The study compares data on household housing wealth in Italy from Banca d'Italia's Survey on Household Income and Wealth (SHIW) with administrative records from the Real Estate Market Observatory (OMI), with the aim of assessing the similarities between the two sources and leveraging any discrepancies to improve the quality of information. Specifically, it introduces two data integration approaches that provide a more comprehensive representation of the distribution of housing wealth.

The shares of households owning properties are broadly similar according to the two sources. However, some discrepancies emerge: households tend to omit secondary properties during the SHIW interviews, while OMI data sometimes fail to capture all properties due to misalignments in cadastral records, as in the case of inherited properties. Integrating the two sources reveals a higher ownership rate and a less unequal distribution of housing wealth compared with what emerges separately from each source.
