Data documentation

Economic, social and contextual data

The 'Project database NCRR / CIRRAU' contains economic, social and contextual data from the registers of Statistics Denmark for the years 1980 and onwards or whenever data are available in specific registers.

These data may be extracted for defined study populations and placed in separate projects on one of the CIRRAU servers.

CIRRAU’s data managers set up documentation for all these variables in Danish and English. Links to this documentation, as well as detailed documentation for key variables (UK), may be found in the boxes below.

NOTE: If you need data from the Register of Medicinal Product Statistics, you apply for them through Statistics Denmark!

You may also look up documentation for the data on Statistics Denmark's homepage: "Højkvalitetsdokumentation" and "Registeroversigt" (DK).

The entire Danish population now has associated geocodes, complete from 1978 and onwards.

Version 1: Some researchers are already working on these data, where 95.6% of the Danish addresses were geocoded. The main reasons for incomplete data for earlier years are missing house numbers in the Danish Civil Registration System (CPR) and closed-down streets / roads.

Version 2: An improved set of geocodes includes 99.2% of Danish addresses.
