Announcing the 2018 Cooperative Congressional Election Study

March 1, 2018

There is power in numbers. Starting in 2006, a consortium of 39 universities came together to create the Cooperative Congressional Election Study, the first truly large-scale academic survey project aimed at studying the midterm Congressional elections.   The study has continued every year since.   Our joint efforts have produced national sample surveys in excess of 50,000 respondents for every recent federal election.   Professors Stephen Ansolabehere (Harvard University), Brian Schaffner (University of Massachusetts) and Sam Luks (YouGov) coordinate the CCES, which is administered by YouGov. The study has been supported by the National Science Foundation since 2010. 

We invite you to join this unique project for 2018.

Design

We plan a national sample stratified by state and type of district, which permits the optimal study of congressional and state races and state politics, as well as the Presidential election. The 2018 survey will be conducted on the Internet and consist of a 20-minute pre-election wave and a 10-minute post-election wave.

Content

Half of the survey content will be Common Content, administered to all survey respondents, and half of the content will be team content, administered to 1,000 respondents for each team. The CCES Planning Group will design the Common Content. Common Content consists of a battery of questions asked of all respondents to capture commonly asked questions, such as vote choice, as well as a handful of items for which it is uniquely advantageous to have a very large sample. Each team will design its own team content.

Deliverables

The project will deliver a 1,000-person survey covering your team’s content; a Common Content survey that consists of a subset of questions asked of all subjects; and the validated vote for most subjects in the sample, where available. Data will be embargoed for the private use of those participating teams for a term of one year after the delivery of the survey.

Cost

Thanks to funding we expect to receive from the National Science Foundation, the cost of the study is $13,000 per team for a 1,000-person sample. Depending on sample constraints, it may be possible to purchase additional cases. To join the study, please contact Sam Luks (sam.luks(at)yougov.com) or Marissa Shih (marissa.shih(at)yougov.com) at YouGov. Note that there is a limit on the total number of teams that can participate in this study, so if you are considering joining, please let us know as soon as possible.
