What is the average attendance of a boxing match?

The largest outdoor boxing attendance record was set on Feb 20, 1993 in Mexico City. A reported 136 274 spectators filled Estadio Azteca to watch a then unbeaten Julio César Chávez against Greg Haugen in a WBC Light Welterweight title match.

The largest indoor attendance was in 1978 when Muhammad Ali fought Leon Spinks in at the Louisiana Superdome. That crowd was 63 315.
