After the disbanding of the short-lived
Sunderland Albion, Sunderland became the only professional football club in
Sunderland, an urban area with a population of 335,000 as of 2011, and the
21st most populous urban area in the United Kingdom. Sunderland was also the largest and most successful of the four professional teams in
County Durham (alongside,
Gateshead A.F.C.,
Darlington and
Hartlepool United), until the town became part of the newly formed county of
Tyne and Wear in 1974. In contrast to teams in London and the North-West, Sunderland benefited historically from a large and relatively uncontested
catchment area far beyond the boundary of the town itself, incorporating areas such as
South Shields,
Durham,
Chester-le-Street,
Consett,
Seaham and
Bishop Auckland. Areas north of the
River Tyne traditionally fell within the catchment of
Newcastle United. Sunderland's attendances typically reflect their status as a one-club city with a large traditional catchment area. Despite a long period with relatively little success, Sunderland held the third highest average attendance in the country in the
2000–01 season with 46,791 fans. A 2019 survey by the
International Centre for Sports Studies (CIES) showed that over between 2013 and 2018, Sunderland recorded the 38th highest average attendance in world football with an average of 39,249 fans at the
Stadium of Light. Sunderland's average attendance were higher over that period than perennial title challengers such as
Juventus FC in Italy and
FC Porto in Portugal. Despite relegation from the
Premier League in 2017 and subsequent relegation from
The Championship at the end of the 2018 season, Sunderland continued to record high attendances. Sunderland broke the
League One division attendance record on 26 December 2018 in a match against
Bradford City with a total of 46,039 fans; it was the largest crowd outside of the Premier League that season, a feat repeated on 6 May 2022 when 44,742 watched a game v
Sheffield Wednesday. Sunderland's average attendance of 32,157 in the
2018–19 season was an English third-tier record and the largest average attendance outside of the Premier League. ==Nicknames==
