Coverage. This page aggregates only the 3 Maine 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 convenience stores and the people present, not foot traffic, income, rent, or whether locals want more.

Low measured density is not evidence of opportunity. A county with few convenience stores may simply lack foot traffic, retail space, or demand. Use the ranking to find where to look, then verify locally.
