That’s not quite true. While there are more than 13,000 branches in the States, some benighted areas of its vast hinterland are not blessed with ready access to 710-calories salads or a quarter-gallon vat of Coca Cola.

Predictably, the densely populated eastern seaboard has the highest numbers of the fast-food outlets – as represented by the thick galaxy of McDonald’s lights to the right of the map – closely followed by the west coast.

But between the Mississippi and the Rocky Mountains, double cheeseburgers get harder to find.

South-east Oregon, central Nevada and Idaho are all borderline French-fry deserts – “McSparse”, as Steven von Worley, the map’s creator, puts it.

According to von Worley, the “McFarthest Spot” in America – or at least the 48 contiguous states – lies in the grasslands of South Dakota, between two tiny hamlets called Meadow and Glad Valley.

It is a terrifying 107 miles from the nearest McDonald’s as the crow flies – but worse still, a two-hour-minimum, 145-mile journey by car.

British people will be reassured to know that despite the comparatively tiny size of our islands, we still find room for an artery-busting 1,250 McDonald’s outlets.
