House size provides a comparative measure of household wealth that enables archaeologists to track global trends in inequality across a range of sedentary societies. Such approaches hold particular promise for Maya archaeology given its long history of settlement pattern research and recent applications of LiDAR to map large areas surrounding ancient Maya cities. Estimating dwelling size, however, is not a trivial exercise. This article addresses potential confounds associated with geometric-based estimates (volume and area) and compares traditional house size-based measures of wealth with other estimates of house size and quality of life indicators. Settlement pattern data from the Upper Usumacinta Confluence Zone, recently collected by the Proyecto Arqueológico Altar de Sacrificios, combined with previously published excavation data provide a robust dataset to evaluate alternative measures of wealth beyond house size.

The Classic Maya polities of Baking Pot and Lower Dover developed along two dramatically different trajectories. At Baking Pot, the capital and associated apical elite regime grew concomitantly with surrounding populations over a thousand-year period. The smaller polity of Lower Dover, in contrast, formed when a Late Classic political center was established by an emergent apical elite regime amidst several long-established intermediate elite-headed districts. The different trajectories through which these polities formed should have clear implications for residential size variability. We employ the Gini coefficient to measure variability in household volume to compare patterns of residential size differentiation between the two polities. The Gini coefficients, while similar, suggest greater differentiation in residential size at Baking Pot than at Lower Dover, likely related to the centralized control of labor by the ruling elite at Baking Pot. While the Gini coefficient is synonymous with measuring wealth inequalities, we suggest that in the Classic period Belize River Valley, residential size was more reflective of labor control.

During the Late Classic period (a.d. 550–900), ancient Maya settlement spread throughout western Belize, including the Vaca Plateau, a rugged karstic region with high densities of ritually utilized cave systems. Within the past decade, archaeologists have increasingly drawn on LiDAR technology to document the extent of such settlement at local and regional scales. Combined with traditional pedestrian survey, we have begun to amass substantial data on variation within household groups, disparities which may indicate inequality within these communities. Here, we use settlement data generated from the Las Cuevas region to quantify residential variation through Gini coefficients and Lorenz curves. Special attention is given to areal and volumetric deviation of identified households within three samples: (1) the complete 95.25 km2 study area; (2) a 12.25 km2 zone of higher population between the primary centers of Las Cuevas and Monkey Tail; and (3) households situated within 500 m of ritually utilized caves within the study area. Results indicate some degree of variation within household area and volume for all samples, suggestive of unequal access to labor within the region. This research adds to the growing database of Gini-based analyses to improve our understanding of wealth differentials within pre-modern populations throughout the Lowlands.

The archaeological site of Copan was a cultural and commercial crossroads at the southeastern Maya frontier. Research indicates that the demographics and sociopolitical circumstances of the city of Copan and its location within a circumscribed pocket (24 km2) of the larger Copan Valley varied through time. These circumstances not only influenced its social, political, and economic interactions, but likely the size, construction, and organization of households, specifically plazuelas. Copan's plazuelas differ from those located in other Maya regions because they often have smaller house platforms, comprise more than a single patio, and exhibit a larger than normal proportion of informal groups. Gini coefficients, to investigate wealth inequality based on household size using area, volume, and a modified volume, were calculated for Late Classic Copan to allow for comparisons to Gini coefficients from other Maya regions. While the Gini coefficients suggest that wealth inequality at Copan is much higher than in other Maya regions, deeper interpretations of inequality based solely on the Gini coefficients are limited, requiring not only additional geospatial analysis employing a multi-proxy Gini coefficient, but, importantly, a comparison to and a deeper reflection on previous research at Copan.
