If this map was the percentage of banks that went bankrupt, that would eliminate the base rate issue that some states have far more banks.

But I suspect Georgia’s issue would remain, even as a percentage. It’s banks were all smaller, which I suspect would make them more susceptible to failure. But it would be interesting to see that map to see if it is true.

As you suggest, dollars might be another way, or number of accounts (to level out the impact of wealth differences across regions).
