In a context of a structural housing crisis exacerbated by rising interest rates, falling household purchasing power, environmental standards and the development of seasonal rental, this project aims to better understand how tension is exerted on the property and rental markets and to produce synthetic indicators for measuring this tension on a fine spatial scale. However, measuring the pressure on the real estate market raises numerous questions to which this project aims to provide some answers. What variables should be taken into account in a synthetic indicator of real estate market pressure? How can we measure housing supply and demand in the private sector? How to measure rental needs and determine the municipalities where they are greatest? How can the 'purchasing power' of resident populations be taken into account when constructing indicators?
