The purpose of this paper is to develop the concept and definition of multidimensional urban areas, thereby providing insights into our understanding of the sub-regional structures of household spatial systems. Hence, we propose a framework for strategic planning that considers several areas of household needs. In order to achieve this goal, we develop a multicriteria methodology to define the territorialisation of the region of Catalonia (Spain). We first analyse the different methodologies used to define territorial areas based on economic criteria, for example, those used to construct travel-to-work areas (TTWA), among other methods. Thus, in practice several criteria and techniques are used to organize a territory, including administrative areas, commuting-based algorithms, and gravitational techniques. Finally, these points help us build a system of multicriteria urban areas that is consistent with the overall use of time by individuals.
