Researchers can use sensitive, restricted-access data in our Secure Research Data Centre at the University of Cape Town. These data include person- household - and institution-level variables that could make identification of respondents possible. They therefore need to be used by responsible researchers in a secure facility. Our secure centre has approved protected access repository status under the Open Science Framework. This collection shows what data is available and cites research publications based on the data in our secure centre. Applications to use the secure centre are available on our secure centre site https://www.datafirst.uct.ac.za/services/secure-data-services.
