Définition
Price indices for old dwellings (with the Notary-INSEE label) are calculated quarterly by INSEE, and serve to enrich the statistical information available on the French housing market. These reference indices, produced in partnership with the Notary authorities (Higher Council of Notaries and the Paris Chamber of Notaries), are calculated on the basis of net vendor transaction prices (excluding transfer fees, notary fees and agency fees) of sales completed in the quarter.
