SLF-H

Strengths & weaknesses — by weighted effect

▲ Saturation 100 — 0 clubs / 17,497 residents = 0.00 per 100k against 11.01 nationally

▲ Competition 85 — 0 genuine gym floors and 4 other sports sites within 2 km, weighted by substitutability and price tier

▲ Capture 62 — 6,625 residents + 1,379 workers, demand within 2 km against every competitor within 3 km

▼ Catchment 39 — 484 aged 18-64 + 630 workers = 1,114 over 0.79 km2 = 1,419/km2

▼ Income 45 — 20,170 EUR against 22,380 nationally, containing IRIS (no IRIS centre inside the radius)

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 39 weight 20%	500 m	1,114 people	38	484 aged 18-64 + 630 workers = 1,114 over 0.79 km2 = 1,419/km2
Catchment 39 weight 20%	2 km	14,001 people	40	10,420 aged 18-64 + 3,581 workers = 14,001 over 12.57 km2 = 1,114/km2
Competition 85 weight 15%	500 m	0.30 wt	84	0 genuine gym floors and 1 other sports site within 500 m, weighted by substitutability and price tier
Competition 85 weight 15%	2 km	0.70 wt	85	0 genuine gym floors and 4 other sports sites within 2 km, weighted by substitutability and price tier
Capture 62 weight 20%	500 m	1,105 people	49	722 residents + 383 workers, demand within 500 m against every competitor within 3 km
Capture 62 weight 20%	2 km	8,004 people	70	6,625 residents + 1,379 workers, demand within 2 km against every competitor within 3 km
Saturation 100 weight 15%	500 m	not measured	—	catchment of 869 residents is below the 10,000 needed for a density measure to mean anything — one club would move it by 10.5 LQ
Saturation 100 weight 15%	2 km	LQ 0.00	100	0 clubs / 17,497 residents = 0.00 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 45 weight 10%	500 m	0.90×	34	20,170 EUR against 22,380 nationally, containing IRIS (no IRIS centre inside the radius)
Income 45 weight 10%	2 km	0.96×	53	21,470 EUR against 22,380 nationally, median of 5 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	0	1	0.30
500 m – 1 km	0	0	—
1 – 2 km	0	3	0.40
2 – 3 km	2	1	1.70
Within 3 km	2	5	2.4 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 2 gym floors and 5 other sports sites weigh 2.4, not 7.

Competition since opening — gyms within 1 km, by the year they opened

1 when it opened, 2026-10-01 → 1 today, 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). 2 nearby site(s) have no usable opening date and are not in either count.

Access — straight-line distance, GTFS

Nearest rail: Meulan - Hardricourt — 513 m
Nearest bus: Centre Commercial Vexin — 24 m
Counted footfall: MEULAN — 509 m, 223,157 validations a year (RATP)

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	869	1,106	42.8	484	56%
1.0 km	4,504	1,434	38.5	2,780	62%
2.0 km	17,497	1,392	37.6	10,420	60%
3.0 km	32,437	1,147	36.6	18,671	58%

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: €25,430 a year, per consumption unit
Poorest tenth: below €14,150
Richest tenth: above €42,750
Spread: ×3.0 between them
Poverty rate: 9.0% of households below 60% of the national median

Published at commune level (IRIS 782990000). 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.

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.
