The Tokyo Olympics were recently held one year ahead due to the corona pandemic and will be decided July 23 - August 8 next year.
World Athletics chairman Sebastian Coe says the decision means that athletes can do better planning and that it will be fairer for everyone.
"This is the best way to create justice as it can be uneven when it comes to competition events around the world with a view to traveling and border restrictions," Coe said in a press release.
Four Swedish athletes and a pedestrian have so far been Olympic-selected by the Swedish Olympic Committee: Daniel Ståhl, discus, Armand Duplantis, stake jump, Angelica Bengtsson, do, Kim Amb, spear, and Perseus Karlström, 20 km walk.
