What term describes a series of nearly equal sized cities in close proximity?

The term that describes a series of nearly equal-sized cities in close proximity is "Constellation." This concept is used in urban geography and regional planning to illustrate a pattern of development where multiple urban centers exist that have similar sizes and characteristics, often interacting with each other economically and culturally.

The term captures the idea of these cities functioning collectively rather than hierarchically, where one city is dominant over the others. This arrangement can lead to a dynamic urban environment, fostering competition and collaboration among the cities involved.

In contrast, other terms listed do not convey this specific urban pattern. "Articulated Sheet" refers to a type of structural or material concept rather than an urban pattern. "Woonef" is not a commonly recognized term in urban studies. "Channelization" typically relates to the management of waterways and does not pertain to urban development or the relationship between cities.
