This research is basically following the main question: What adds value in a metropolitan
region? What is positive when it comes to measure its efficiency? There are many aspects that
have these adding value possibilities. Among them and as a methodological approach of this paper it has been proposed the diversity measurement and its quantitative analysis. Given the
positive and regulating capabilities of diversity in the urban systems, an analytical model has
been developed in order to assess the distribution of housing prices using variables that allows
calculating diversity in an economical and territorial basis. The parameters involved are
variables such as land use, the distribution of employment, the income level of the population,
transport accessibility, among others. The methodology adopted focuses on assess different
variables and its internal diversity as a measure of both the balance and abundance of preconstructed
indicators. From the above it is possible to draw conclusions of the importance of its
inclusion in metropolitan systems planning.
In the case of the metropolitan region of Barcelona (RMB) and its 164 municipalities the study
show that diversity of located employment, diversity of economic activity including income levels
and diversity of land uses are highly positive factors which have a direct influence in the
metropolitan setting, making a difference on residential market values.
