The peoples of southern Mesoamerica, including the Classic period Maya, are often claimed to exhibit a distinct type of spatial organization relative to contemporary urban systems. Here, we use the settlement scaling framework and properties of settlements recorded in systematic, full-coverage surveys to examine ways in which southern Mesoamerican settlement systems were both similar to and different from contemporary systems. We find that the population-area relationship in these settlements differs greatly from that reported for other agrarian settlement systems, but that more typical patterns emerge when one considers a site epicenter as the relevant social interaction area, and the population administered from a given center as the relevant interacting population. Our results imply that southern Mesoamerican populations mixed socially at a slower temporal rhythm than is typical of contemporary systems. Residential locations reflected the need to balance energetic and transport costs of farming with lower-frequency costs of commuting to central places. Nevertheless, increasing returns in activities such as civic construction were still realized through lower-frequency social mixing. These findings suggest that the primary difference between low-density urbanism and contemporary urban systems lies in the spatial and temporal rhythms of social mixing. [ABSTRACT FROM AUTHOR]

We present quantitative data on population size and plaza area in three groups of ancient Mesoamerican settlements: a sample of 30 Late Postclassic cities and towns from throughout Mesoamerica and two regional settlement systems from the Classic period, including south-central Veracruz (the Mixtequilla) and the Palenque region. Plaza size scales with population in a sublinear relationship in all three groups, meaning that larger settlements had considerably less plaza area per capita than smaller settlements. These results suggest that the currently popular interpretation drawn from Classic Maya archaeology that plazas were places designed to hold the entire urban population for passive viewing of spectacles may be incomplete. We argue that the observed quantitative relationships between population and plaza area support the notion that plazas were designed to be used for a variety of purposes—including several types of ceremonies and marketplaces—held at different times following a regular schedule.
