In shipping usage, a port's hinterland is the area that it serves, both for imports and for exports. The size of a hinterland can depend on geography, but also on the ease, speed, and cost of transportation between the port and the hinterland.
By analogy, it is the area surrounding a service from which customers are attracted, also called the market area.
It was applied also to the surrounding areas of former European colonies in Africa, which, although not part of the colony itself, were influenced by the colony.
A further sense in which the term is commonly applied is in talking about an individual's depth and breadth of knowledge, specifically on cultural or scholastic matters. For instance, one could say 'X has a vast hinterland'.
