The OECD Affordable Housing Database (AHD) provides comprehensive insights into affordable housing across member countries, EU states, and key partners. Organized into three dimensions—housing market, conditions, and public policies—the AHD enables easy comparison of indicators like stock, prices, homelessness rates, and policy measures. This robust dataset aids policymakers in evaluating and improving access to affordable housing globally.

The OECD stands out as one of the largest international organizations globally, championing growth and development and representing some of the world's most significant economies. Beyond its economic role, the OECD serves as a leading authority on policy analysis and data. Recognizing housing as a top priority for its members, the OECD has been advocating for a more comprehensive analysis of affordable housing realities.

In response to this need, the OECD Affordable Housing Database (AHD) was established. This database serves the dual purpose of enabling countries to monitor access to high-quality, affordable housing and enhancing the knowledge base for policy evaluation. It aggregates cross-national information from OECD countries, Key Partners, and EU member states.

The AHD organizes indicators across three main dimensions: housing market, housing conditions and affordability, and public policies related to affordable housing. Under the housing market dimension, indicators cover aspects such as housing stock, prices, and tenure distribution. The housing conditions dimension encompasses metrics ranging from overburden rates to the ability to maintain adequate warmth in housing, along with statistics on homelessness. The third dimension, public policies, focuses on variables such as the provision of social housing, subsidies, and regulatory frameworks.

Each indicator within the database offers data, relevant definitions, methodologies, and key findings. This structured approach allows for easy comparison of different countries and their respective affordable housing situations. Furthermore, the indicators address issues of comparability, data reliability, and may include raw data or descriptive information across countries.

In summary, the OECD Affordable Housing Database offers a reliable and comprehensive dataset on affordability within the world's most influential economies, facilitating informed policy decisions and international comparisons.
