VALU 2018 - SVT exit poll survey parliamentary election 2018

This exit poll survey (VALU, an abbreviation for vallokalsundersökning) was carried out in connection with the parliamentary election on September 9, 2018. In VALU voters leaving polling stations are asked by public service broadcaster Sveriges Television (SVT) to fill in a questionnaire and put it anonymously in a sealed box. After collecting and processing the responses, Sveriges Television is able to present an election forecast and an analysis of the reasons underlying the outcome of the election in its Election Night broadcast. The first exit poll survey in Sweden was carried out at the parliamentary election in 1991. Since then similar studies have been carried out in connection with all Parliamentary elections, referendums and elections to the European Parliament. In VALU, Sweden (constituencies) is divided into geographical regions grouped around major university cities. In each of the regions, a university teacher is engaged as regional survey leader. The survey leaders act as supervisors for the field agents who carry out the survey in the polling stations and early voting stations respectively. All survey leaders have knowledge of statistical methodology. Purpose: Provide analytical support for the election night broadcast on Swedish television during the election night, and for other post-election analysis.本次出口民调（VALU，为瑞典语vallokalsundersökning的缩写）系针对2018年9月9日议会选举开展的配套调研。 在VALU项目中，瑞典公共电视台（Sveriges Television，简称SVT）会邀请离开投票站的选民填写问卷，并将问卷匿名投入密封收纳箱。待收集并处理所有问卷数据后，瑞典公共电视台可在其选举夜直播中发布选举预测报告，并对选举结果的成因展开分析。瑞典的首次出口民调于1991年议会选举期间开展，自此之后，瑞典所有议会选举、全民公投以及欧洲议会选举均配套开展了同类调研。 VALU项目将瑞典全国选区划分为以主要大学城为核心的地理区域，每个区域均聘任高校教师担任区域调研负责人，其职责为督导分别在投票站与提前投票点开展调研的外勤人员。所有区域调研负责人均具备统计学方法论相关专业知识。 调研目的：为瑞典电视台选举夜直播及其他后续选举分析工作提供分析支撑。
