As of today there have been 320 games completed of the 380 games in the 2020-21 Premier League season. There are slightly more away wins (125) than home wins (120). They are within 5% of each other. What makes this surprising is that it is well below what normally happens. If we take the 5 seasons from 2014-15 to 2018-19 then we find that home wins are 51% higher than away wins. Following basic estimation of excess deaths, we can attribute the excess of home wins over away wins to the presence of fans. Basic, but a good first approximation.
Below is the ratio of home wins to away wins (no draw/ties included) for this season and five of the previous six seasons. The 2019-20 season is excluded.
