Stockholm County or Region Stockholm held a regional council election on 9 September 2018 on the same day as the general and municipal elections.
[3] The Social Democrats supplanted the Moderates as the largest party.
[4] Previously, the Alliance parties had a majority since the 2014 regional elections, but losses to the Sweden Democrats necessitated the formation of a cross-bloc coalition with the Greens to gather a governing majority, as the Alliance parties wished to avoid relying on the Sweden Democrats.
[5] Stockholm Municipality was divided into six separate electoral wards (Södermalm-Enskede, Bromma-Kungsholmen, Norrmalm-Östermalm-Gamla Stan, Östra Söderort, Västra Söderort and Yttre Västerort) and its results were not counted as a unit.
These wards have in these lists been translated to English to shorten columns.
