Housing inequalities persist as a significant challenge in Western European countries, disproportionately affecting vulnerable groups such as migrants, refugees, low-income households, the elderly, and people with disabilities. These disparities hinder social inclusion, exacerbate poverty, and deepen marginalization. This paper investigates the complex interplay between housing inequalities and social inclusion, exploring the historical and contemporary causes of these disparities, their impact on various social groups, and the effectiveness of policies designed to address these issues. Through comparative case studies of select Western European countries, the study critically examines how different approaches to housing have either mitigated or exacerbated social exclusion. It concludes with recommendations for policy reforms that could promote more inclusive, equitable housing systems across the region.
