The decision about priorities of housing policies, the dissemination of funding in the different parto of Italy can be helped by regional and local economic analyses. In this light the role of evaluation is examined, in order to show which kind of approach can be referred to each dimension, context and level. After a general introduction explaining the main aspects of the National Housing Plan, an example of integrate assessment of rent market and difficulty in housing access is shown. The result is a scaling that profiles some Italian metropolitan reality, and identify the geographical general/local differentiation among cities/part of cities. All the examples are aiming to demonstrate that only an integrate, multilevel approach, supported by appropriate analysis can succeed in improving policies for increase supply and quality of housing stock.
