This publication contains the results of a survey on improving housing affordability in the UNECE region, conducted in 2020. The UNECE Committee on Urban Development, Housing and Land Management (CUDHLM) organized this survey to explore the views of UNECE member States on key challenges, policies and needs in relation to housing affordability. The aim was to inform the UNECE secretariat how it can better assist member States in developing and implementing solutions, tools, measures and policy instruments for addressing housing affordability challenges. The survey also served to provide inputs into the report "#Housing2030: Effective policies for affordable housing in the UNECE region".
