Milan City Generates Only 35.7% of Provincial Sales: The Dominance of the Hinterland
Official data, Italian Revenue Agency
In the property landscape of the metropolitan city, the market of the whole province is often identified with the dynamics of the city itself. However, the official data of the Italian Revenue Agency on the Normalised Number of Transactions (NTN) for 2023-2025 show a structurally different reality: Milan city accounts for only 35.66% (about 35.7%) of total provincial sales.
The remaining 64.34% of residential sales takes place in the municipalities that make up the Milan Hinterland. This gap highlights a consolidated polycentrism, in which the urban belt handles almost two thirds of the total volume of residential transactions in the province.
The Three-Year Data: Milan City vs Hinterland (2023-2025)
Between 2023 and 2025, the total volume of homes bought in the Province of Milan rose from 66,876.55 to 70,595.78 NTN, an overall increase of +5.56%. The breakdown between the urban centre and the municipalities of the belt, however, shows widely differing growth rates.

The Reasons for the Geographic Breakdown
The asymmetry in volumes between the city and the province is linked to many structural and demographic factors characterising the Milan area:
1. Territorial Extent and Number of Municipalities
The municipality of Milan covers an area of about 181 km², while the Province extends over more than 1,500 km². The presence of numerous municipalities with heterogeneous infrastructure and residential features ensures an overall supply numerically greater than that of the city alone.
2. Supply Structure and New Construction
While within the municipal boundaries of Milan building activity works mainly on reuse, renovation and the urban regeneration of former industrial areas, in the municipalities of the Hinterland the availability of building land and medium-scale residential development projects has allowed a proportionally higher rate of turnover and new construction.
3. Differences in Prices per Square Metre
The gap in average prices per square metre between Milan city and the first/second ring affects the distribution of volumes. For large segments of demand, the provincial market is the natural outlet for meeting housing needs for medium and large floor areas at lower overall costs.
Comparison of Floor Areas: Centre vs Urban-Metropolitan Belt
Besides volumes, the two components of the province differ clearly in the type of homes traded.
