Abstract
<jats:p>Access to home ownership has become an axis of structural inequality between generations, in a context in which the real estate market increasingly operates as a mechanism for transferring wealth from younger cohorts to older ownership cohorts. To propose the theoretical-methodological design of a new composite indicator, the Intergenerational Housing Equity Index (IEIH), aimed at measuring and comparing internationally the disparity in access to housing between generational cohorts, with the possibility of integration into the monitoring systems of Sustainable Development Goal (SDG) 11. A qualitative documentary analysis of academic sources indexed in Scopus and Web of Science, as well as technical reports of multilateral organizations published between 2019 and 2026, was carried out, adapting the ten-step protocol of the Manual on the Construction of Composite Indicators of the OECD and the Joint Research Centre of the European Commission. Four constituent dimensions of the IEIH were identified (economic access, wealth and wealth transfer, regulatory framework and housing policy instruments, and generational housing adequacy), twelve candidate indicators, and a normalization, weighting, and aggregation procedure with sensitivity analysis. The IEIH complements the existing indicators of affordability and housing adequacy by explicitly incorporating the comparative-generational axis, and lays the methodological foundations for its empirical validation through a panel of experts (Delphi method) and a pilot study in Latin American countries.</jats:p>
