How to read Saint-Martin-d'Hères density?

High density reflects a mature commercial fabric, not necessarily saturated. Compare to national median (~50-80 etabs/1000 inhabitants urban) and look at creation dynamics (SIRENE 12m).

Why not indicate "saturated / not saturated"?

No universal ratio allows a verdict. Saturation depends on business, district, purchasing power (Filosofi income), and recent dynamics. NTYB gives the numbers, you keep the reading.

When does the per-inhabitant ratio not make sense?

For destination retail (car dealer, specialty store) which captures a catchment area larger than the town. Then catchment (vertical /chalandise/) is relevant.

"Business / inhabitant" ratio method

The pop/nb_etabs ratio per business is the most used saturation indicator. Common benchmarks: 1 bakery / 2 000 inhabitants (Observatoire Franchise), 1 pharmacy / 2 500 inhabitants (regulation for rural towns), 1 hairdresser / 750 inhabitants. Beyond the raw ratio, look at dynamics (creations / cessions BODACC).
