Do you know how many people are called Daisy in Wiltshire?
(Don't include cows)

Do you know how many pigeon fanciers there are in Belgium?
(No, I don't know what one is)

Do you know the number of allotment holders in the UK?
(330,000)

I don't know the first one but I've discovered answers to the other two from the rice show.

You can become part of the show by submitting a stat to be turned into grains of rice. However, you need to be able to back your stat up with information...
