ABSTRACT To achieve equitable water access, it is necessary to understand and quantify the heterogeneity of water consumption. Thus, this study assessed the spatial dependence of water consumption for Brazil and an urban center. Two spatial autocorrelation tests were applied: the Global Moran’s Index (I) and the Local Indicator of Spatial Association (LISA). It was found that, both at the national and municipal scales, water consumption is not uniformly distributed in space, indicating the formation of clusters of regions with High-High, High-Low, Low-High, and Low-Low aggregation patterns. In this way, water and socioeconomic inequalities in Brazil are highlighted, emphasizing the gap between the Center-South and the North-Northeast regions. Additionally, water and socioeconomic disparities within the city of Fortaleza are also observed, resulting from its urbanization process. Finally, the spatial autocorrelation between water consumption and per capita income is strongly evident at both the national and municipal levels.
