Dataverse
CES responses are publicly available. The CES Dataverse is the go-to website to download various CES datasets. The CES Dataverse contains:
- Each year's common content survey data
- A "cumulative" dataset that stacks together each year's common content by standardizing the coding of the most common variables
- Team modules in even years (it is up to the team PIs to disclose odd-year modules)
