Those following London's top flight teams have regularly been placed near the top of football fans' earnings lists and strong attendances at their games show they are prepared to cover the rising costs.
But the average figure from the survey makes the game more expensive as a live event than traditional premium rate entertainment such as West End theatre. It also puts London football in a higher price bracket than some top European leagues.
Nearly a third of those who took part considered the costs of watching games to be dear.Other findings included insights into the problem of hooliganism and racism at matches in the capital.
Welcoming the survey, Clarke said: "The more the authorities find out about people who keep the game going through their money, the better.
"It is good news that the Evening Standard is prepared to carry out this sort of important research."
A spokesman for the Football League said: "We are always interested to hear fans' opinions about the state of the game and look forward to having the opportunity to analyse this survey's results in greater detail."
