This report provides an overview of the progress achieved in the provision of affordable housing in the region of the United Nations Economic Commission for Europe (UNECE). Given the immense diversity of responses across the 56 countries in the region, the emphasis is on practices that are conducive to the provision of affordable land and housing. The report has three specific objectives. Firstly, it explores major regional trends in housing conditions with an emphasis on availability, quality, and tenure choice. Secondly, it analyses housing policy responses to address major challenges such as growing affordability problems, access to social housing, and improvement of substandard housing conditions. Thirdly, the report provides recommendations for local, national, and international policy initiatives that could contribute to the provision of affordable housing in the region.
