Coverage. This page aggregates only the 12 Tennessee counties BizGapMap covers — not the whole state. Counts and the index reflect those counties. The aggregate index uses only ZIP cells Census published, so it is a lower bound. Density is a supply-side signal: it counts existing auto repair and the people present, not foot traffic, income, rent, or whether locals want more.
