Will Georgia have more population than Ohio by 2030?

[Ban my account ffs!]

I would say so.  Between now and 2030 the proportion of those elderly and dying will increase more in Ohio than in Georgia.  By 2030 it could be that Georgia is still growing modestly while Ohio is shrinking.

Of course things can change.  There might be a rush back to the rust belt for some reason.

If the Republicans in the statehouse ever wake-up and smell the breeze we might get at least a small boost out of tapping into the state's wind energy potential, both in the Northwest and off-shore on Lake Erie.  It probably still wouldn't be enough to completely stem the tide of people fleeing from the Northern metros but it would be something positive.

Wind power won't provide any substantial population growth.  It might keep a handful of people from leaving.  But you're talking about hundreds of jobs... not the hundreds of thousands Ohio would need to keep ahead of Georgia.
