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 0 gym floors and
0 other sports sites weigh 0, not
0.
Competition since opening — gyms within 1 km, by the year they opened
1when it opened, 2026-09-07→1today, 0 arrived since
1 rival(s) within 1 km when this club opened, 1 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).

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

Published at commune level (IRIS 628490000).
An IRIS is a neighbourhood of roughly 2,000 people; a commune can be a whole town. The level
travels with the figure, so a town's median is never read as this street's.

Officers — company representatives on file

Legal representatives, not shareholders. France closed public access to the beneficial-ownership
registry in July 2024, so who owns the company is not obtainable from open data.
Filed accounts — INPI, the keyed annual accounts
Revenue

Net result
not filed
No keyed accounts in INPI's feed for this company. Absence means unfiled, not zero — most
small French companies file late or not at all.
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.
Location Score model 3.1.0,
computed 2026-10-17.
