What is NOT an observed form of an urban national network?

Question

Quizplus · Accepted Answer

The other three options are all observed forms of an urban national network. Rank-size distribution refers to the pattern where the largest city is twice as big as the second-largest city, which is three times as big as the third-largest city, and so on. Primate distribution refers to the pattern where one city is significantly larger than all the other cities in the country. Non-primate distributions refer to the pattern where no single city dominates, and instead there are several cities of similar size. Relative distribution refers to the pattern where the cities are arranged in relation to each other based on their various characteristics or features, such as their economic activity or population density.
