Coverage. This page aggregates only the 11 Maryland 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 gyms 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 gyms may simply lack foot traffic, retail space, or demand. Use the ranking to find where to look, then verify locally.

BizGapMap — free, no-login small-business saturation reports for major U.S. counties. Built entirely from public U.S. Census, BLS, and IRS data (ZBP 2023, ACS 2024 5-year, PEP 2024, LODES, QCEW, IRS SOI). No forecasts, no revenue guesses — withheld cells are marked, and the few derived counts are labelled as estimates.
