Abstract
The processes of urban sprawl that have been present over the past two decades in the different strata of the urban hierarchy have also affected, as a whole, medium-sized cities. The urban sprawl has been particularly pronounced during the period of expansive Spanish urbanism, in which many of the municipalities situated in the vicinities of large cities have been affected by major demographic dynamics and (sub)urbanisation development outside the traditional city limits. Sometimes, these processes have been greater than the nearby cities in the urban area where they are inserted. In this study, we examine the general mechanisms identified within an urban crown size (within a radius of 30 km) and at the scale of the municipality, based on an analysis of two distinct periods: one linked to a strong growth dynamic (2000–2008), and another related to subsequent crisis (2009–2016). A group of 23 inner medium-sized Spanish cities has been analysed, taking into account the trends of the population, the surface of unbuilt plots, the built surface, and the amount of housing. We have identified the typologies of their respective urban areas over the two periods considered.

Summary
From the beginning of the new millennium, Spain has been affected by an economic context that has had a major impact on the dynamics and ways of building Spanish cities [1,2]. The processes of urban sprawl are associated with factors of a different nature, but they have acted jointly, in some cases favoring urban dynamics in areas that have traditionally been agricultural being rapidly turned into forms of dispersion from the city This process is part of a theoretical context that has been defined by a lack of agreement in relation to the concept of what a medium-sized city is from the point of view of statistical thresholds. These are framed in a context of urban growth from the end of the last century up to the year 2008, which was an especially intense period for big cities; the dynamics that have affected their metropolitan areas have been much studied by the scientific community. These changes have been observed along the Mediterranean coast and among its islands, where sun and beach tourism have generated a strong demand for second homes [5]
