Source-derived summary

Södermanland County (Swedish: Södermanlands Län) is one of the 29 multi-member constituencies of the Riksdag, the national legislature of Sweden. The constituency was established in 1970 when the Riksdag changed from a bicameral legislature to a unicameral legislature. It is conterminous with the county of Södermanland. The constituency currently elects nine of the 349 members of the Riksdag using the open party-list proportional representation electoral system. At the 2022 general election it had 223,767 registered electors.

Electoral system

Södermanland County currently elects nine of the 349 members of the Riksdag using the open party-list proportional representation electoral system. Constituency seats are allocated using the modified Sainte-Laguë method. Only parties that reach the 4% national threshold and parties that receive at least 12% of the vote in the constituency compete for constituency seats. Supplementary levelling seats may also be allocated at the constituency level to parties that reach the 4% national threshold.

Prior to 1997 voters could cast any ballot paper they wanted though it had to contain the name of a party and the name of at least one candidate nominated by that party in the constituency.

Editorial analysis

Why this record matters

The phrase “swedish electoral constituency” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 26, 2026. The linked authority identifier is Q10688608. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1970, 2022 and 1997.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
