Time until next new county

[mileslunn]

Does eliminated count?  Kalawao county, Hawaii likely disappears in next 20 years as is an ex leper colony where no new people can move to, but those there can live remaining lives and it was late 60s they banned new people moving so people living there must be getting pretty old.  Once last person dies there I suspect it gets dissolved.  For elections I suspect they may not include in future elections within a decade just to keep vote secrecy since if number of residents too small it would be known who voted what.  I believe most states with precincts combine with others if too few votes to maintain privacy.

As for new ones, that is hard to say but lots of possibilities.  California has lots of really large ones not just in area but population too so splitting some of those would make sense.  Nevada & Arizona have large ones too but most asides largest metro areas are fairly sparsely populated so makes less sense to split them.
