Canadian Election Study, 2004-2006

As a result of the Canadian Federal Election held on Monday June 28, 2004, the Liberal Party formed a minority government. Telephone surveys, conducted during the campaign and after the election with a random sample of Canadians, provide data that can be used to help explain the election outcome. Within 17 months, Canadians again went to the polls and the result of the January 23, 2006 vote was a second minority government, but under the leadership of the Conservative Party. Efforts were made to interview the respondents to the 2004 survey again for the 2006 survey and about one-half of the 2004 survey respondents also answered the 2006 survey. These re-interviews provide a panel or longitudinal sample component where a respondent’s answers to questions in the first survey can be compared to those of the second survey. Many of the questions asked in 2004 were repeated in the 2006 survey. The remaining respondents to the 2006 survey were a random sample of Canadians.

2004年6月28日周一举行的加拿大联邦选举中，自由党组建了少数派政府。研究团队在竞选期间及选举结束后，针对加拿大民众的随机样本开展电话调查，所得数据可用于辅助阐释本次选举的结果。仅时隔17个月，加拿大民众便再次参与投票，2006年1月23日的投票结果产出了第二个少数派政府，不过此次是由保守党领衔执政。2006年的调查尝试对2004年调查的受访对象进行回访，最终约有半数2004年的受访对象参与了2006年的调查。此类回访样本构成了面板（panel）或纵向（longitudinal）样本组件，可用于对比受访对象在两次调查中的作答内容。2004年调查中的多数问题在2006年的调查中被重复设置，2006年调查的其余受访对象则来自加拿大民众的随机抽样样本。
