May 31, 2023: The Norwegian Cause of Death Registry profile has just been added

This registry collects data on deaths by age, sex, cause, place of death, and place of residence for Norway. It contains digitized cause of death data dating back to 1951. Electronic death certificates were introduced in 2018, and electronic delivery is mandatory since January 1, 2022. The registry collects death certificates for all deaths that occur in the country, including deceased who are not registered as inhabitants of Norway. It also registers the deaths of Norwegians who die abroad.
