Home / Fitness & recreational sports centers / Michigan / Macomb County, MI
How many gyms exist per person present — residents plus daytime workers — by ZIP code, compared with the U.S. average. Establishment data: Census ZBP 2023. Population: ACS 2024 5-year. 41 ZIP codes analyzed.
Includes: Gyms & fitness centers · CrossFit boxes · Boxing, martial arts & dance studios · Recreational sports centers. Counted together because official statistics use one 713940 code.
Why a range: Census does not publish a ZIP-by-industry count when that ZIP has 0–2 businesses. 26 ZIP cells in this county are withheld, 21 of them with residents. Each could hold 0, 1, or 2 businesses: counting them all as 0 gives the low end, counting them all as 2 gives the high end — the data cannot say where the truth sits. The density range uses only the populated cells, since ZIPs without residents are excluded from per-person rates. How ranges work
71 gyms are counted in Macomb County — 0.7 per 10,000 people present (residents + daytime workers), 67% of the U.S. rate of 1.0.
On the comparable ZIP set (ZIPs with a published count in every year), the total has risen 41% between 2015 and 2023 (22 → 31). That set is smaller than today's county total. 2020–2021 were pandemic-distorted, and Census rounds counts, so small moves are within noise.
Measured supply density is highest in 48315 (Utica), 48082 (Saint Clair Shores), 48026 (Fraser) — well above the national rate. On measured density alone, the lowest-density residential ZIPs with a published count are 48044 (Macomb), 48035 (Clinton Township), 48042 (Macomb).
BLS QCEW puts the latest county-wide count (2026 Q1) at 69 establishments, the freshest available signal.
Measured density: Macomb County sits at 67% of the U.S. rate for gyms. 21 ZIPs with population have no published count (each 0–2 businesses), so the true per-capita rate is between 67% and 107% of the U.S. rate. Why. The highest measured density is in 48315 and 48082; the lowest measured density is in 48044 and 48035.
This is a supply-side read: it counts existing gyms and the people present, not foot traffic, income, rent, or whether locals want more. Treat low density as a question to check, not an answer.
Macomb County had an estimated 886,175 residents on July 1, 2024 — 0.7% more than in 2020 (+5,881). In the latest year it gained 6,904 people: births minus deaths −295, international migration +5,651, domestic migration +1,588. Components are published separately and may not sum exactly.
329,207 jobs were located in the county in 2021 (−3.8% since 2019), and 383,709 employed residents lived there (−7.0% since 2019). LODES counts wage and salary jobs covered by unemployment insurance plus federal jobs; it excludes the self-employed and military, and counts jobs rather than unique people. 2019→2021 spans the pandemic, so read it as one change, not a trend. The 2022 file for this state is not usable, so 2021 is the latest year shown.
Population and migration say whether the customer base is growing. They do not say whether people want another business of this type. Definitions and limits → · Full county detail →
ACS 5-year estimates for 2015–2019 and 2020–2024. Only ZIPs with at least 2,000 residents in both windows and a change larger than the survey margin of error (90%) are listed — small ZIPs move a lot on paper without a real signal.
Not shown. NES 2024 does not publish fitness and recreational sports centers (NAICS 71394); only the broader recreation group (7139) is available.

White dots are ZIP totals from the official Census count — the bigger the dot, the more gyms in that ZIP. They are aggregated, not individual shops. Turquoise dots are individual locations mapped in OpenStreetMap, shown only at street level; they are crowd-sourced and indicative, may be incomplete, and do not equal the official counts. Only the official ZIP totals feed the saturation index.
Number of gyms in Macomb County across 2015–2023, on a consistent set of ZIP codes present in every year — so changes are real, not ZIP-boundary artifacts. 2015/2018 are pre-pandemic baselines; 2020/2021 are COVID-distorted.
Click a column header to sort. Index = gyms per 10,000 people present (residents + 0.5×workers) ÷ the U.S. average. 100% = exactly average.

Open vacancy data (actual empty units) is only published by some cities; where it exists we show it directly. Listings above are third-party.
Census withholds some ZIP-by-industry cells to protect small businesses. 0–2 means the cell was not published (Census publishes industry counts only at 3+ per ZIP), so the ZIP is left unranked rather than counted as zero. ~ means the count is estimated from the broader industry group and can be off by a business or two.
When a data vintage changes or a section of this report is revised, we post it to a public update feed. No email address, no account, no tracking — and nothing is sent unless something actually changed.
Establishments. U.S. Census ZIP Code Business Patterns (ZBP 2023), NAICS 713940 — fitness & recreational sports centers (gyms). Counts establishments with paid employees. ZBP is published annually with a ~2-year lag.
Fresh county signal. BLS QCEW (quarterly) is newer than ZBP — 2026 Q1 shows 69 establishments county-wide for this industry. It cannot be broken down by ZIP.
Population. U.S. Census American Community Survey 2024 5-year ZCTA population (table B01003). Workers are the ZIP's total employment from the same 2023 ZBP file.
Demand ("people present"). Demand comes from residents and daytime workers: residents + 0.5 × workers. This is the single documented assumption in the model and can be tuned.
Index. index = (ZIP establishments ÷ ZIP demand × 10,000) ÷ the U.S. average for this industry (1.03 per 10,000 present). It is a supply-side density measure; it does not capture income, rent, tourism, or whether locals actually want more.
