The concept of low-density urbanism has developed in archaeology over the past 20 years to characterize settlements that display the same types of features as nucleated cities (monumental architecture, services provided for a hinterland, division of labor, class differences) but lack dense populations. Ancient cities that emerged in tropical regions typically resemble a distributed urban network (Scarborough and Isendahl 2020) with interconnected and regularly spaced urban centers scattered among dispersed residential and agricultural land. We demonstrate that the Gulf lowlands of Mexico exemplifies this type of urbanism, and we highlight a number of its features related to land use, governance, and sustainability. Given the formidable challenges of understanding a distributed urban network, we advocate approaches that do not impose hierarchical interpretations or discrete territories but, rather, explore the characteristics of the network of places.
