Correct. This is the text reference:

The political organization of the Mayas has been described as one of semi-independent "city-states" under no single unifying empire, thus further strengthening the notion of a parallel to Greek civilization. This notion is reinforced by the fact that the most impressive surviving legacies of the Maya are their ruined cities and the artifacts found in them. Ironically, it seems that these cities, for all their religious, civic and ceremonial monuments, were not inhabited by many individual Maya, and remained fairly empty except for ceremonial occasions. The typical Maya focused his or her life in the villages and fields which surrounded the major cities. Here is where corn, the staple of their civilization, was grown, and where they lived out the years of their existence.
