How the area is computed
The area shown is everything you can reach from the address within the chosen time, by car or on foot — computed on the real road network (IGN's BD TOPO, via the Géoplateforme public service). Inside it, we add up the real population (INSEE 200 m grid cells) and count your competitors one by one (OpenStreetMap). As close to the ground as it gets — never by whole town.
FAQ
What is a catchment area?
The territory most of a shop's customers come from. It is approximated by travel time: 5–10 minutes for convenience retail, 15–20 for mid-size stores, 30 for destination businesses.
Does this replace ODIL?
ODIL, INSEE's free tool, closed in 2021. This one picks up the need: catchment area plus public data for the zone, free and without sign-up.
How precise is it?
Travel times use the official road network. Inside the zone we count the real population (INSEE 200 m grid) and competing businesses (OpenStreetMap) — to the grid cell and the shop, not whole towns.
