Mapping Transnational Gentrification in the Porto Metropolitan Area (Portugal): Development and Validation of a Multidimensional Index

A multidimensional index successfully quantifies transnational gentrification in the Porto Metropolitan Area, revealing spatial clustering centered on Porto's historic core. The index, built from 16 variables including tertiary education levels, white-collar employment, foreign residents, short-term rentals, and housing rents, shows strong associations with neighbourhood deprivation, property values, tourism, and rising costs. Validated against census data, property tax records, and resident perceptions, it offers a reproducible tool for monitoring gentrification's social, environmental, and health impacts, addressing a gap in metropolitan-scale analysis.
