Blocs

This lists the relative strength of the socialist and centre-right blocs since 1973, but parties not elected to the Riksdag are inserted as "other", including the Sweden Democrats results from 1988 to 2006, but also the Christian Democrats pre-1991 and the Greens in 1982, 1985 and 1991. The sources are identical to the table above. The coalition or government mandate marked in bold formed the government after the election. New Democracy got elected in 1991 but are still listed as "other" due to the short lifespan of the party. "Elected" is the total number of percentage points from the municipality that went to parties who were elected to the Riksdag.
