# Cooperative Election Study ![CES](/sites/g/files/omnuum8901/files/styles/hwp_1_1__100x100_scale/public/cces/files/ces_logo_rgb.png?itok=4XGPweRV) ## Welcome! **PLEASE NOTE THAT OUR NEW WEBSITE CAN BE FOUND** [HERE](https://tischcollege.tufts.edu/ces)**.** The CCES is a 50,000+ person national stratified sample survey administered by YouGov. Half of the questionnaire consists of [Common Content](/book/common-content) asked of all 50,000+ people, and half of the questionnaire consists of Team Content designed by each individual participating team and asked of a subset of 1,000 people. In addition, several teams may pool their resources to create [Group Content.](/book/group-content) The survey consists of two waves in election years. In the pre-election wave, respondents answer two-thirds of the questionnaire. This segment of the survey asks about general political attitudes, various demographic factors, assessment of roll call voting choices, political information, and vote intentions. The pre-election wave is in the field from late September to late October. In the post-election wave, respondents answer the other third of the questionnaire, mostly consisting of items related to the election that just occurred. The post-election wave is administered in November. In non-election years, the survey consists of a single wave conducted in the fall.
