A sea of Silver and Black at Azteca Stadium in November indicated a truth that the NFL backed up Thursday: Mexico gets excited over American football.

The Raiders-Texans game on Nov. 21, 2016 created a $45 million increase to Mexico City’s gross revenues, according to a study of the game’s economic impact commissioned by the NFL.

OK, so the Texans were a part of that, too. But with the NFL sending the Raiders back to Mexico City in 2016 for a game against the Patriots, it’s clear which team had more of an effect. Related Articles Raiders will return to Coliseum — and everybody ends up looking bad

The study, conducted by sports industry group Ernst and Young and announced Thursday by the NFL, used sources like the league’s post-event surveys of fans who attended the game and wider economic data on Mexico’s economy.

Among the 76,473 attendees to that Monday night game, more than 20,000 traveled from elsewhere in Mexico and nearly 10,000 visited internationally. Each of the latter spent more than five days in Mexico, on average, according to the study.

Total domestic and international tourist spending was $43 million, of which $32 million was incremental to the Mexico City economy, according to the study.

Another aspect were the 205,000 people who attended the NFL Fan Fest in Chapultepec Park and more than 55,000 who took part in other community events during game week.

Another data point could be added this year, if the NFL commissions a similar study. Could that trend toward an NFL franchise in Mexico City?
