2020 Cooperative Election Study

2020年合作选举研究是美国50多个不同大学研究团队的合作。该小组共同设计并开展了一项针对至少5万名美国成年人的大型抽样调查。该调查衡量了全国和州选举中的人口统计、态度和投票行为。非常大的样本量使研究人员有足够的数据来研究州选民以及整个国家。这项调查用于研究谁投票，为什么投票，以及如何解释选民做出的选择。自成立以来，CCES已涉及100多个不同的研究团队和数百名教师和学生研究人员，并对30多万美国成年人进行了采访。这个项目的数据被研究人员、记者和公众广泛使用，以了解美国的选举和民意。2020年合作选举研究是由一个研究团队联盟开发的。每个希望参与该项目的研究团队都从同一家公司购买一份1000人的抽样调查。每个小组决定其调查中一半的问题。另一半内容（公共内容）由设计委员会从参与的团队中选出。公共内容由每个团队想要测量的问题或具有广泛兴趣并需要非常大样本的问题组成。因此，该项目进行了尽可能多的调查，因为有团队，也产生了一个单一的大样本调查，包括公共内容。该调查将通过互联网进行，样本将具有全国代表性。每个团队将从自己的1000人调查中获得数据，并从共同内容调查中获得由50,000多个观察结果组成的数据集。调查数据通过选民验证和州级选举结果与每个州子样本的调查结果的比较来验证。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The 2020 Cooperative Election Study is a collaboration of over 50 different university research teams throughout the United States. Collectively this group designs and fields a large sample survey of at least 50,000 American adults. The survey measures demographics, attitudes, and voting behavior in national and state elections. The very large sample size allows researchers to have sufficient data to study state electorates as well as the entire nation. The survey is used to study who votes and why, and what explains the choices that voters make. Since its inception, the CCES has involved more than 100 different research teams and hundreds of faculty and student researchers, and it has conducted interviews with over 300,000 American adults. The data from this project are used widely by researchers, journalists, and members of the public to understand American elections and public opinion. The 2020 Cooperative Election Study is developed by a consortium of research teams. Each research team that wishes to be involved in the project purchases a 1,000-person sample survey from the same firm. Each individual team determines half of the questions on its survey. The other half of the content (Common Content) is created by a design committee, drawn from the participating teams. Common Content consists of questions that every team would like to measure or questions that are of broad interest and require a very large sample. The project, thus, fields as many surveys as there are teams and also produces a single large sample survey that consists of the Common Content. The survey will be fielded over the Internet, with samples constructed to be nationally representative. Each team will receive the data from its own 1,000-person survey and a dataset consisting of the 50,000+ observations from the Common Content survey. Survey data are validated using voter validation and through comparisons of state level election results to the survey results from the subsamples for each state.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
