A fan of Hammarby is referred to as a bajare or a hammarbyare. Hammarby has historically been regarded as a club with a mainly working-class fan base, due to its connection with the formerly working-class (but today gentrified) Södermalm district of Stockholm. Nowadays the club attracts fans from all parts of society. According to a 2016 poll, a large part of the club's fan base tends to support left-wing politics compared to those of their local rivals AIK and Djurgården. Hammarby has strong ties to Söderort, the southern part of Stockholm urban area. A 2012 poll showed that Hammarby was the most popular club in Söderort; 40 percent of the area's residents who had a favourite club chose Hammarby. Hammarby's training ground, Årsta Idrottsplats, is located in the district of Johanneshov, while some of the older youth teams still play at Hammarby IP in Södermalm.
