The present work aims to define spatial correlations between indicators based on
tourism variables which are quantitative and qualitative in nature. The main objective is
to identify neighbourhoods where there is a conflict of interest between residents,
tourists, hosts, catering sector and other stakeholders involved because of urban
tourism. The methodology proposed is based on static and dynamic variables –
population, short-term rentals, regulated tourist accommodations, catering facilities,
cultural equipment and citizen initiatives– to measure the degree of overtourism.
Research instruments are web scraping, open access data from local and regional
governments, and most read local newspapers to create a database through Geographic
Information System (GIS). Data collection has been analysed on a case-by-case basis
with SPSS statistical treatment programme. These methods have been tested in three
port cities from the Mediterranean arc: Malaga, Valencia and Palma de Mallorca; where
average population is over half a million inhabitants. The key finding is the spatial
correlations between indicators which show common patterns in the urban areas
analysed by GIS mapping. On that basis, touristification thresholds have been
established in order to measure "tourism gentrification" (Gotham, 2005) in-depth. The
diagnosis presented may serve as a road map for local and regional administration to
struggle with touristification through urban policy in the short- and medium-term.
Furthermore, this work is open to new research considering new variables or redefining
the existing ones, as well as new tourist destinations as case studies in order to build a
comprehensive model which allows qualifying the scopes defined.
