In 1950 the Nikolai Rural municipality was dissolved. One part formed the then City of Oxelösund, one of the last newly created cities of Sweden. The rest of Nikolai was incorporated into the neighbouring City of Nyköping. In 1971 the city became a unitary municipality without addition of territory.
Still marked by its industrial past, the politics was historically dominated by the Social Democratic Party, and the industry by the harbour and iron works.
Geography
It covers a peninsula in the Baltic Sea, and borders by land only on Nyköping Municipality. With an area of 35.75 square kilometres (13.80 sq mi), it is one of Sweden's smallest municipalities.
No boundary changes. The Sweden Democrats' numbers were not listed by the SCB agency from 1988 to 1998 due to the party being out of contention for Riksdag entry.
This is a demographic table based on Oxelösund Municipality's electoral districts in the 2022 Swedish general election sourced from SVT's election platform, in turn taken from SCB official statistics.[17]
There is a strong income disparity between the four districts on the southern shore and the other three downtown districts. In comparison, the wealthier districts would all be among the upper-half earners in the more affluent Nyköping Municipality, while the lower three would be right near the bottom.[18] In total there were 12,125 inhabitants with 9,072 Swedish citizens of voting age.[17] The political demographics were 52.5% for the left bloc and 45.4% for the right bloc.[17] Indicators are in percentage points except population totals and income.
Oxelösund is a member of the Douzelage, a unique town twinning association of 24 towns across the European Union. This active town twinning began in 1991 and there are regular events, such as a produce market from each of the other countries and festivals.[19][20] Discussions regarding membership are also in hand with three further towns (Agros in Cyprus, Škofja Loka in Slovenia, and Tryavna in Bulgaria).
