Strengths & weaknesses — by weighted effect

▲ Saturation 100 — 4 clubs / 41,410 residents = 9.66 per 100k against 11.01 nationally

▲ Income 100 — 35,030 EUR against 22,380 nationally, median of 1 IRIS within 500 m

▲ Capture 62 — 4,788 residents + 4,275 workers, demand within 2 km against every competitor within 3 km

Nothing scores below the middle of its range here.

How the score was reached — seven parameters, five measured separately at 500 m and 2 km

Parameter	Where	Measured	Score	How it was arrived at
Catchment 60 weight 20%	500 m	2,456 people	54	1,090 aged 18-64 + 1,367 workers = 2,456 over 0.79 km2 = 3,128/km2
Catchment 60 weight 20%	2 km	52,023 people	65	24,995 aged 18-64 + 27,028 workers = 52,023 over 12.57 km2 = 4,140/km2
Competition 54 weight 15%	500 m	1.00 wt	58	1 genuine gym floor and 0 other sports sites within 500 m, weighted by substitutability and price tier
Competition 54 weight 15%	2 km	4.56 wt	52	4 genuine gym floors and 3 other sports sites within 2 km, weighted by substitutability and price tier
Capture 62 weight 20%	500 m	913 people	44	599 residents + 314 workers, demand within 500 m against every competitor within 3 km
Capture 62 weight 20%	2 km	9,064 people	75	4,788 residents + 4,275 workers, demand within 2 km against every competitor within 3 km
Saturation 100 weight 15%	500 m	not measured	—	catchment of 1,701 residents is below the 10,000 needed for a density measure to mean anything — one club would move it by 5.3 LQ
Saturation 100 weight 15%	2 km	LQ 0.88	100	4 clubs / 41,410 residents = 9.66 per 100k against 11.01 nationally
Fit — weight 10%	unit	not measured	—	no floor area recorded for this unit
Rental — weight 10%	unit	not measured	—	no rent or no floor area recorded
Income 100 weight 10%	500 m	1.57×	100	35,030 EUR against 22,380 nationally, median of 1 IRIS within 500 m
Income 100 weight 10%	2 km	1.13×	100	25,245 EUR against 22,380 nationally, median of 18 IRIS within 2 km

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.

Competitive field — every active gym and other sports site within 3 km

Band	Gym floors	Other sports	MCI weight
within 500 m	1	0	1.00
500 m – 1 km	2	2	2.46
1 – 2 km	1	1	1.10
2 – 3 km	2	4	3.20
Within 3 km	6	7	7.8 total

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 6 gym floors and 7 other sports sites weigh 7.8, not 13.

Other sports sites — 7 within 3 km, discounted by activity

3 rival(s) within 1 km when this club opened, 6 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). 5 nearby site(s) have no usable opening date and are not in either count.

Access — straight-line distance, GTFS

Nearest rail: Croix - Wasquehal — 619 m
Nearest bus: Pole Sportif — 402 m
Counted footfall: Croix - Wasquehal — 619 m, 5,990 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.

Catchment — INSEE 200 m population grid, Filosofi 2021

Ring	Residents	Per km²	Median age	Adults 18–64	Share of residents
0.5 km	1,701	2,166	38.8	1,090	64%
1.0 km	6,309	2,008	37.6	4,047	64%
2.0 km	41,410	3,295	38.9	24,995	60%
3.0 km	94,239	3,333	39	55,488	59%

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.

Household income — INSEE Filosofi 2021

Median: €23,980 a year, per consumption unit
Poorest tenth: below €12,410
Richest tenth: above €42,220
Spread: ×3.4 between them · Gini 0.272
Poverty rate: 13.0% of households below 60% of the national median

Published at iris level (IRIS 596460202). 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.
