Sweden held a general election on the 20 September 1970. This was the final general election being held before the municipal reform that cut the number of municipalities to below 290. This was the first unicameral Riksdag elected.
1970 was the final election where the postal votes were counted separately from the polling station votes in one unified count across municipalities. The exception to these results are those where the whole constituency was one municipality - namely Gothenburg, Gotland and Stockholm where all postal votes were automatically denoted as part of said municipalities.
Dalarna County was known as Kopparberg County at the time, but shared the same borders as in the 21st century.
Kopparberg County
There was a discrepancy of three votes between the Kopparberg County's official count (173,240 votes) and the municipality and post ballot-based list (173,243 votes). This difference accounted for 0.00173% of the overall vote and thus did not change any percentages.
The province of Skåne, later unified into one county, was divided into Malmöhus and Kristianstad counties at the time, also resulting in three separate constituencies, one for each county and a third for the metropolitan area of Öresund, that was part of Malmöhus.
Stockholm County was divided into Stockholm Municipality and the surrounding county of suburbs or more rural areas.
The later iteration of Västra Götaland County was divided into three separate counties and five constituencies in 1973. The three counties were Gothenburg and Bohuslän, Skaraborg and Älvsborg. Gothenburg/Bohus were divided into one constituency representing Gothenburg Municipality and one representing Bohuslän, whereas Älvsborg was divided into two constituencies, one in the north and one in the south. Skaraborg had one constituency for the whole county.
