Urban primacy
From Wikipedia, the free encyclopedia
In urban studies, urban primacy indicates a city whose population is at least twice as large as that of the next largest city in a country. Such a city is called a primate city. In other words, urban primacy can be defined as the central place in a urban or city network that has acquired or obtained a great level of dominance. The level of dominance is measured by the population and the number of functions offered. Higher functions and population will result in higher dominance.
