Merging organisations
Every year several municipalities merge. (On Jan 1th, 2018 we go from 388 to 380).

The number of organisations that is involved in a merge varies. In some cases involved organisations deprecate their old name and go forward with a new one. Sometimes one organisation is absorbed by another. Sometimes one municipality (and it's area) is split into many pieces that each merge with another municipality.
Some research needs to be done:
- How does this impact the statistics?
- What is impact on code / information models?
- What is impact on map?
