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 4 gym floors and
1 other sports sites weigh 3.1, not

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 iris level (IRIS 442100102).
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.

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.
Location Score model 3.1.0,
computed 2026-10-17.
