The Roper Center moved in 2018 to create a collection of surveys produced via recently developed methods, when accompanied by disclosure adequate to allow an informed assessment of these methods by the research community. These materials are housed in a separate collection from the Center's existing archive of surveys produced via longstanding methods.
Data collected via longstanding methods have been subjected to many decades of detailed investigation. The Center is establishing its collection of data obtained via recently developed methods to encourage the same level of scholarly assessment of these studies.
The archive defaults to a search of the longstanding methods collection. Researchers can then choose to search the newly developed methods collection as an option.
The new policy also includes the creation of a Roper Transparency Score for all new data acquisitions, in both collections. See more on the Center's new transparency and acquisitions policy here.
