Abstract
Land cover data may be used as indicators of socioeconomic differentiation. Although residential pools are considered as leisure equipment for the highest social classes, it is important to quantify this association. The aim of this paper is to relate the presence of swimming pools to the socioeconomic level of the population of Marília – SP. The geographical location of the swimming pools was obtained by the classification of satellite image, using GEOBIA techniques, and the association with the income of the heads of households was established by the Global Linear Regression and Geographical Weighted Regression. The results confirmed that the swimming pools can be an indicator of the location of high-income families. The model was able to predict the location of the high-income families (income above 10 minimum wages) at 68%. The model showed a better fit in horizontal single-family houses, but poor performance in the central locations of the city, with more vertical dwellings and with few swimming pools per lot.
