Following national elections on September 14, figures released by Statistics Sweden show that Sweden's parliamentary members are on average two years younger than they were after the 2010 elections, when the average was 43.
"This is the youngest parliament ever in the history of Sweden's democracy," election statistician Richard Öhrvall told the TT news agency.
Sweden has seen the age of its politicians dropping steadily over the past few decades. Back in 1991, the average was over 50.
In 2014, the party with the youngest average age is the nationalist Sweden Democrats. Over one in three of its politicians are under the age of 35, with 39 the average age for elected representatives.

The worldwide average is 50 years old.
Sweden's largest party, the Social Democrats, has an average MP age of 47.
This makes them the oldest political group in the Riksdag and contradicts with their election promise to ensure 25 percent of its MPs are below the age of 35.
Currently only 16 percent of its national politicians are under 35.
Party Secretary for the Social Democrats Carain Jämtin said the party had taken "a clear step" but that there was still work to be done.
In the last election, the Social Democrats were significantly older, with just 9 percent under the age of 35.
