Abstract

This paper presents an evaluation, from the user point of view, of the regular population grid, with 1 km2 resolution, that the Spanish National Statistical Institute (INE), has released as a product from the last Population and Dwellings Census 2011. This way of disseminating population data is novel, and has a lot of analytical potential uses, since population is no longer linked to administrative divisions. For the first time this information about the population distribution has been generated using a bottom-up approach, this is, by geo-referencing the population at its place of residence. The availability of another grid at the same spatial resolution, but generated using a top-down approach, this is by spatial disaggregation methods from administrative population data and other auxiliary land cover information, allow us to explore the benefits associated to geo-referencing the population in the context of the methodological changes introduced by the Population and Dwellings Census 2011. In parallel, we are able to evaluate the goodness of the census grid. Additional information Este trabajo presenta una evaluación, desde el punto de vista del usuario, de la malla regular (grid) de población, con resolución de 1 km2, que el Instituto Nacional de Estadística (INE) ha hecho pública a partir de los resultados del Censo de Población y Viviendas 2011. Esta forma de difusión de resultados resulta muy novedosa y ofrece un gran valor analítico. Por primera vez esta información sobre la distribución espacial de la población se ha generado desde abajo (Bottom-up), es decir, a partir del conocimiento de las coordenadas de cada hogar, considerando como tales las del edificio donde reside. La disponibilidad de otra grid con idéntica resolución, elaborada por métodos de desagregación espacial a partir de la población censal por unidades administrativas e información auxiliar sobre coberturas del suelo (Top-down), nos permite examinar las mejoras asociadas a la geo-referenciación de la población acometida en el contexto de los cambios metodológicos del Censo de 2011. De forma simultánea ello nos permite analizar las bondades de la grid censal. Información asociada a este trabajo
