The Geopolis database allows the comparison of urban agglomerations indicators around the world. Brasipolis uses the Geopolis method for Brazil. With indicators such as population, surface area and density of urban agglomerations, we question the concept of ‘‘urban dispersion’’ as used in Portuguese, Spanish and Italian urban studies to describe ‘‘urban sprawl’’. Urban sprawl in Brazil is not as pronounced as in other countries. Dispersion is manifested by a deconcentration of the population in a dense urban system of medium-sized agglomerations.
