The Christmas Eve lighthouse in Trosa Archipelago

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^{[citation needed]}. 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.

Political blocks

The table below lists the relative strength of the socialist and centre-right blocks since 1991. Parties not elected to the Riksdag are included in "others" such as the Sweden Democrats (results from 1988 to 2006) and the Greens (1991). The sources are identical to the table above. The coalition or government mandate marked in bold formed the government after the election. The New Democracy party got elected in 1991 but are still listed under "other" due to the short lifespan of the party.
