Comparisons with their own page

227 pairs of neighbouring counties, each in the national top 200 by population, have a permanent page rather than a tool state. Those are the pairings people actually look for: two counties in one metro area, sharing a border, where the difference is a real decision.

Every county page also links directly to the comparisons available for it.
