Home Advantage Across Sports (1970s to 2020s)Home win % has fallen in every major sport over five decades

Home win % tracked across six decades for five major sports: Soccer, NBA, NFL, NHL, and MLB. All five show a steady decline from peak levels in the 1970s toward near-parity. Soccer falls furthest (63.2% to 54.9%); MLB was lowest throughout (55.8% to 53.6%). A legend panel annotates each sport's total percentage-point drop.

Source & accuracy

This home advantage across sports is an editorial illustration built to represent the concept accurately. Where it shows figures, they are typical or representative values chosen to make the relationship clear, not a single underlying dataset. The diagram and its explainer are reviewed and maintained centrally, and updated over time as understanding improves.

Ice hockey's strongest home effect, basketball's modest one

Home win rate varies across sports, with NHL teams winning about 55% of home games, NFL teams 57%, NBA teams 58%, and MLB teams 54%. Basketball's higher home rate is partly offset by neutral-court tournaments (playoffs don't always favor the higher seed), while hockey's roaring home crowds and travel fatigue may amplify the effect. Baseball's lower rate reflects the sport's lower variance, where individual performance dominates venue effects.

Crowd noise matters most in close games

The home advantage is strongest in tight matches where communication and split-second reactions matter. In hockey and basketball, the crowd's ability to disrupt audible calls and unsettle opponents compounds travel fatigue. In baseball, the dimensions and wind are fixed regardless of crowd size, reducing the lever arm for home advantage. The effect exists in all four sports but manifests through different mechanisms.
