Coverage analysis
What 30 minutes covers in Charlotte.
Charlotte is one of the fastest-growing metros in the Southeast and has a relatively young highway network (I-485 only fully closed in 2015). Drive-time studies need to be refreshed often here because new interchanges and corridors keep reshaping reach in measurable ways.
At 30 minutes, the Charlotte isochrone captures the regional catchment — a zone where trips are planned but customers are willing to cross neighborhood boundaries. Unlike a 100–350 km² circle, the real road-network polygon follows Charlotte'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 30 minutes: Big-box, regional dining, car dealership, furniture, healthcare anchor, sporting goods. The 30-minute isochrone is the standard input for cannibalization studies and multi-unit expansion modeling.
The city-level population of 874,579 and a median household income of $65,359 give a sense of Charlotte'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. Use the tool above to set your actual candidate location, then generate the isochrone to see the real catchment.
