How fast is fastest?

Harry Shannon

I was listening to CBC radio last week, and heard someone claim that cricket is the fastest-growing sport in Ontario.  Maybe it was in Canada, but that’s not relevant to my point here.

My point is that the term fastest-growing is really meaningless, or at best misleading.  There are about a million registered soccer players in Canada.  Compare that with 15,000 registered to play cricket.  If the number of soccer players increased by half a million, that would be a 50% increase.  If the number of cricket players went up by 15,000, that’s a 100% increase.

So if you look just at the percentages, you’d argue that cricket is growing faster.  But the absolute increase in soccer players would be more than 30 times as many.

The lesson: remember the denominator.  If you start from a small number, even a small increase will be a big percentage increase.
