    Descubriendo la distribución espacial de comercio en ciudades con economías informales
    (Universidad EAFIT, 2020) Saldarriaga Marín, Juan Camilo; Duque Cardona, Juan Carlos
    An economic census aims to record economic activity in a city by collecting geo-referenced survey data. Although its benefits are significant, the costs are very high and, for this reason, it is very rare that the economic census information is up to date and complete. In this work we propose a new methodology to detect and georeference the visible commercial activity in a city or region in an efficient way, generating automated reports of visible commercial activity in a region of interest. This methodology tries to estimate the spatial distribution that allows having an economic census but only for visible commerce. We contrast the results of our methodology with official information from the Chamber of Commerce to estimate the spatial distribution of informal visible commerce or unregistered commerce in the municipality of Envigado.
