The main aim of the article is valuing the diffusion of the creative class in Milan. For doing it, I am going to tie up with the Richard Florida’s thesis about the rise of the creative class and his innovative model of regional economic growth, the 3T model: Talent, Technology, Tolerance. First, I describe the characteristics of creatives, their insediative chooses and the diffusion of creative works in Europe and in depth in Italy-. But the heart of the article is the comparison between the creative class in Italy and the creative class in Milan, using the some indicators built by Florida for the study of creatives in the Usa and in Europe. At the end, the conclusions put in evidence points of strength and of weakness in the creative climate of Milan, observations about the model (3T) and some considerations on the last studies of Richard Florida.
