Explanation

The 'primate city' concept — that a single city in a country disproportionately overshadows all others in size and national influence — was propounded by the American geographer Mark Jefferson in 1939. Jefferson illustrated it with examples such as London, Paris and Copenhagen. August Lösch is associated with the economics of location, Griffith Taylor with environmental determinism and migration studies, and Walter Christaller with central place theory. None of the other three geographers originated the primate-city idea.
