2000–present
In 2011 Siuntio, together with the municipalities of
Karjalohja,
Sammatti and
Nummi-Pusula, decided to merge with the city of Lohja starting in 2013. The decision was made following encouragement from the Finnish State to merge smaller municipalities together. The goal was to create larger administrative areas to eventually cut costs. However, the decision caused a conflict between the Siuntio political parties, which also divided the population. After several unclear negotiations, Siuntio failed to deliver any kind of answers and therefore was cut out of the merge with Lohja.
In 2018 Siuntio joined the
Helsinki Regional Transport Authority, securing good public transportation connections to
Helsinki sub-region.
