Geography
It is the eastern neighbour of Helsinki and western neighbour of Porvoo, located in the Uusimaa region. Other neighboring municipalities are Vantaa, Kerava, Tuusula, Järvenpää, Mäntsälä and Pornainen. There are two important road connections in the direction of Helsinki from Sipoo: Highway 7, known as the Porvoo Highway (part of E18), and Road 170, which is known as the Itäväylä on the Helsinki side. The once almost completely Swedish-speaking municipality is bilingual since 1953, a majority being Finnish speakers, due to migration from other parts of Finland since 2003. Today the Finnish-speaking majority stands at and the Swedish-speaking minority comprises about of the population. Sipoo appealed to the Supreme Administrative Court, but the court upheld the decision of the Council of State and the annexation took place on January 1, 2009. As Helsinki did not directly border Sipoo at any point, the city of Vantaa ceded the area lain between Helsinki and Sipoo to Helsinki in the process.
