According to organisers the attendance figure for the 2015 tournament stands at 626,822 across 24 games. However, that number accounts for the same attendance repeated for two games held one after another at the same venue, potentially doubling the real amount.

All of the first two group games of every competing nation have been part of two games back-to-back at the same venue with no single match options available to fans. The forced purchase for two games and one seat has been used to reflect two separate ticket purchases.

The LOC has set a target of 1.5 million ticket sales for the tournament. Half the games are double headers.

FIFA confirmed the practice is in place for the attendance figures of each game which has led to an inflated final figure for the tournament.

"A ticket grants access for both games of a double header and given that it can be difficult technically to check how many persons were in the stadium per game, the total number of tickets issued is counted for each game," a FIFA spokesperson said.
