Strengths & weaknesses — by weighted effect

▲ Catchment 58 — 3,121 aged 18-64 + 3,310 workers = 6,430 over 0.79 km2 = 8,188/km2

▲ Capture 57 — 1,341 residents + 697 workers, demand within 500 m against every competitor within 3 km

▲ Saturation 56 — 5 clubs / 24,283 residents = 20.59 per 100k against 11.01 nationally

▼ Competition 40 — 3 genuine gym floors and 0 other sports sites within 500 m, weighted by substitutability and price tier

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 58 weight 20%	500 m	6,430 people	74	3,121 aged 18-64 + 3,310 workers = 6,430 over 0.79 km2 = 8,188/km2
Catchment 58 weight 20%	2 km	20,793 people	47	13,857 aged 18-64 + 6,936 workers = 20,793 over 12.57 km2 = 1,655/km2
Competition 40 weight 15%	500 m	2.40 wt	25	3 genuine gym floors and 0 other sports sites within 500 m, weighted by substitutability and price tier
Competition 40 weight 15%	2 km	5.02 wt	50	5 genuine gym floors and 3 other sports sites within 2 km, weighted by substitutability and price tier
Capture 57 weight 20%	500 m	2,038 people	67	1,341 residents + 697 workers, demand within 500 m against every competitor within 3 km
Capture 57 weight 20%	2 km	5,002 people	50	3,788 residents + 1,214 workers, demand within 2 km against every competitor within 3 km
Saturation 56 weight 15%	500 m	not measured	—	catchment of 5,198 residents is below the 10,000 needed for a density measure to mean anything — one club would move it by 1.7 LQ
Saturation 56 weight 15%	2 km	LQ 1.87	56	5 clubs / 24,283 residents = 20.59 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 58 weight 10%	500 m	0.99×	63	22,150 EUR against 22,380 nationally, median of 2 IRIS within 500 m
Income 58 weight 10%	2 km	0.96×	55	21,570 EUR against 22,380 nationally, median of 6 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	3	0	2.40
500 m – 1 km	2	1	2.30
1 – 2 km	0	2	0.32
2 – 3 km	1	0	1.00
Within 3 km	6	3	6.0 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 3 other sports sites weigh 6.0, not 9.

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

7 when it opened, 2026-09-01 → 7 today, 0 arrived since

7 rival(s) within 1 km when this club opened, 7 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). 1 nearby site(s) have no usable opening date and are not in either count.

Access — straight-line distance, GTFS

Nearest rail: Voiron — 107 m
Nearest bus: Voiron, FRERES TARDY — 37 m
Counted footfall: Voiron — 107 m, 1,651,235 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	5,198	6,618	43.8	3,121	60%
1.0 km	11,595	3,691	45.3	6,646	57%
2.0 km	24,283	1,932	43.9	13,857	57%
3.0 km	31,190	1,103	43.6	17,850	57%

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: €22,820 a year, per consumption unit
Poorest tenth: below €12,230

Poverty rate: 16.0% of households below 60% of the national median

Published at iris level (IRIS 385630105). 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.
