collaboration between the Department of Political Science in Gothenburg and Statistics Sweden (SCB). This collaboration has covered all of the parliamentary elections, referendums and elections to the European Parliament since 1956.

In 2014 the Swedish National Election Studies (SNES) team changed the primary mode of the study from face to face to a 24
page mail-back paper survey. One of the main reasons for the mode change was the ever increasing
costs of preforming face to face interviews. Another reason was to combat the trend of declining
response rate and to ensure large enough (n) in the study. As a result the sample size was doubled to
5400 individuals.

2014年欧洲议会选举研究由哥德堡大学政治学系与瑞典统计局（SCB）联合开展。自1956年以来，双方的合作已覆盖所有议会选举、全民公投及欧洲议会选举。

2014年，瑞典全国选举研究（SNES）团队将研究的主要方式从面对面访谈改为24页的邮寄回收纸质问卷。模式变更的主要原因之一是面对面访谈成本持续攀升，另一个原因则是为应对应答率下降的趋势，确保研究具备足够大的样本量（n）。因此，样本量翻倍至5400人。
