Highest counties

Rank 1 is the highest value, and for this measure a higher value is the worse outcome. “First” here does not mean best.

DuPage County leads reliably only from rank 2 downwards. Its estimate range overlaps those of the ranks above 2, which therefore cannot be separated from it at 90 % confidence.
