Strengths & weaknesses — by weighted effect

▲ Catchment 84 — 48,317 aged 18-64 + 91,574 workers = 139,892 over 12.57 km2 = 11,132/km2
▲ Capture 81 — 1,370 residents + 3,087 workers, demand within 500 m against every competitor within 3 km
▲ Income 83 — 26,880 EUR against 22,380 nationally, median of 23 IRIS within 2 km
▼ Saturation 34 — 18 clubs / 70,714 residents = 25.45 per 100k against 11.01 nationally
▼ Competition 45 — 0 genuine gym floors and 2 other sports sites within 500 m, weighted by substitutability and price tier

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 21 gym floors and 23 other sports sites weigh 23.0, not 44.

4 rival(s) within 1 km when this club opened, 8 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). 6 nearby site(s) have no usable opening date and are not in either count.

Access — straight-line distance, GTFS

Nearest tram
Aimé Delrue — 747 m

Gare de l'État — 161 m
Counted footfall
Rezé Pont Rousseau — 1579 m, 206,368 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.

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.
