Breaks

Some dwellings can be registered as empty in times when one resident moves out and another moves in.

Consistency of terminology or coding used during collection

There has been a slight change in the definition of dwellings in 2005. Before 2005, summer houses where not included even though there where residents registered as living there permanently.

Strengths: The survey covers all dwellings in Denmark. It is possible to link the database to other registers and the data can further be linked to information about moving patterns in the register BOPA. Weaknesses: Some of the information is dependent upon the residents reporting to the building and home register when buildings are renovated.
