VALU 2022 - SVT exit poll survey parliamentary election 2022

This exit poll survey (VALU) was carried out at the parliamentary election 2022 by Sveriges Television (SVT) in collaboration with researchers at the Division of Safety Research, Royal Institute of Technology (KTH), Stockholm and the Department of Political Science, University of Gothenburg. The main purpose of VALU 2022 was, as for previous exit polls, to provide analytical support for the election night broadcast on Swedish television during the election night, as well as for other post-election analyses.

In VALU, voters leaving polling stations are asked by public service broadcaster Sveriges Television to fill in a questionnaire and put it anonymously in a sealed box. After collecting and processing the responses, Sveriges Television can present an election forecast and an analysis of the reasons underlying the outcome of the election in its election night broadcast. The surveys are referred to as VALU, an abbreviation for vallokalsundersökning, Swedish for exit poll survey. 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.

本次投票后民调（VALU）由瑞典电视台（Sveriges Television, SVT）于2022年议会选举期间，与瑞典皇家理工学院（Royal Institute of Technology, KTH）安全研究部以及哥德堡大学（University of Gothenburg）政治科学系的研究人员合作开展。VALU 2022的核心目标与既往投票后民调一致，旨在为瑞典电视台的选举夜直播及其他选举后分析工作提供分析支撑。
在VALU调研流程中，瑞典公共服务广播机构瑞典电视台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箱。待回收并处理问卷数据后，瑞典电视台便可在选举夜直播中发布选举预测报告，并针对选举结果的成因开展分析。该调研被称为VALU，是瑞典语词汇vallokalsundersökning的缩写，该词意为投票后民调。瑞典的首次投票后民调于1991年议会选举期间开展，自此之后，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。
在VALU调研中，瑞典的选区以主要大学城为核心划分为若干地理区域，每个区域均聘任一名大学教师担任区域调研负责人。该负责人将对分别在投票站与提前投票站开展实地调研的外勤人员进行督导，所有区域调研负责人均需掌握统计方法论相关知识。
