Abstract
This article analyzes the determinants and the distribution of Creative Class in peri-urban areas. Starting from Florida´s hypothesis on localization patterns (the famous 3Ts), the article uses unique measures to define tolerance and urban climate, to add innovative determinants and extend the analysis to peri-urban territory in Northern Italy. These measures are tested applying a principal component analysis and spatial regression models. The results partially confirm Florida. Creative class presence is strongly associated with socio-economic determinants, such us public expenditure, presence of creative and no-creative firms, volunteering; less than cultural amenities and technology. Tolerance has more controversial effects.
