Strengths & weaknesses — by weighted effect

▲ Income 100 — 25,840 EUR against 22,380 nationally, median of 1 IRIS within 500 m
▲ Competition 75 — 0 genuine gym floors and 0 other sports sites within 500 m, weighted by substitutability and price tier
▲ Saturation 72 — 3 clubs / 17,558 residents = 17.09 per 100k against 11.01 nationally
▼ Catchment 50 — 1,532 aged 18-64 + 262 workers = 1,795 over 0.79 km2 = 2,285/km2

Each parameter scores 0–100 on a stated line between named breakpoints, then the seven combine on their weights — renormalised over whatever was measurable, so a missing parameter dilutes nothing rather than counting as zero.

Each site is discounted by how substitutable its activity is for a gym and how far its price tier sits from a mid-market club — so 9 gym floors and 1 other sports sites weigh 9.2, not 10.

3 rival(s) within 1 km when this club opened, 4 now. The forecast uses the founding count: it measured better than averaging the field over the club's life (LOOCV 0.091 vs 0.106).

Access — straight-line distance, GTFS

Beaujoire — 1484 m

Potiron — 305 m
Counted footfall
Erdre Active — 2085 m, 54,569 travellers a year (SNCF)
Straight-line, not travel time: no free routing service covers France at this volume, so a stop 300 m away across a railway line reads the same as one 300 m along the street.

Adults 18–64 is the span members come from. A median age alone does not separate a student quarter from a family suburb, and those are not the same market.

Newest first. Accounts filed on time are the ordinary case; an insolvency, a receivership or a pledge over the business would appear here too, and none does unless it is listed above.
What this is. The Location Score is model output, computed from open data; it is not a measured fact and not a valuation. Registry facts — name, SIRET, NAF, address, opening date, officers, filed revenue — come from INSEE Sirene and the Ministère des Sports facility census. Population, age profile and income are INSEE (Filosofi 2021, 200 m grid and IRIS). Competitors are the active, genuinely-operating gym floors in this database. Distances are straight-line, not travel time.
