Mappings of municipalities to other region types for history data

[jukop]

It would be useful in many cases to have mappings of municipality -> region and municipality -> subregion(seutukunta) from years much earlier than now. E.g. register-based data from HILMO care register contains municipality data from early 1970s, while currently geofi contains mappings for the 2013-2020.

I wonder if some resource/database already holds the borderline data of municipalities for 1970/1972-2012. Personally I had to use data from here in my past study: Kuntaliitokset wikipedia.

For weighting the study data with population data the borderline data are not necessarily needed so it would be useful to have more rough data (=no borderlines) available as well. That kind of mapping tables could be build based on the link I provided.
