Question: The 1953 Auburn Tigers football team marked the 21st season as a member of an American college athletic conference that is headquartered in Birmingham Alabama, and has how many teams?
Context: The Southeastern Conference (SEC) is an American college athletic conference whose member institutions are located primarily in the Southern part of the United States.  Its fourteen members include the flagship public universities of ten states, three additional public land grant universities, and one private research university.  The conference is headquartered in Birmingham, Alabama.  The SEC participates in the National Collegiate Athletic Association (NCAA) Division I in sports competitions; for football, it is part of the Football Bowl Subdivision (FBS), formerly known as Division I-A. The 1946 Auburn Tigers football team represented Auburn University in the 1946 college football season.  It was the Tigers' 55th overall and 14th season as a member of the Southeastern Conference (SEC).  The team was led by head coach Carl M. Voyles, in his third year, and played their home games at Auburn Stadium in Auburn, the Cramton Bowl in Montgomery and Legion Field in Birmingham, Alabama.  They finished the season with a record of four wins and six losses (4–6 overall, 1–5 in the SEC). The 1993 Auburn Tigers football team represented Auburn University in the 1993 NCAA Division I-A football season.  Under first-year head coach Terry Bowden, the team went undefeated with a record of 11–0 and finished #4 in the AP Poll.  Due to NCAA probation, Auburn was banned from TV and post-season play, and suffered reduced scholarships.  The post-season ban prevented Auburn from playing the SEC Championship and a bowl game.  Nonetheless, Auburn was the only major college football team to finish the season undefeated.  The National Champions Foundation recognized Auburn as one of its 1993 national champions, however Auburn University only formally recognizes championships for the 1957 Auburn Tigers football team and 2010 Auburn Tigers football team seasons, although the official website for Auburn athletics does highlight the 1993 team. The 1964 Auburn Tigers football team represented Auburn University in the 1964 college football season.  It was the Tigers' 73rd overall and 31st season as a member of the Southeastern Conference (SEC).  The team was led by head coach Ralph "Shug" Jordan, in his 14th year, and played their home games at Cliff Hare Stadium in Auburn and Legion Field in Birmingham, Alabama.  They finished with a record of six wins and four losses (6–4 overall, 5–3 in the SEC). The 1912 Auburn Tigers football team represented Auburn University (then called the Alabama Polytechnic Institute) in the 1912 college football season.  It was the Tigers' 21st season and they competed as a member of the Southern Intercollegiate Athletic Association (SIAA).  The team was led by head coach Mike Donahue, in his eighth year, and played their home games at Drake Field in Auburn, Alabama.  They finished with a record of six wins, one loss and one tie (6–1–1 overall, 4–1–1 in the SIAA). The 1962 Auburn Tigers football team represented Auburn University in the 1962 college football season.  It was the Tigers' 71st overall and 29th season as a member of the Southeastern Conference (SEC).  The team was led by head coach Ralph "Shug" Jordan, in his 12th year, and played their home games at Cliff Hare Stadium in Auburn and Legion Field in Birmingham, Alabama.  They finished with a record of six wins, three losses and one tie (6–3–1 overall, 4–3 in the SEC). The 1953 Auburn Tigers football team represented Auburn University in the 1953 college football season.  It was the Tigers' 62nd overall and 21st season as a member of the Southeastern Conference (SEC).  The team was led by head coach Ralph "Shug" Jordan, in his third year, and played their home games at Cliff Hare Stadium in Auburn, the Cramton Bowl in Montgomery and Ladd Memorial Stadium in Mobile, Alabama.

The 1944 Auburn Tigers football team represented Auburn University in the 1944 college football season.  It was the Tigers' 53rd overall and 12th season as a member of the Southeastern Conference (SEC).  The team was led by head coach Carl M. Voyles, in his first year, and played their home games at Auburn Stadium in Auburn, the Cramton Bowl in Montgomery and Legion Field in Birmingham, Alabama.

The 2005 Auburn Tigers football team represented Auburn University in the 2005 NCAA Division I-A football season.  Despite having four starters from the 2004 team selected in the first round of 2005 NFL Draft, Auburn finished the season with a 9–3 record, including a 7–1 record in the Southeastern Conference.  The Tigers shared the SEC Western Division championship with LSU, but because the Bayou Bengals defeated Auburn 20–17 in overtime on October 22, the Tigers did not advance to the SEC Championship Game.  Head coach Tommy Tuberville became only the third Tigers coach to lead Auburn to a fourth consecutive win over arch rival Alabama when the Tigers defeated the Crimson Tide 28–18 at Jordan–Hare Stadium on November 19.  Auburn finished the season ranked #14 in both the Coaches Poll and AP Poll, with a #13 consensus ranking.
