NUTS 2016, in force 2018 to 2020 (EU No 2066/2016.) The only change in Finland in the NUTS regional classification on the NUTS 3 level was caused by the transfer of the municipality of Vaala from the region of Kainuu to that of North Ostrobothnia at the beginning of 2016. Then the regions of both Kainuu and North Ostrobothnia received new NUTS 3 codes. The new NUTS 3 codes are Kainuu, FI1D8, and North Ostrobothnia, FI1D9. Otherwise, the set of NUTS codes and nomenclature remain the same as in NUTS 2013 (in force 2015 to 2017).
The Swedish name of NUTS 1 level group Mainland Finland changed into Fastlandsfinland (previously Fasta Finland).
NUTS 2013, in force 2015 to 2017 (EU No 1319/2013). In Finland, the NUTS regional classification remains unchanged. Changes in administrative areas in 2013 to 2014 caused minor boundary checks on the NUTS 3 level (boundaries of regions 2013). These were changes in boundaries of regions caused by municipal mergers. Population changes caused by municipal mergers were so minor on the NUTS 3 level that the actual classification was not changed, that is, it stayed the same as NUTS 2010.
NUTS 2010, in force 2012 to 2014 (EU No 31/2011). The biggest change in Finland concerned the NUTS 2 regional division. Former Southern Finland was divided into two parts so as to form the new metropolitan area Helsinki-Uusimaa (FI1B), and the rest of Southern Finland formed an area of its own (FI1C). In addition, former Northern Finland and Eastern Finland merged into one region, which was called Northern and Eastern Finland (FI1D). After the changes, Mainland Finland (FI1) still had four NUTS 2 regions. On the NUTS 3 level, Finland lost one region, when Uusimaa and Itä-Uusimaa merged as regions in 2011 and now formed the new NUTS 3 region Helsinki-Uusimaa (FI1B1). However, it should be noted that changes in the NUTS 2 regional level caused changes to the set of codes and nomenclature on the NUTS 3 level as well.
