It's true: there are a lot of Subway restaurants in the United States.
Research firm Datafiniti recently looked into which fast-food chains have the most locations nationally, and how the size of each fast-food chain compares to the total number of fast-food establishments in the US. To see what percentage of all fast-food restaurants a particular chain makes up, Datafiniti divided the number of restaurants in each chain by the total number of fast-food restaurants in the US.
As it turns out, Subway restaurants account for 18.5% of all US fast-food restaurants, with McDonald's not too far behind at 11.3%. Together, the two restaurants dominate the fast-food industry — the nearest runner-up is Burger King, which accounts for only 5.7% of all fast-food restaurants in the US.
