Affordability concept became relevant along last decade in housing economics litera-ture and strongly after 2007 with the credit crunch shock. The multiplicity of focuses used in af-fordability analysis as well as the different concepts used to analyze difficulties faced by house-holds entering to housing market, lead to the appearance of a number of definitions and measu-res not always consistent. This paper contains a literature review about housing affordability. The aim is to give a structure of concepts explaining what affordability is understood and show how it is measured. The second part of the paper estimates some affordability ratios for Spain and discusses some relationship with business cycle.
