How many people play soccer worldwide?

How to get close to this number

Reason from global reach. This is the most played sport on Earth, present in over two hundred national associations, but "plays regularly" is a much higher bar than "watches" or "has played". Regular participation across the whole world for the leading sport lands in the hundreds of millions rather than the billions.

The gap between watching and playing is what catches people. Billions watch football; a fraction of that number plays it regularly, because regular play requires a pitch, a team and free time that most adults do not have. Participation figures are always an order of magnitude below audience figures, for every sport.

The professional ratio in the explanation is the sobering one: roughly one in every two thousand players earns a living from it. That is the arithmetic behind every youth academy in the world, and it is worth having in mind when the sport is discussed as a career path — the base of the pyramid is enormous and the top is very small.
