CIRRAU provides the data infrastructure to support and conduct research


CIRRAU provides the necessary and fundamental data infrastructure to support and conduct a large variety of register-based research projects ranging from intervention studies of vulnerable children and adolescents, through population-based genetic studies of mental disorders to nationwide population-based studies of a large variety of exposures, outcomes and consequences of outcomes.

The CIRRAU research database is one of the world’s most comprehensive datasets. It combining nationwide individual-level information on health, family, social, and economic factors with biological and genetic research data to support interdisciplinary population-based research.

CIRRAU provides a secure and comprehensive data infrastructure that constitutes the foundation for register-based analyses carried out in scientific programmes supported by the Lundbeck Foundation, TrygFonden, the EU, The Stanley Medical Research Institute, The Simons Foundation and NordForsk. By combining nationwide longitudinal register data with biological and other research resources, the infrastructure supports interdisciplinary studies of health, social, educational and economic outcomes across the life course.

Denmark: Unique opportunities for Danish register-based research


Danish authorities have collected records on the entire Danish population for decades. Most information has been recorded solely for administrative purposes. 

Examples of information available through the Danish registers include:

  • Demographics and whereabouts of each person
  • Information on family members
  • Health
  • Prescribed medicine
  • Income
  • Wealth
  • Social benefits
  • Bereavement
  • Education
  • Employment
  • Workplace

Danish legislation allows Danish researchers to utilize these data to conduct research of public relevance and importance. The research potential of these data is further enhanced by the possible linkage to collections of biological material.

The breadth, quality, and longitudinal nature of these data have made Denmark a leading country in register-based research. For many years, Danish researchers have utilized these resources to conduct high-quality register-based research and have published in various high-ranking scientific journals.
