Yeah, probably a job for De Moivre's equation. I heartily recommend this chapter on it, covers similar geographical effects: http://press.princeton.edu/chapters/s8863.pdf

Stability is a great way to counter this effect. If a county goes up and down the cancer rate chart then it's probably statistical noise. However, if it's steadily at the top every decade for 50 years that's likely to have an cause. Even if it's just an older than normal population.

Just finished reading this chapter - a really awesome recommendation, I'll probably buy the whole book. Thanks!
