We encourage use of the CPR data and access will be provided for genuine research purposes. If you believe that the data would benefit your research, or you can contribute to the analyses of the data, please contact the administrators of the data at firstname.lastname@example.org. [Please put "SO-CPR Survey" in the Title or Subject heading of the message or it will be blocked] We require a brief statement on the proposed use of the data, method of analysis and likely output of results, e.g. publications and where. This is to ensure that the request for access is bona fide, and that there are no conflicts with any existing analyses, especially with current student projects. In some cases, we may team you with another analyst if we consider this will improve the results. A password to the data set will be sent once access is granted. We may also elect to send an extract of the data.
