To examine the relationship between HA and crowd density, city and same-stadium derby matches were ranked by the number of spectators in the stands held before the Covid-19 pandemic. Three ranks (categories) were allocated for city derbies: up to 1000 spectators, between 1000 and 10000, and more than 10000 spectators. There were two ranks for same-stadium derbies: under 10000 and over 10000. Data were obtained at four websites: uk.soccerway.com, www.transfermarkt.co.uk, www.bundesliga.com,www.soccer365.ru. In
