I don't believe that such an aviation hostile country as the UK has 30,000 pilots with a license that is in force.
The Centre of the Aviation Universe is North America. In addition to the large US number already quoted, Canada has 40,000 PPL or higher pilots licenses in force for a pop of around 36 Million. I would wager that the combined US/Canada total is larger than the rest of the world put together.
