During decades, register data covering the total Danish population from cradle to grave have been collected. Most of this information has been collected for administrative purposes. However, Danish legislation allows for researchers to utilise data for research of general relevance and importance.

Based on the many and unique Danish registers, researchers working at NCRR offer expertise on all aspects of population-based epidemiology. This involves, e.g., legislative and ethic aspects of handling data, data management, security and implementation of epidemiological research. Upon appointment, researchers at NCRR offer advisory and practical support on register-based research, and are happy to participate in research collaboration with Danish and international colleagues.
