- ÍtemAcceso AbiertoNightlight, landcover and buildings: understanding intracity socioeconomic differences(2024-02-12) Garcia Suaza, Andrés Felipe; Varela, Daniela; Grupo de investigaciones. Facultad de Economía. Universidad del RosarioMonitoring patterns of segregation and inequality at small-area geographic levels is extremely costly. However, the increased availability of data through non-traditional sources such as satellite imagery facilitates this task. This paper assess the relevance of data from nightlight and day-time satellite imagery as well as building footprints and localization of points of interest for mapping variability in socio-economic outcomes, i.e., household income, labor formality, life quality perception and household informality. The outcomes are computed at a granular level by combining census data, survey data, and small area estimation. The results reveal that non-traditional sources are important to predict spatial differences socio-economic outcomes. Furthermore, the combination of all sources creates complementarities that enable a more accurate spatial distribution of the studied variables.
