Jystic J?

I’m just filling in part of the MPS (monthly profit statement), and had to put in the UK population. The only thing we have is the census stats from 2001 so put that figure in. My work colleague asks me ‘What would the population be for this year?’ adding, “You should know”.
I should?
Apparently I know these kinda things?!?!?
Btw they actually have a budget figure for the population as well!?!!? We’re way behind.
Go figure!
