And if you include the number of girls playing football just for fun, almost 1.5m are currently taking part in the sport.
And the number of schoolgirls playing has gone through the roof, with 40,000 more playing the game than 10 years ago.
Films like Bend It Like Beckham have made the game more popular, as has the first ever professional women's football team - Fulham Ladies.
