15 Minutes From Los Angeles, CA

Los Angeles is the canonical case study for why drive-time matters more than distance. A 5-mile straight-line radius can translate to a 12-minute drive at 10am and a 55-minute drive at 5pm, and any trade-area study that ignores this is effectively fiction.

At 15 minutes, the Los Angeles isochrone captures the standard trade area — a zone where trips are planned but customers are willing to cross neighborhood boundaries. Unlike a 30–80 km² in typical US metros; the range varies 3× depending on road density and barriers circle, the real road-network polygon follows Los Angeles's actual highway corridors, accounts for bridge and interchange chokepoints, and respects the natural and built barriers that force drivers to detour.

Best-fit categories at 15 minutes: Casual dining, specialty retail, auto service, full-service salon, pet supply. The 15-minute isochrone is the standard input for franchise disclosure documents and protected-territory negotiations.

The city-level population of 3,979,576 and a median household income of $65,290 give a sense of Los Angeles's economic density, but the figure that matters for site selection is the population inside the polygon — not the city as a whole. That number shifts dramatically depending on whether you're drawing from a high-density urban core or a lower-density suburban corridor.
