Which country has the most cheats?

[jamz]

Myself, jamz, rofl, Shield, Optic, Jason, Andy, tipper and Aekom are the only guys from the UK I know who play AC o_0

You're well off with the total number off British players. Aside from missing about seven regular ladder-server players, the majority are the ones who really keep this game going; the mass of newbs, noobs, and casual players who bulk up the pubs and produce the occasional gem. This goes for every country.

...Just to clarify these stats are just those who were blacklisted for cheating or as a whole?

...a collation of actual Central blacklist additions for cheating...

Cheats only.

Here are the player numbers for January and February of this year. It's probably very inaccurate, since it's extremely hard to identify individuals.
Again, click for bigger:

I've only gone as far as covering every country that was on the first chart. There were 74,660 connections in total from January 1 to February 29.

Going back to the original chart, here's the data after dividing the number of cheats by the player population. Brazil is now slightly worse than the US, but New Zealand and Austria have twice as many.
Sorry about the colours; I got bored.
