Strengths & weaknesses — by weighted effect

▲ Competition 100 — 0 genuine gym floors and 0 other sports sites within 500 m, weighted by substitutability and price tier
▲ Income 100 — 33,090 EUR against 22,380 nationally, containing IRIS (no IRIS centre inside the radius)
▼ Catchment 4 — 903 aged 18-64 + 124 workers = 1,027 over 12.57 km2 = 82/km2
▼ Capture 8 — 1,124 residents + 69 workers, demand within 2 km against every competitor within 3 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.

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 0 other sports sites weigh 1.4, not 2.

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

1 when it opened, 2023-11-15 → 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).

Access — straight-line distance, GTFS

Nearest rail
Ponthierry - Pringy — 3494 m
Nearest bus
Brinville — 280 m
Counted footfall
PONTHIERRY — 3496 m, 128,801 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.

Published at commune level (IRIS 774350000). 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.
