Trosa Municipality



Trosa Municipality (Trosa kommun) is a municipality in Södermanland County in southeast Sweden. The municipality consists of the localities of Vagnhärad, Västerljung, Stensund, Sund and the town of Trosa. The seat of the municipality is located in the town of Trosa.

The present municipality was created as recently as 1992, when Nyköping Municipality, which Trosa had been a part of since 1974, was split in three parts.

The municipality borders to Nyköping Municipality, Gnesta Municipality, and in the north to Södertälje Municipality in Stockholm County.

Tourism
During the summer, the municipality sees its population of 14´000 (2021) increase fourfold. This is mostly due to people living in the Stockholm area that, during the summer, move to their holiday cottages in the municipality. Being close to Stockholm, the municipality is a favourite amongst tourists from abroad. The well-equipped harbour and Trosa's archipelago also attract many pleasure boats from both Sweden and the other countries bordering the Baltic Sea.

Elections
The table below shows the results of the parliamentary (Riksdag) elections for Trosa municipality since the inaugural election under its current entity in 1991. For the period 1991 to 1998, the exact numbers of the Sweden Democrats were not published by the SCB due to the party's small size nationally.
